What are the Packing Types Options of a Food Packing Machine?

Food packing machines can provide the following packaging types:

• 3 or 4 sides flat sachet
• Doypack
• Top spout sachet
• Pouches
• Bottles
• Bags
• Special-shaped bags
• Stand bag
• Zipper bag
• Flat bag

Cushion bag： It may be classified into two varieties based on the closure mechanism: overlapping longitudinal seam bag and overlapping longitudinal seam side folding bag.

There are three sides sealed pockets in flat bags and four sides sealed pockets.

Freestanding bags: It includes pointed corner bags, oval cylinder bags, triangular bags, and cubic cylinder bags.

During the production process, bags are normally sealed longitudinally and horizontally. As a result, three or four layers of films are overlapped in the sealing part of the flap and the butt sealing seam of the cushion bag, which reduces the sealing quality. The inner film of the three-sided flat sealing bag has an equal number of layers, and the sealing quality is excellent. Nevertheless, the bag’s shape is asymmetrical, and the aesthetics are poor.

The four-sided seal makes it possible to overcome the disadvantages of the two preceding situations. However, packaging materials are used more frequently. Various freestanding bags have attractive designs and the ability to stand without falling, which is important for future packaging operations and product positioning and presentation. However, composite packaging materials should be used as the packaging materials must meet a series of criteria.

What Packing Materials Can You Use in a Food Packing Machine?

You can use different materials such as:

• PE compound materials
• Aluminum foil
• Single-PE
• CPP composite materials; and more

What is the Filling Speed of a Food Packing Machine?

The filling speed of a food packing machine depends on the packaging type and packaging size.

How are Food Packing Machines Constructed?

A food packing machine is commonly built using stainless steel 304 and 316 materials.

Most food packing machines have different capacities, power, sizes, weight capacity, and more.

It is also composed of different parts such as a platform, combination weigher, Z-type conveyor, vibration feeder, collection table, and more.

Different types of food packing machines are built according to international standards. Since these machines are used in a wide range of food and beverage industries, they should conform to hygiene and safety standards.

What are the Typical Applications of a Food Packing Machine?

It is also used for packaging fresh fruits and frozen foods like meat, seafood, and more.

Most food packing machines are also used for packaging water bottles, sodas, and more.

What are the types of food packing machines？

A small food packing machine is multifunctional packaging equipment. It uses heat-sealed flexible packaging materials to automatically complete bag making, material measurement and filling, exhaust or inflation, sealing, and cutting. It can be used to package liquid, solid, and gas materials.

It is a packaging machine with the fastest development and the most extensive application. The solid line is the basic operation procedure, and the dotted line is the auxiliary working procedure.

There are two types of packaging machines: pillow and vertical.

Due to the wide variety of bag shapes, the type and structure of bagging machines are also quite different, mainly reflected in the bagging and sealing device. The equipment for producing film bags is called a bagging machine, which mainly has two types: vertical and pillow.

• Vertical bagging machines can be divided into a bag-making machine and a direct moving bag-feeding bagging machine.

The bag-making bagging machine is suitable for producing pillow bags, three sides sealed bags, four sides sealed bags, flat bags, and self-supporting bags. Different bag shapes can be divided into:

the lapel forming bag-making machine is used to produce pillow bags. It can complete the bag making, longitudinal sealing (overlapping or docking), charging (filling), sealing, and cutting plastic films.

• tower and cubic column bag making small food packing machines

The machine is mainly used for filling and packaging liquid drinks. The packaging container is in tower shape and cubic shape.

• Vertical small food packing machines are mostly used for bag making, filling (filling), and sealing liquid drinks.
• Pillow food packing machine is mostly used for packaging biscuits, pastries, instant noodles, popsicles, ice cream, and other massive materials.

What is the pillow food packing machine?

Pillow food packing machines are used for packaging materials such as paper, aluminum foil, plastic film, and composite film.

It is a kind of processing to packing block materials by folding, sealing, and kinking equipment. According to the shape and nature of materials and different packaging requirements, there can be different materials 、different wrapping shapes.

1. The end folding pillow type food packing machine uses the method of end edge corner folding to wrap, such as biscuits, bread, the packaging of cigarettes, etc., shall be bonded or heat sealed after corner folding to prevent loosening.

2. The twisted pillow food packing machine uses the packaging material to wrap the material. Then, the extended part’s packaging material is rotated and twisted together to complete the wrapping. Which can be divided into two end twisting types .it. Can single-end twisted types (ice cream, etc.).

3. Adhesive pillow-type food packing machine consists of two layers of packaging materials to clamp the materials and bond them together.

4. Heat-shrink pillow packaging is wrapped with heat shrink materials. Then heated to make packaging materials shrink to achieve the Purpose of wrapping materials.

What is the Purpose of vacuum food packing machines？

For foods that are easy to oxidize and deteriorate, metal products that are easy to oxidize and rust, plump down, and vacuum packaging can be used for cotton and hemp. The Purpose of vacuum packaging is:

① Remove the air to prevent bacteria from multiplying, causing food corruption, or preventing metal oxidation and rust;

② It is convenient for heating and sterilization after sealing to prevent air expansion from cracking the package;

③ Reduce the volume of bulky articles, facilitate storage and transportation, and save costs;

④ Prevent food oxidation and deterioration.

Other inert gases, such as carbon dioxide and nitrogen, can be filled after vacuuming, called inflatable vacuum packaging, to protect the contents and prolong the shelf life.

What are the Causes of wrinkling in the horizontal sealing of the food filling machine？

The main function of the horizontal seal of the food filling machine packaging equipment is to seal the horizontal side of the packaging bag. Similarly, whether it is a back seal, three side seal, or four side seal, the horizontal seal is heated and sealed by the horizontal seal device. The horizontal and vertical seals are used together to seal a beautiful packing bag. When the packaging machine is working, the film will inevitably wrinkle, so what is the reason for the wrinkle of the cross seal?

1. The film pressing clearance of the transverse sealing cutter of the packaging machine is uneven, resulting in uneven stress on the packaging film.

2. The transverse sealing temperature of the food filling machine is too high, or the heating of the sealing knife is uneven.

3. The included angle between the cutting knife at the transverse seal and the packaging film is not vertical, resulting in wrinkling.

4. It is caused by the inconsistency between the speed of the transverse sealing cutter and the tensile speed of the food filling machine film.

5. The feeding speed of the equipment is inconsistent with the film pulling speed, resulting in the material in the transverse sealing position and the wrinkling of the packaging bag.

6. The heating pipe is installed unevenly, and foreign matters are stuck at the transverse seal, affecting the packaging quality.

7. The food filling machine film itself has problems and is unqualified.

8. The sealing pressure of the packaging machine is too high.

What is the difference between a roller food packing machine and a splint food packing machine?

When consumers buy packaging machines, they are often asked by manufacturers do they want to buy roller food packing machines? Or splint food packing machine? So what is a roller packaging machine? What is a splint packing machine? Today we will introduce the difference between the two machines.

Both machines belong to the roll film packaging machine. The roller packaging machine has obvious advantages in making liquid sauce and other liquid materials. When making powder particles and other materials, the price of the splint packaging machine is lower. Consumers can tolerate the leakage of powder particles. The splint food packing machine now has more advantages.

1. Sealing form

The splint food packing machine adopts face-to-face contact sealing. Which can not ensure the uniform distribution of pressure on the four sides of the packaging bag when the splint food packing machine is making the bag. Which will lead to the low compressive capacity of the product and an increase in the probability of air leakage in the bag during long-distance transportation.

The roller food packing machine adopts line contact sealing. The line (point) contact sealing can ensure that the temperature and pressure of the roller are stable during bag making. The roller runs at an average speed. The sealing pressure on the four sides of the packaging machine is the same.

When pressed, the pressure is evenly distributed at each point on the bag. When the product is under the same pressure, the surface contact type has a greater probability of penetration than the line contact type.

2、 Packaging form

The splint food packing machine only needs a pair of splints when making three side sealing products. Still, when making four side sealing products, a product needs a pair of splints, which is inconvenient to adjust when changing products. Moreover, the splints and scissors are tens of thousands of times a day.

Due to their specific fixing method, the screws of the splints on the fixing frame will become loose, resulting in the dislocation of the concave splints when closing the convex splints, and the scissors do not cut the products, resulting in the unqualified packaging of products, The rate of damage of the rigid splint is increased;

The roller food packing machine does not have this problem. A pair of rollers for anyone / three / four / side sealing products between 1-60g can meet the production. The design of cutting, sealing, and incision is reasonable, and the operation is stable and reliable.

The roller is fixed by automatic bearing, and the natural circular rotation is done during production. So there are no problems caused by the long-time production of the splint food packing machine.

3、 Heating mode

The splint food packing machine adopts a conduction (contact) heating mode, which can not be completely cut off when cutting off the power supply of the heater and is difficult to control;

The heating mode during hot compress can completely cut off the heating source when cutting off the heater’s power supply. So the temperature drift is small and generally within ± 1 ℃.

Packaging materials have high requirements for the stability of temperature. Because the inner materials of packaging materials are different, the melting point temperature is different. However, the melting point temperature has the advantage of a fixed value.

If the temperature is too high, the packaging material will deform severely. Suppose the temperature is too low and can not reach the melting point. The packaging material can not be heat sealed reliably, and the bag is not sealed tightly. In machine production, the defect rate and waste are also directly related to the temperature.

4、 Transmission mode

The cam of the splint food packing machine’s camshaft transmission machine works tens of thousands of times under great resistance every day. Even if the angle changes a little, the work of each link will be abnormal. Therefore, the power comes from one shaft and the cam on the shaft, and the space is narrow, the maintenance remains unchanged, and the failure rate is high.

The chain drive of the roller food packing machine has much smaller relative transmission resistance, more useful work, reliable transmission, high efficiency, and high reliability.

5、 Price difference

The machine shell of the splint food packing machine adopts a plastic spraying treatment, with a relatively simple structure, fewer materials, and low cost. Hence, its price is more acceptable, which is also the biggest advantage of the splint food packing machine.

According to different configurations, the market price of a roller food packing machine will make some start-up enterprises feel high in terms of price. However, in terms of long-term benefits, the service life of the roller machine (5-10 years or more) is much longer than that of the splint food packing machine, with a low failure rate and simple maintenance.

Therefore, saving consumables, packaging materials, materials, manpower, material resources, and cost-sharing from the output perspective. The benefits brought by the roller machine to customers are that the longer it is used, the greater the benefits it will bring. The more it can reflect its value.

Pillow food packing machine is used for packaging materials such as paper, aluminum foil, plastic film, and composite film.

It is a kind of processing to packing block materials by folding, sealing, and kinking equipment. According to the shape and nature of materials and different packaging requirements, there can be different types of materials 、different wrapping shapes.

1. The end folding pillow type food packing machine uses the method of end edge corner folding to wrap, such as biscuits, bread,the packaging of cigarettes, etc shall be bonded or heat sealed after corner folding to prevent loosening.

2. The twisted pillow food packing machine uses the packaging material to wrap the material. Then the packaging material of the extended part the materials are rotated and twisted together to complete the wrapping. Which can be divided into two end twisting types .it can single-end twisted types (ice cream, etc.).

3. Adhesive pillow-type food packing machine consists of two layers of packaging materials to clamp the materials and bond them together.

4. Heat-shrink pillow packaging is wrapped with heat shrink materials. Then heated to make packaging materials shrink to achieve the purpose of wrapping materials.
