Definition:

Food packaging roll film is a packaging film supplied in rolls, food packaging roll film is applied to automatic packaging machinery, no packaging production enterprises to seal the edge work only in the production enterprise to carry out a one-time edge operation. The advantage is to save the cost of the entire packaging process.

On the food packaging film material, its material type is consistent with ordinary food packaging bags, common PVC film, opp film, pe film, pet film, pa composite film and so on. The details are as follows:

1, PE food packaging film

Polyethylene, referred to as PE, is a polymer organic compound made of ethylene, which is recognized as a good material for contact with food. Moisture-proof, anti-oxygen, acid-resistant, alkali-resistant, tasteless, odorless, in line with food packaging hygiene standards, known as “plastic flower” reputation.

2, PO food packaging film

PO is a polyolefin copolymer, which is a polymer obtained from an olefin monosystem. Opaque, brittle texture.

3, PP food packaging film

PP is a kind of thermoplastic, which generally uses color printing, offset printing process, bright color, is a tensile polypropylene plastic, environmental protection, tasteless, smooth and transparent surface.

4, OPP food packaging film

OPP is polypropylene, bidirectional polypropylene, which is characterized by easy combustion, melting dripping, yellow and blue, less smoke after the fire, continue to burn. It has the characteristics of high transparency, brittleness, good sealing and strong anti-counterfeiting.

5, PPE food packaging film

PPE plastic packaging bag is a combination of PP and PE products, the product has the characteristics of dust, bacteria, moisture, oxidation resistance, temperature resistance, oil resistance, environmental protection and tasteless, high transparency, strong mechanical properties, high blasting resistance, puncture resistance and tear resistance. Automatic packaging machine roll film is an important industrial supplies, mainly used for packaging food, medicine, daily necessities and other products. It is usually composed of a drum material, a transmission device, a heat sealing device, a cutter, etc. In the automatic packaging machine, the material, thickness, air permeability and other parameters of the roll film will affect the packaging effect and product quality. Therefore, choosing the right roll film is very important for both manufacturers and consumers.

The material of automatic packaging machine roll film is generally plastic, aluminum foil and so on. Among them, the plastic roll film has the advantages of high transparency, good barrier, etc., but it also has the disadvantages of low strength and easy tearing. Aluminum foil roll film has the advantages of high strength, good barrier property and long shelf life, but it also has the disadvantages of high cost and non-degradation. Therefore, when selecting the automatic packaging machine roll film, it is necessary to comprehensively consider the characteristics and needs of the product.
In addition to the material and thickness, the air permeability of the automatic packaging machine will also affect the packaging effect. If the permeability of the roll film is not good, it will lead to the gas in the package can not be discharged, so that the product deteriorates or affects its taste. Therefore, when selecting the automatic packaging machine roll film, it is necessary to choose a roll film with good air permeability.
In short, automatic packaging machine film is an indispensable part of modern industrial production. Choosing the right film can improve the quality of the product, but also can reduce production costs and improve production efficiency. Therefore, manufacturers in the selection of automatic packaging machine roll film need to carefully consider its material, thickness and permeability and other factors to choose what material roll film.
