The operation of the machine is not done once and for all, and it is necessary to pay special attention to the state of the machine during each packaging process. In order to effectively manage and maintain the packaging machine and control the product quality, in addition to regular maintenance, the auxiliary personnel and feeding personnel of the equipment also need to follow the following operating procedures.

Auxiliary personnel

• Turn on the power switch.
• Check whether the air pressure is sufficient (must reach 0.6Mpa).
• Click the host to start, and check whether each action is working properly.
• Check and clean up each box room.
• Put the bag, load the material, put the material box.
• Click the host to start.
• The product that is packaged in vacuum for the first time should be checked whether the seal is firm, whether the suction is tight and through the water check(Must check vacuum chamber 1-10).
• During the production process, check the product sealing and pumping conditions continuously.
• Every 2 hours after the machine runs, must be the top cover of the machine, bag clip, and funnel mouth, carried out with an air gun clean.
• The bag or material dropped on the machine, should be hooked out with a hook, do not take it by hand.
• The relevant “parameter settings” on the display screen shall not be changed without permission.
• When the machine is running abnormally, report it to the monitor or maintenance personnel in time, and do not continue to operate.
• Turn off the power after the work is over, disassemble the material tray and measuring cup for cleaning and disinfection.

Feeding personnel

The main responsibilities of the feeding personnel are as follows:

• Sterilize the elevator, material tray and measuring cup with alcohol.
• Put in materials according to regulations;
• Staff needs to complete the packaging of the existing materials on the machine, pull the remaining materials back to the cold storage, and clean up the remaining debris on the machine, then they can rest.
• When the delivery of materials is abnormal, press the emergency switch in time, do not continue, and report to the monitor or maintenance personnel in time.
• During the feeding process, if any material falls, needs to be stopped and taken, do not take it while the machine is running.
• Do not feed or take material above the poke cylinder.
• Clean and disinfect the machine after work.

All operators must abide by the above operating procedures to ensure safety.

Correct operation mode will maximize the value of the equipment, but also can extend the service life of the equipment to the greatest extent, to ensure the quality of the equipment, so the equipment should be used in accordance with the operation process.

This guide applies to our premade pouch packaging machines and automatic vacuum packaging machines.

In order to better let customers understand the subsequent maintenance and repair of the equipment, we also briefly listed the related matters that maintenance personnel should pay attention to in the article Packaging Machine Maintenance Guide.

In addition, we have also written the Machine Preventive Maintenance Schedule, which can be used as a reference for work content.

In 2019, the market for Premade Pouch has exceeded 9 billion USD, It is still growing at a rate of 4% every year. Maybe you have found that the goods on the supermarket shelves are beginning to have more and more exquisite and practical packaging bags. In fact, most of them are premade pouch. Premade pouch occupies a large part of the packaging bag market.

There are many reasons why premade pouch can occupy the market. The main reason is that more and more people have met their basic needs for food and clothing. After casual snacks began to rise, consumers began to pursue products with exquisite appearance and good consumer usability. In addition, due to the maturity of packaging automation, the overall cost of the premade pouch packaging line has been reduced. The rise of the concept of green and environmental protection makes the company more inclined to use premade pouch that saves materials and waste to cater to the public’s preferences.

For our research on green packaging, you can read The Future of the Packaging Industry —— Green Package

Productive Material

Although the types of packaging are dizzying, the materials of the packaging bags are similar. Most companies on the market use plastic as materials for cost and performance considerations. Sometimes companies use paper as materials to highlight their products’ organic and natural characteristics. A small number of companies use metal materials (not Complete metal, metal is only used as a plating), which makes it look different, but it also greatly increases the cost.

Market

The largest application market of the premade pouch is the food industry, followed by medicine, agriculture, cosmetics, etc. According to geographical division, Europe and Asia are the two largest markets. The European market accounts for about 25% of the global market of premade pouch due to the long development time of the industry and high penetration rate. In Asia, due to its large population, and many regions also have complete industrial chains, its market accounts for about 30% of the global market. The industry generally believes that Southeast Asia has great potential in the future growth of the global premade pouch market. According to the closure type of packaging, about 45% of the overall market uses tear notch, about 35% uses spout, and about 15% uses zipper. The remaining 5% is other types.

The current packaging machine market has not yet seen a large-scale monopoly manufacturer, but many small and medium-sized manufacturers are forming a series of end-user-based alliances through acquisitions and partnerships. This’s because more and more complex packaging methods involve more and more components so that this industry more and more complex. Many companies use cooperative mergers and acquisitions to stabilize supply and control prices, resulting in the trend of oligopoly.

Type

As the market of premade bags expands, its demand is also in an increasing trend. Premade bags are the most widely used bag type in packaging machinery. Most of the bags that can be found in daily life are premade pouches. Subdivide the premade bag, there can be many different names.

Stand-Up Pouch

One of the biggest advantages and main features of the stand-up pouch is that the pouch can stand. Any bag that can stand can be classified into a stand-up pouch. The bags standing on the merchandise shelves can be more easily selected and noticed by consumers, the external conditions of the stand-up pouch and its uniqueness in product printing and promotion, merchants and enterprises can carry out product promotion printing or corporate culture promotion on the front, back and bottom of the stand-up pouch according to actual needs. Stand-up pouches are widely used in the packaging of granules, powdered food, and beverages. This packaging form makes it stand out among many ordinary packaging bags. On a global scale, people’s demand for stand-up pouch is also increasing day by day.

Stand-up pouch is a general designation, it in the form of many, the most common is with zipper spout and tear notch. They are all reusable. In North America and Europe, the green environmental protection concept more thorough popular feeling, so there is a higher demand for reusable prefabricated bags. People’s market demand for ordinary sealed bags is also increasing year by year.

Manufacturers are increasingly choosing biodegradable and recyclable materials to make bags. With the gradual development of urbanization and industrialization, people realize that environmental protection is imminent. With the improvement of living standards and the growth of per capita disposable income, reusable packaging is more and more popular among people. In various industries, the advantages of premade bags have been discovered by people, which is also an important reason for the gradual expansion of the premade pouch market. In the Asia-Pacific region, especially China and India, the demand for premade bags is gradually increasing.

Pillow Pouch

Pillow pouches and stand-up pouches have always been the two giants in the global flexible packaging market, occupying a major position in the flexible packaging market, and pillow pouches account for slightly higher proportions in this market than stand up pouches. The market for pillow pouches has always been large, and many products around us are also packaged in pillow-shaped packaging.

Pillow pouches can pack a lot of objects, liquids, powders, and solids can all be packed in pillow pouches. It can be applied in a wide range of fields, such as the food industry, and pharmaceutical industry. Common products around us can be packed in pillow-shaped pouches.

Europe and North America produce more PET materials, so there are mature pillow bag packaging markets in Europe and North America. In recent years, the growth rate of the pillow bag market in the Asia Pacific region is higher than that in other regions. In China and India, the pillow bag market has been showing steady and rapid growth. This is mainly due to the increasing tendency of consumers in these two regions to use convenient and attractive packaging, rich and colorful printing, and easy-to-use packaging makes pillow bag packaging more and more popular in these two countries. Of course, the low price is also a factor that cannot be ignored.

Pillow pouches are sealed at the bottom, top, and back, which reduces the use of packaging materials compared with other packaging forms.

Stick pouch is a special form of pillow pouch. This is a longer and narrower pillow pouch, shaped like a stick, which is often used to pack small items such as instant coffee and brewed milk tea.

Spout Pouch

Spout pouch, as the name shows, is a bag with a spout. Also called fitment pouch, because the spout part usually needs to be made separately and used in conjunction with the bag body. 

Spout pouches are widely used in liquid packaging. Compared with glass bottles and plastic bottles, bags with spouts save more space in transportation and storage, can transport a larger number of bags. Because of the softness of the bag, it also reduces the possibility of breakage of the outer packaging during transportation. For example, glass bottles must be shatter-proof during transportation, which increases the cost of packaging and transportation. As for the spout pouch, it can be said that there is no such problem in this regard.

Spout bags are more popular when packaging liquids with weaker fluidity. When packaging liquid materials such as ketchup and mayonnaise in a bottle, when the remaining amount in the bottle is reduced, the remaining sauce is always not well and completely taken out. In the long run, this will inevitably cause food waste. At a time when Green Action is becoming more and more popular, such a phenomenon is obviously not what we want to see. The body of the spout bag is made of recyclable materials, and the body is soft and easy to squeeze so that 99.5% of the material in the bag can be taken out. In addition, compared with ordinary plastic bottles, bag packaging uses less plastic, which means that bag packaging can be more environmentally friendly.

Nowadays, more and more liquid beverages are packaged in spout bags. Because compare with bottle, the spout pouch is occupied less space, and it is more suitable for people to carry around.

In the global market for spout bags, North America and the Asia-Pacific region account for the two most important parts. They are the two largest markets for spout bags, followed by Europe.

Paper Pouch

Looking around life, more and more paper packaging appears around us. Fast-food restaurants such as McDonald’s and Burger King have long used paper to package food. Some roasted nuts and roasted foods also use paper packaging. Bakeries also choose to use paper packaging to store freshly baked bread. The application range of paper packaging is gradually expanding, and the advantages are gradually being known. More people choose to use paper packaging instead of plastic packaging bags. Environmental protection and degradability is an important breakthrough in the form of packaging.

Paper pouch is directly made from wood, so it is also more expensive. The increase in cost and the increase in profit cannot form a good balance and coordination. It is for this reason that paper packaging is not as widely used as plastic packaging.

Kraft pouches are an important category in paper packaging. There are many types of Kraft paper, including natural Kraft paper, colored Kraft paper, printed Kraft paper, and so on.

Kraft paper pouches are different from the paper packaging of food in fast-food restaurants. Kraft paper has better strength and durability and is more suitable for packaging some items with a certain weight. The increase in strength and durability has increased the number of repeated uses of kraft paper, which is more in line with the requirements of environmental protection. Like ordinary paper packaging, kraft paper is made of biodegradable material, which provides packaging manufacturers with unparalleled opportunities in the food, beverage, and pharmaceutical industries. The increase in tear resistance allows manufacturers to increase their interests, and make consumers feel better.

The Asia-Pacific region is the largest user of Kraft paper pouch and has always occupied a dominant position in the Kraft paper pouch market. Japan, China, and India are the three main markets. In recent years, the demand for Kraft paper in Europe and the United States has also increased significantly. Driven by regulations and urbanization, people’s awareness of environmental protection has increased. The U.S. government has implemented more stringent regulations on environmental protection. In Europe, the government has initiated many environmental protection programs, which have increased the use of Kraft paper year by year.

Flat Bottom Pouch

The biggest distinction between the flat bottom pouch and other stand-up pouch is the bottom of the flat pouch is a flat surface. This design allows the bag to stand more stable.

For food manufacturers, the bottom design of the flat bottom pouch allows more items to be placed in the pouch, and this design is more cost-effective. For pouch manufacturers, compared with ordinary standing pouches, the flat-bottom design saves more raw materials for manufacturing.

The width of the flat bottom pouch is narrower than most ordinary standing pouches on the market. Therefore, when flat bottom pouches and other stand-up pouches are placed on the shelf together with the same capacity, the flat bottom pouches will always be higher. On the same shelf, the number of flat bottom pouches that can be placed is relatively large.

The design of flat bottom pouch has an advantage that other pouches don’t have: the flat bottom pouch has 5 planes that can be printed, which can make the type of flat bottom pouch more plentiful. Another reason that flat-bottom pouches are so attractive to manufacturers is that the open mouth of the flat-bottom pouches makes it easier to fill products. The larger receiving opening allows materials to enter the bag more quickly and conveniently, which is an advantage that other types of bags are difficult to achieve.

On the whole, when customers are faced with choosing a product in front of the shelf, the flat bottom pouch has more chosen by customers because of higher and richer forms. The flat-bottom pouch is square and more beautiful, so it is always selected by the high-end food industry. However, the cost of manufacturing flat-bottomed bags is relatively high.

Flat bottom pouches are mostly made of plastic or paper and are used in food and pharmaceutical industries. North America is the largest market for flat bottom pouches and will continue to maintain a relatively large growth rate for a period of time in the future. The utilization rate of flat bottom pouches in the Asia-Pacific region is also relatively high. In the future, the Asia-Pacific region will continue to grow at a rate higher than the average growth rate.

Gusseted Pouch

The appearance of gusseted bags is somewhat similar to that of flat bottom pouches, and they have certain similarities. The difference is that the connection of the gusset pouch will be stronger. Therefore, the gusseted pouch can bear more weight. The bottom of the gusseted pouch is also flat, like a flat bottom pouch, the gusseted pouch can also contain enough materials and can be placed on the shelf steadily.

Gusseted pouches are mainly made of plastic or paper with plastic film. Both ordinary packaging and vacuum packaging are suitable for gusseted pouches. Gusseted pouches are also suitable for the installation of some dry materials, such as coffee beans, tea, rice, and other baked products.

Gusseted pouch, as a pouch type, can also be divided into two types: side gusseted pouch and bottom gusseted pouch.

We simply understanding that the side gusseted pouch is to reinforce the side corners of the package, and the bottom gusset pouch is to reinforce the bottom of the pouch. One of the biggest differences is that when we disassemble the pouch, we will find that the side of the side gusseted pouch will present a shape similar to a triangle, while the side of the bottom gusseted pouch will have a shape similar to a quadrilateral. In other words, when the manufacturer wants to enrich the packaging style, the side gusseted pouch can have 5 sides for the manufacturer to create, while the bottom gusseted pouch has only 4 sides. Due to these characteristics of the bottom gusseted pouch, it will be larger than the side gusseted pouch.

Gusseted pouches are also called quad seal pouch or box pouch in some cases.

Sachet Bag

Sachet bag is a general term for a kind of simple small bag, at present, disposable tea bags, instant coffee, shampoo, cosmetic samples, etc. are all packaged in sachet bag. This form takes advantage of people’s consumer psychology, especially in countries and regions with lower income levels. Low income makes it impossible for people to afford higher-priced items, and sachet pouch is rapidly gaining a certain advantage in the packaging market of these countries and regions due to its advantages of small quantity and low price.

In Egypt, 20% of the people live below the poverty line, and people are more inclined to choose a small-sized product. Local retailers are seizing this consumption characteristic and seizing the opportunity to open the sachet pouch market in the local area.

Plastic is the most common manufacturing material in sachet pouch. The weight, low price, compression resistance, and tensile strength of plastic are all good choices for the manufacture of sachet pouch. Plastics can also be printed to enrich the shape of the packaging so that more consumers can choose it.

Zipper Pouch

A reusable zipper is provided at the sealing of the packaging bag. Consumers can seal multiple times during use. At the same time, the zipper can also lock the materials in the packaging. Because of the moisture-proof and waterproof functions of zipper pouches, they are becoming more and more popular all over the world. At present, the largest contribution to the global zipper pouch market is the North American market. It is expected that in the next few years, Europe and the Asia-Pacific region will also make a significant contribution to the zipper pouch market. In China and India, where the food packaging market is becoming stronger, the demand for zipper pouch is increasing due to the influence of environmental protection concepts. In Europe, people who have a higher standard for food safety and hygiene are affected by relevant environmental protection policies and regulations. Driven by the green and healthy market, the demand for zipper bags will also have a higher level in the next ten years.

There is also a special form of the zipper pouch, which is the Inno-Lok bag. The difference is that the zipper installation position of the Inno-Lok bag is located inside the bag. When the user opens the zipper, he generally needs to tear off the wrapping paper on the outside of the zipper according to the prompt on the outside of the packaging bag. Inno-Lok bags are generally larger in volume and size.

Three/Four Side Seal Pouch

The three side seal pouch is simple to manufacture and has various forms. The size and capacity can be customized according to the different requirements of customers. At the same time, three side seal pouches are used for printing and marketing that conforms to the public’s aesthetics. As a result, more and more people use three side seal pouches. North America and Western Europe have always been the main market for three side seal pouches. The utilization rate of three side seal in the Asia-Pacific market, dominated by China and India, is also increasing.

Four side seal pouches are used more in the food and personal care fields. In the beverage manufacturing industry, the market valuation of four side seal pouches is expected to reach 5.3 billion U.S. dollars in 2024. The growth rate of the four side seal pouch market in the personal care industry is expected to exceed 7% in 2024. Consumers and product manufacturers continue to increase their demand for four side seal pouches, which has driven the growth of four side seal pouches.

The growth of the tourism industry has increased the demand for food in small bags. Four side seal pouches have replaced the rigid packaging of traditional cans and have become a new form of travel for many people.

Degassing Valve Pouch

The degassing valve pouch is a pouch that has a small application range but can play an important role in a specific field.

The degassing valve pouch was originally designed for coffee packaging. The roasted coffee beans will generate a lot of gas in the confined space. The design of the de-air valve is to keep the pressure inside the bag approximately the same and at the same time isolate the air from outside the bag to ensure the freshness of the coffee beans in the bag.

When the material in the pouch produce gas, the air pressure inside the bag will be slightly higher than that outside the bag. At this time, the de-air valve will be opened to discharge the gas in the bag. Don’t worry about the gas outside the bag entering the bag when the degas valve is opened. The de-air valve is a one-way exhaust port, and the gas can only go out but not in.

Now the degassing valve bag is mainly used in coffee, pet food, and other items that are prone to fermentation to produce gas.

Twin Bag

At present, there are not many twin bags made of plastic film. Twin bags are more often made of canvas in our daily lives. With the improvement of living standards, people began to have higher requirements for hygiene. As a result, twin bags made of plastic film have gradually increased. Now, some of the facial masks launched on the market begin to separate the facial mask essence and the facial mask paper to seal the two objects used at the same time in two different spaces; in the food industry, the food and the sauce are also beginning to separate of packed twin bags. Merchants claim that this kind of packaging will be more hygienic. The two bags are connected together, if it is not deliberately removed, the two bags will not be easily separated. This design is also for the convenience of consumers to carry.

Flat pouch

Flat pouches have very little space and can hold a limited number of items. Flat pouches are commonly used as preservatives in food packaging.

Of course, it is not to say that the size of the flat pouch is as small as the preservative packaging. Flat pouches can also pack small items. For example, product samples, etc. In terms of marketing, the flat pouch has two sides that can be printed, which is equivalent to the entire visible side of the flat pouch that can be used for promotion.

Doypack Pouch

Doypack Pouch refers to a standard standing bag, also known as Doyen Pouch. When the bottom is sealed in a “K” shape, it is also called K-seal pouch. In fact, Doypack Pouch is a trademark registered by an early French company, and its name is taken from DOYen PACKaging.

Double Doy pouch is a newer bag. The bag can stand on the top and bottom, similar to a cylinder, and is used more in the North American market. Double Doy pouch is very different from other packaging, it is easy to stand out and be chosen by consumers when placed on the shelf.

Perforation Pouch

Perforated pouch is a general term, the main sign is that there will be a hole left by the perforation in the seal of the bag. This hole will not affect the material in the bag, nor will it affect the use of the bag. In the process of shopping malls, this kind of hole is generally used for hanging, saving the space of the bag on the shelf.

Top Seal Pouch

As the name describes, the top seal pouch is a type of packaging bag that is sealed at the top of the packaging bag. Most of the stand-up pouches on the market are top seal pouches. The material in the bag is accumulated at the bottom of the bag, so the top seal pouch can make the bag stand more stable.

Therefore, the application of top seal pouches is still very wide, and consumers and manufacturers are more willing to choose top seal pouches.

Tear Notch Pouch

A tear mark refers to a gap in the seal of the package, which can be easily opened by the user. The range of tear notch pouches is very wide, as long as there is this gap in the package, it can be called a tear notch pouch.

Window Pouch

Ordinary premade pouches are completely sealed and opaque, and consumers cannot see the shape of the internal materials through the bag. In order to meet this demand of consumers, premade pouches with windows have been produced. Open a small opening on the ordinary prefabricated bag and supplement it with a transparent plastic film so that you can see the inside of the bag.

Bag Label Pouch

In order to make customers notice, and to increase product sales, promote the product, or for other purposes, manufacturers usually put a striking label on the bag of the product. Such a bag is a bag label pouch.

New types of bags are always produced in continuous updating. The selection of pouches needs to consider many factors, combine the characteristics of different materials and the sales effect that the seller wants to achieve, and then choose a suitable pouch type in order to achieve the fastest conversion of benefits.

Every customer who purchases machinery, in order to minimize damage to the equipment you purchase, and to bring you the most comfortable user experience, the operators you equip the machinery with should understand the repair and maintenance of the equipment, according to their maintenance, repair capabilities and the familiarity with the equipment, we can divide it into junior technicians and intermediate technicians.

Junior Technician

Junior technicians are mainly responsible for the daily maintenance and simple repair of equipment.

Equipment Maintenance

After the equipment is unpacked, before the first use, and during the daily use of the machine, junior technicians need to inspect the machine. The main inspection components are the whole machine clamp, bag feeder, vacuum chamber, filling system, and trays, etc. Junior technicians need to ensure that these parts are free from foreign matter, noise, loosening, and other unusual phenomena before use, at the same time, check that the protective cover is intact and that the safety device is sensitive and effective. This is the prerequisite for the stable and smooth operation of the machine, and it is also a very important procedure to ensure the safety of personnel when the machine is used.

Vacuum turntable and bag feeding turntable are two main parts of packaging machinery, which directly affect the final packaging effect. Therefore, these two parts should be subjected to daily maintenance work such as inspection of movable bushings and Joint bearing, lubrication, and tightening of screws. In addition, the gears and guide rails of the vacuum turntable should also be taken care of and regularly lubricated. If there is a problem with these two parts, the effect of the packaging will inevitably be affected, and it will further affect the income, which we do not want to see.

In addition, junior technicians also need to check the oil level of the pneumatic triplet and the blockage of the filter. Also, check each compressed air pipe to ensure that there is no air leakage, that the cooling water pipe does not leak water and the pressure is normal, and that the water level of the cooling water tank is normal and there is no leakage.

A huge machine is composed of many small parts. Even a small screw plays a decisive role in the normality of the machine. Loose screws are the easiest to solve but also the most common problem. Usually, we need to pay special attention to the condition of the screws to ensure there are no mistakes at the critical moment of mechanical operation.

The above are the daily inspection items that junior technicians need to do before using the machine for the first time and before using the machine daily.

Simple Maintenance

In addition to daily inspections, junior technicians also need to perform simple maintenance on the equipment according to the inspection, such as timely replacement of suction cups, heat sealing sheets, and silicone strips, etc. And adjustment of the tightness of the conveyor belt. The vacuum chamber is very important for the tightness of the vacuum product. If the sealing strip is damaged or aging will affect the normal operation of the machine, the vacuum packaging effect will also be problematic.

The mechanical equipment needs to adjust the various parameters of the mechanical operation through the size of the packaging bag in time, this also requires the participation of junior technicians. According to the requirements of the product packaging bags, adjust the machine clamping, bag feeding, turntable speed, filling speed and capacity and heat sealing, etc.

According to the responsibilities of junior technicians, it is also necessary to check the safety measures and performance of the protective cover of the equipment, and install the missing external screws of the equipment. Junior technicians need to adjust and modify various parameters according to product requirements.

Intermediate Technician

In addition to the equipment maintenance and repair duties, corresponding to the junior technicians, the intermediate technicians also need to be responsible for the annual or quarterly maintenance of the equipment, and they also need to be responsible for some more complex repairs.

Equipment Maintenance

Regarding the equipment maintenance of intermediate technicians, it is mainly about two aspects. One is the first-level maintenance during each vacation; the second is the second-level maintenance once a year.

First-Level Maintenance

Throughout the year, the equipment is always used day after day, so the rare three to five days vacation is an important time for major maintenance of the equipment, just like people under long-term stress need vacations to relax and adjust the state. Maintenance of the machine during the holidays is very important and must be done.

During the holidays, the main things that intermediate technicians do are:

• It is necessary to check the oil level of the main drive motor and reducer. If it is insufficient, replenish it in time.
• Check the main transmission bearing and cam of the machine body, adjust the screws in time, and tighten them. At the same time, add oil to lubricate the parts.
• Check and replenish the oil level of the vacuum pump, check and tighten the vacuum pipe joints.
• Check and adjust the sealing performance of the air distributor, if there is a problem, add vacuum silicone grease in time.
• Check the various parts of the equipment, such as trays, machine clamps, vacuum chamber, conveyors, chillers, etc.

The above inspections and adjustments are all in order to allow the machine to operate normally in the next working cycle and reduce the occurrence of faults and problems. For some models, we are also equipped with automatic maintenance functions, such as automatic lubrication system

Second-Level Maintenance

Second-Level maintenance is recommended at least once a year. The main content of the Second-Level maintenance is to replace the oil of the main engine, reducer, and tray. Replace the vacuum pump oil and the filter includes air filter element and exhaust filter element.

Equipment Repair

In addition to First-Level Maintenance and Second-Level Maintenance, intermediate technicians also need to repair the equipment. The main contents are:

• Deal with and replace the air leakage of the air distributor and vacuum exhaust pipe.
• Adjust and repair the material box, filling system, and air cylinder.
• When the failure of the heat-sealed parts is not caused by the failure of electrical and mechanical parts, intermediate technicians need to troubleshoot and deal with problems such as insufficient air suction and poor sealing of the heat-sealing.
• Replace the damaged cooling water pipe joints, air joints, and air pipes.
• Handle simple the machine running, emitting, dripping, and leaking faults. When high temperature and high pressure are involved, professional maintenance personnel are required to participate.

Other

Besides, some special climate also require special maintenance, for which we wrote —— Guidelines for safe winterize of packaging machines. In addition to correct operation, the normal use of equipment also requires attention to daily maintenance. This is the best way to save costs.

This guide applies to our premade pouch packaging machines and automatic vacuum packaging machines.

Liquid filling machine is an automatic filling machine that can fill liquid such as water, wine, juice, ketchup, cream, honey, and other materials with certain fluidity into bottles or bags. This machine replaces the traditional manual filling method and reduces the input and use of labor. But at the same time, the maximum optimization of production time and benefits has been achieved. The formed liquid products we see in daily life all need to be filled through liquid packaging equipment.

For the classification of liquid filling equipment, we have many different standards. 

The way materials are transferred from the storage bin to the packaging container often differs according to the characteristics of the materials. According to different principle of transmission driving force, we can simply divide the common liquid filling methods into the following:

Gravity filling

Gravity filling is to fill the material in the storage bin into the packaging container through the material’s own gravity.

Most common liquids have high fluidity, and widely used bottle packaging is one of the most common liquid packaging methods in daily life. The method of gravity filling does not have very strict requirements for the container, plastic bottles, glass bottles and other bottles can be used. Gravity filling is a good choice when the producer has a strong material flow. The filling material pipe extends into the bottom of the bottle to prevent liquid splashing and reduce waste. The filling quantitative error in the packaging container is small. Most of the bottled liquid beverages that we can see in our lives are filled by gravity.

The particularity and convenience of gravity filling make gravity filling the most common method of liquid filling. High precision, fast speed, meet the production requirements of larger output, can produce greater economic benefits.

Piston filling

A simple understanding of piston filling, its principle is to use the method of increasing pressure to press the material into the package.

It is best to fill the material with the piston filling method with the liquid with slight viscosity and poor fluidity, such as ketchup, cake liquid, gel, etc. There are many types of piston filling machines, including automatic linear piston filling machines that can fill quickly and accurately, top piston filling machines, entry-level desktop piston filling machines, and other models. A variety of piston filling machines can meet the packaging of most light viscous liquids on the market.

The application of the piston filling machine solves the packaging of light viscous liquids. It is widely used in ketchup, thick sauces, and other sauces without granules. It is not limited by the shape of the filling container and is flexible in operation. It is especially suitable for liquid packaging which requires certain precision. The piston filling machine occupies a small area and is easy to operate. It is an entry-level model for liquid filling.

Pump filling

For highly viscous liquid materials such as honey, shampoo, face cream, etc., the material cannot be filled into the container by falling by its own gravity. Because of the high viscosity of the material itself, the filling speed of gravity filling and piston filling cannot achieve the desired effect. Therefore, it is necessary to rely more on the power provided by external machinery for filling.

Pump filling is one such filling method. Through the pump system used in the machinery, and then cooperate with the valve and other mechanical parts to achieve the purpose of conveying high-viscosity materials, and realize the packaging of such high-viscosity liquid materials.

For the filling form of liquid filling equipment, liquid filling machine can also be divided into linear filling and rotary filling, etc. Different classification criteria will produce different classification results. However, it still falls under the category of gravity filling, piston filling, and pump filling.

Light, the most common substance, is hard to capture, but it affects our daily lives all the time.

People have used light as a resource for a long time. The use of light plays an irreplaceable role in the development of human society.

Origin and History

People’s research on polarized light began in 1669. Danish scientist Rasmus Bartholin discovered that birefringence occurs when light passes through the  Iceland spar, that is, two beams of light are refracted. Of these two lights, one follows the known optical theory at that time, while the other is an “unusual light” outside the scope of people’s theoretical knowledge. Rasmus Bartholin was unable to explain this phenomenon with the known optical theory at the time. Therefore, since then, people’s theoretical research on light has taken on a new direction.

The concept of “polarization” originated from the “father of polarization”: Étienne-Louis Malus. His painstaking research, deduced from the experimental results known  Malus’s law: I = I (Ο) cos²θ. (where “I” is the initial intensity and ”θ” is the angle between the light’s initial polarization direction and the axis of the polarizer). This research result is of great significance for future optical research.

Since then, a steady stream of people have joined the research team of optical principles, and the theory of optics has been constantly developing and improving.

Application and Development

In the current social development, the principle of light polarization is widely used in various occasions. Polarization theory of light is used in geology, seismology, chemistry, astronomy, and other fields.

In the food packaging industry, polarized light is also quietly playing a role.

The heat-sealing of the package is a process in which the plastic packaging material used for packaging is appropriately melted by increasing the temperature, and then a certain pressure is applied to re-bond the plastic packaging material.

During the heat-sealing process, as the temperature rises, the original polymer chains are broken and the hydrogen bonds change, which causes the material to pile up even more tightly. For some plastic films, the birefringence principle of polarized light can be used to enhance the observation of thermal seal conditions. The reason for this operation is to judge the heat seal of the plastic film by comparing the difference in the transmittance of visible light through the plastic film.

After the temperature rises, under the action of pressure, a series of changes of the sealing material are the prerequisites for determining the change of visible light transmittance. According to the light transmittance, the crystallinity of the seal can be further inferred, and the uniformity of crystallization in the seal area can also be checked.

From the common understanding, the uniform crystallization, that is, good sealing effect. Under the irradiation of visible light, the overall sealing area will show a similar color tone. When the crystallization is not uniform, that is, the sealing effect is not good, the different sealing effect will show a different color of light.

The color of the light will be different because of the difference in sealing material and thickness. However, in the same sealed packaging, people can according to the light through the plastic film sealing presented by the different colors, to judge whether there is uneven  heat-sealing crystallization on the packaging sealing.

In industrial applications, the use of polarized light can quickly help people identify defects in the heat seal. But the process has rarely been used in practice. There are many reasons for this, among which cost and efficiency are the two biggest factors. In the operation process of the packaging machinery used today, after the heat-sealing seal is recognized by polarized light, heat-sealing packages with poor sealing performance cannot be effectively selected and reheat sealed. Secondly, people’s requirements for heat-sealing have not reached a very strict evaluation standard, and a small part of the defects left in the heat-sealing will not have a great impact on the packaging and the materials in it. Under the dual pressure of cost and efficiency, the detection of heat seal is gradually reduced in practical use.  

There are many ways to check the heat seal, and the use of polarized light is only one of them.

Canning is one of the most common ways of packaging food around us. We can find canned meat, canned fish and canned fruit in the supermarket. The packaging method of cans preserves the shape of the food inside the cans, and the hard shell provides convenient for transportation and stacking of cans. However, looking back at the development of canning, like other great achievement, this is not happened overnight. Nicolas Appert, known as the father of canning, has extensive experience in the food industry. A former worker at a pickled cabbage factory, winery, candy factory and restaurant, when he ran his own candied food business, he found that selling fruit pulp and wine, and he found that in the same storage environment he believed, some foods were prone to spoilage, some can be kept for a long time. In order to solve this puzzle, he began to explore the reason.

At the beginning of the 19th century, the issue of food supplies to the army made the French government anxious at the time. Rushing on the road and the hot environment accelerate the speed of food spoilage. Food cannot be provided in time, which will inevitably lead to a decline in the physical fitness of the soldiers participating in the war and weaken the combat effectiveness of the troops. In order to solve this thorny problem, the government at that time took out a large bounty to find a way to preserve food for a long time.

Nicolas Appert discovered a bottle of juice that had not been used for a long time but had not gone bad, so he began researching ways to extend the shelf life of food. Nicolas Appert conjectured that the spoilage of food may be caused by air. In Nicolas Appert’s view, the glass bottle was the device that could be used at that time, with the least air penetration. Therefore, because of this its material and the advantages of holding more things, the wide-mouth glass bottle has become the object of Nicolas Appert’s choice of installation food.

Finally, in 1804, after nearly a decade of hard and repeated experiments, Nicolas Appert discovered the mystery. He found that by sealing the food in the bottle and heating it appropriately, the food in the bottle can be stored for a longer period of time without spoiling. 

After many attempts, Nicolas Appert stoop up again in the failure of the experiment. At last he came up with a more comprehensive method, that is, first fill the glass jar with food, then gently stopper the bottle with a cork, put it in water and boil for 30 to 60 minutes. Before the food has not cooled down, use a cork stopper to close the bottle mouth tightly, and finally use thread to reinforce the canvas or seal the bottle mouth with wax. In this way, the purpose of preserving food and extending the shelf life can be achieved through the method of re-sealing after high-pressure and high-temperature sterilization and preservation. This was the original food canning technology. Nicolas Appert’s glass canned food is the original prototype of canned food.

Nicolas Appel’s method solved the army food problem encountered by Napoleon. This technology is also widely used in food preservation in the military and nautical future. 

Soon after Nicolas Appert’s glass cans, Peter Durand, an Englishman, began to choose a new material to store food. Instead of Nicolas Appert’s glass bottles, Peter Durand used tin cans. This technology has been passed to the United Kingdom and the United States. Canneries began to spring up on both lands. Canned food as a form of food packaging, has gradually entered people’s lives.After the appearance of the bottle opener, canned food as a form of packaging is more popular than ever before.

During the war, canned food influenced by Nicolas Appert became the army’s first choice. In modern society, the packaging of drinks such as Coca-Cola was also influenced by the Nicolas Appert bottling technology.

It can be seen that Nicolas Appert’s canning technology is a huge change that cannot be ignored for food preservation and even the entire food field.

The R&D team of ECHO Machinery Co., Ltd. pioneered the Vacuum Flatten Packaging Machine MRZK-200P in China.

Advantage

While reducing production costs, MRZK-200P also improves the hygiene standards of the entire line and the efficiency of the packaging line, completely freeing hands and maximizing profits.

MRZK-200P is the first packaging machine with a horizontal vacuum chamber in China. The most traditional material shaping method is to use manual flattening. Too much manual involvement in the production line will cause health and safety hazards. Say goodbye to traditional vacuum chambers and traditional shaping methods, MRZK-200P vacuum processes, and seals materials in the vacuum chamber in a horizontal state. Reduce the participation of personnel on the production line, reduce production costs, improve production efficiency, and maximize profit conversion.

Innovation

The R&D team of ECHO Machinery Co., Ltd. created an original horizontal vacuum chamber, which completely throws away the traditional primitive inefficient method. The machine vibrates and shapes the material in the package in a horizontal state to ensure the overall uniform distribution of materials.

The machine beating replaced the previous manual operation, improved efficiency, and reduced material hygiene and safety risks. We insist on innovation on the road of packaging, considering the needs of customers and consumers. We abandoned the traditional way of pressing the material by hand, the fully automated process runs through the entire production line to reduce the contact between people and materials on the production line. We do not destroy the original form of the material while discharging the air in the packaging.

Before MRZK-200P, 100 degrees vacuum has always been an unachievable standard on the market, but MRZK-200P turns this impossible into a possibility.

A vacuum of 100 degrees is a complete vacuum. Such a vacuum environment is more conducive to the preservation of the items in the package. As far as food is concerned, extending the shelf life of food brings many benefits to both consumers and manufacturers.

The successful development of the horizontal vacuum chamber is an important change in packaging machinery, and vacuum brings a new possibility to packaging.

Sealing process

A good vacuum packaging should be as close as possible to perfection in every detail. Not only the main part where the material is located, but also the sealing treatment should be strictly controlled. Clean seal is the basic, and clean seal is the guarantee of good vacuum packaging effect. After multiple reshaping, the material packaging effect reaches a high standard. Sealing in the vacuum chamber ensures sanitation and safety, and also ensures the vacuum tightness of the packaging. MRZK-200P has carried out more stringent treatment on the packaging seal to ensure that the seal is clean and free of impurity. The sealing of the package treated by the previous semi-automatic vacuum equipment in the past always carried more or less sundries and defects. The seal folding, containing oil and material, etc. are not uncommon. Such vacuum packaging is easy to leak air, increasing the risk of loss. 200P can be smoothed and shaped in one machine, and the finished packaging products are in high quality, which brings new surprises and better experience to consumers.

High-quality accessories

Every time we make unremitting attempts, we hope that we can get satisfactory results. ECHO Machinery’s R&D team leads the industry by discarding additional vacuum accessories and achieve 100 degrees vacuum. MRZK-200P is at the forefront of the industry, creating complete vacuum conditions to extend the storage time limit of materials, making materials safer and consumers more assured. The divider plate of imported material, -0.9 to -0.8 MPa negative pressure suction is more thorough. In addition, the design of MRZK-200P is focused on each user. According to the user’s operating requirements, MRZK-200P is designed with a simple operation interface and one-key operation, even a novice who uses it for the first time can easily get started.

In 2020, the market size of vacuum packaging machines has reached $12.9 billion. In 2025, the market size is expected to reach $16.4 billion, with a compound annual growth rate of 5%. People’s requirements for food storage are increasing, which helps the development of the entire vacuum packaging machinery industry. This is indeed the case.

There are many foods in the market that use vacuum packaging, but due to technical or mechanical problems, the vacuum packaging effect is not particularly ideal. It is not uncommon for materials and grease to be mixed in the seal of the packaging bag, or the packaging seal is folded. With the continuous expansion of the vacuum packaging market, people’s requirements for vacuum packaging have been in an increasingly stringent development and change.

To facilitate transportation and sales of products, flexible packaging is always more selected by food manufacturers in food packaging. Flexible packaging also promoted the innovation of packaging machinery.

The Asia-Pacific region is the main market for vacuum packaging, followed by Europe. In the Asia-Pacific region, with the increase in per capita disposable income, people’s expenditure on food packaging has also begun to increase. More and more health and safety incidents are also updating and improving people’s hygienic standards for food packaging. People always hope that vacuum-packaged food can have better packaging effects and higher packaging quality.

For packaging machinery manufacturers, how to improve packaging quality has also become an important direction of machinery research. A good vacuum packaging machine must not only have a high-quality packaging appearance, but also a good vacuum effect. In addition, how to truly realize 100-degree vacuum packaging is also an important problem to be solved in the field of mechanical packaging.

The reform of food packaging machinery has attracted much attention. The increase in disposable income and the improvement of living standards have caused people to pay more attention to food hygiene and safety, packaging details, etc. The development and production of MRZK-200P is precisely because of the changes and new requirements that people have produced in these aspects.

Winter is coming, the weather is cold, so your factory plans to stop work, but you are worried about the maintenance of packaging machine? Don’t worry, learn our tips right now!

Full cleaning & dust cover

After the work stoppage of the packaging machine, the residual stains on its surface shall be cleaned up comprehensively. At the same time, dust cover shall be used to prevent dust, so that the packaging machine can enter the state faster when it starts work in spring.

Butter the CAM

When shutdown, the cams of the packaging machine frame are coated with good butter, which can not only prevent rust and corrosion, but also reduce the loss of the body when returning to work. We recommend the use of light and thick butter, easy to spread, the effect is better.

Seal the rack & electric box

Close all doors that can be closed, and seal racks and electrical boxes with cloth and foam to prevent rats and other creatures from damaging the wires. We also provide special anti-rat net, effect pull group, customers who need to contact us.

Reinforced circular cup filler

Many customers use our Circular Cup Filler. In our Circular Cup Filler, we use food grade PTFE, which has obvious characteristics of thermal expansion and cold contraction. Therefore, the Cup will loosen in the winter and be fixed with our O-type stiffeners to ensure smooth operation in the coming year.

Empty the water

Our vacuum packaging machine uses the supporting Industrial Chiller. The temperature is too low in winter, and it may freeze inside the machine when it is shut down, so it is not recommended to put it outside for use. When shutdown, it is recommended to empty the internal moisture, so as to prevent low temperature freezing.

Premade pouch protection

In addition to packaging machine, we also need to protect the premade pouch from dust or water accumulation on its surface, which can effectively improve the success rate of packaging and opening.

It’s a dramatic turnaround in the global environmental landscape —— in contrast to the U.S. announcement last year that it was withdrawing from the Paris Agreement. In October, Shinzo Abe announced in National Diet that Japan would achieve carbon neutrality in 2050. On the 28th of the same month, Moon Jae-in also stated that South Korea would achieve carbon neutrality in 2050. With the end of the US election, Biden made it clear that US will rejoin to the Paris Agreement. At the same time, with the impact of COVID-19 on the world, Environmental issues have been raised to unprecedented heights. Technologies such as green energy, recyclable waste, and carbon capture are all actually developing, although we know that such statements in many countries are based on political considerations. 2020 will become an important year in the environmental field. The packaging industry is no exception. In this process, the concept of Green Package is widely spread and accepted.

Standard

As early as 1987, the concept of Green Package was proposed in Our Common Future(also known as the Brundtland report) of the World Commission on Environment and Development. Many countries and regions have also begun to consider environmental factors in packaging standards ——

European Union

The European Parliament and Council Directive has detailed regulations on packaging and packaging waste in 94/62/EC of 1994/12/20. It became a formal law on 1996/6/30, and was revised to 2004/12/EC on 2004/2/11, and its main contents are as follows:

Limits on the content of heavy metal harmful substances: the total amount of lead, cadmium, mercury, and hexavalent chromium shall not exceed 0.01% (100ppm), it is worth noting that this is the basic requirement for each package, we can understand it as the minimum but not the only requirement.

Recycling target of packaging materials: reach 55%～80% by 2008/12/31, the minimum allowable amount of packaging materials recycling is 60% glass, 60% paper, 50% metal, 22.5% plastic, 15% wood. By 2010, the packaging materials will be free of heavy metals and other harmful substances.

United States

There are related regulations in the Toxics in Packaging Prevention Act of the United States. It holds the same views and technical indicators as the EU, and has a buffer on the time gradient. The total concentration of lead, cadmium, mercury and hexavalent chromium in any packaging aids shall not exceed the following regulations:

• Less than 0.06%(600ppm) of weight two years after the entry into force of this Act
• Less than 0.025%(250ppm) of weight three years after the entry into force of this Act
• Less than 0.01%(100ppm) of weight four years after the entry into force of this Act

The purpose of the bill is to reduce harm while promoting the widespread use of recycled materials in packaging and auxiliary products.

China

China’s Food Hygiene Law of the People’s Republic of China stipulates that relevant standards must be met, which includes corresponding specifications for plastics, paper, ceramics, rubber, aluminum products and other materials. It was first stipulated in GB 9683-1988 that the content of heavy metals in 4% acetic acid must be less than 1mg/L. The later GB/T 16716 is the same as ISO 18601 Packaging and the environment.

In addition, in 2019, China also launched the Method and Criteria for Green Packaging Assessment, which stipulates the evaluation method of green packaging, which is divided into four categories: resource attributes, energy attributes, environmental attributes, and product attributes. These include optimization of packaging system, addition rate of recycled materials, water consumption, energy consumption, greenhouse gas emissions, degradation performance and so on.

As the world pays more attention to the environment, the environmental protection requirements of packaging are getting higher and higher. In order to meet the requirements of packaging and the protection of the environment in various countries in the future, we should pay more attention to green packaging.

The establishment of the above standards promoted the development of the industry to a large extent. For the principle of green package, you can read our Packaging Materials Pollute & green Packaging Materials.

Market

It is generally estimated that the current green packaging market is around US$250 billion, and the compound growth rate in the next five years is around 5.5%-6.0%. The Asia-Pacific region has the fastest growth rate, and the current market share in Europe is the highest at around 37%.

There are two main factors that maintain the rapid growth of the green packaging market:

Consumers’ increasing environmental awareness

In the survey conducted by CYCAN, the vast majority of young Chinese interviewed (84%) recognized the seriousness of climate change, and even more than 40% of young Chinese considered it the most serious global problem at the moment, followed by social inequality (12.9%) and public health (8.3%), this investigation is particularly prominent in 2020 when the global epidemic is raging. 95% of the interviewees agreed that “when emitting greenhouse gases, we must consider fulfilling our own responsibilities and being responsible for the future and the next generation.” Only 31.6% of young people believe that “now you don’t have to worry about the energy problems of the next generation.”

More than 50.0% of people in South America and North America like green packaging when buying any product. In addition, 42.0% of respondents expressed their willingness to pay more for green packaging options.

The government takes the initiative to guide the market and introduce relevant laws and regulations

• In July 2019, in order to reduce the pressure on the environment, China launched a new waste sorting program. Courier companies use recyclable boxes, reduce unnecessary packaging, and use biodegradable packaging materials. According to the State Post Bureau, by the end of 2019, it is expected that 95% of delivered packages will use electronic waybills to minimize the use of paper, and this green packaging plan will save the country 207 million single-use plastics each year bag.
• The Australian government has set a goal to adopt 100% recyclable packaging at least by 2025.
• The Netherlands implements an agreement with packaging manufacturers, stipulating that no less than 65% of the packaging materials of the company can be reused, so that the packaging material resources can be recycled to the maximum extent and promote the development of green packaging in the country.
• The United States implements measures such as waste disposal fees and reuse, and vigorously develops pollution-free and easily degradable packaging materials, making the development of green packaging in the United States reach more than 80%.

These actions have led many companies to develop green packaging:

• Nestlé plans to spend up to 2 billion Swiss francs in January 2020 to convert its packaging from virgin plastic to food-grade recycled plastic.
• Coca-Cola promised to collect a can or bottle for everyone that it sells by 2025, to ensure that all its packaging is 100% recyclable, and to ensure that at least 50% of its plastic bottles are from recycled materials.
• Unilever India Co., Ltd. promised to use 100% recyclable packaging by 2025, and has transformed from commercial polymers to performance-based polymers.
• Walmart is committed to reducing the environmental impact of packaging for a long time. Its Sustainable Packaging Manual explains the principles of green packaging from the perspectives of optimized design, sustainable procurement and support for recycling.

There are many such cases, which illustrates the global trend of green packaging. Most companies will have to adopt green packaging in order to maintain an important position in the green packaging market. At the same time, people are more willing to choose green packaging products. Through effective green marketing, users can quickly improve the evaluation of your brand. There is no doubt that Green Packaging will play a very important role in the packaging field in the future. If your company fails to keep up with the development of green packaging, it is likely to be eliminated by the market.

Green Trade Barriers

Green packaging regulations refer to a relatively high and complete packaging material market access system established by developed countries, including standards for waste recycling, reuse and regeneration. It is an environmental protection measure to prevent packaging materials and packaging waste from harming the environment or damaging the health of users.

Green packaging regulations can effectively solve environmental problems and are the best way to achieve the coordinated development of packaging and the environment, It is in line with the world’s environmental protection trend. However, this type of regulation is often used by some countries as a standard for import approval to achieve the purpose of restricting imports and become Green Trade Barriers. Green Trade Barriers have become a trade barrier widely adopted by many developed countries because of its external rationality and internal concealment. If you read the content in the “Standard” of this article carefully, it is easy to realize the existence of green packaging barriers. Under the new situation in the future, we should recognize, understand and solve the problem of green packaging. If you are in a developed country, green packaging can save you from legal issues. If you are in a developing country, green packaging can help you expand your market better and gain market access from developed countries.

Green packaging has many benefits, but it will increase your production costs, but don’t worry too much. The cost of supporting green packaging is very worthwhile, it can increase the value of your brand and avoid unnecessary legal issues. At the same time, green packaging products can have a higher premium, and with the development of technology, the cost of green packaging will gradually decrease. As long as the development trend of green packaging can continue, it will eventually make it the same as the current ordinary packaging. By then, the holy grail of environmentalists —— zero emissions and 100% recycling must not be far away.
