Food packaging rolls are a kind of packaging film supplied in rolls; food packaging rolls are used in automatic packaging machinery, without the need for packaging production enterprises to carry out sealing work only need to carry out a one-time sealing operation in the production enterprises. The advantage is that it saves on the cost of the whole packaging process.

　　About the food packaging rolls of film material, its material type and ordinary food packaging bags are consistent, as well as standard PVC film, opp film, PE film, pet film, pa composite film, and so on. Details are as follows:

1, PE food packaging roll film

　　Polyethylene, PE for short, is a polymerization of ethylene into a polymer organic compound recognized as a promising material for contact with food. Moisture, oxygen, acid, alkali, tastelessness, odorlessness, and in line with food packaging hygiene standards are known as the “flower of plastic” reputation.

2. PO food packaging roll film

　　PO, a polyolefin copolymer, is a polymer produced by the olefin monomer—opaque, brittle texture.

3. PP food packaging film

　　PP is a thermoplastic plastic generally used in colour printing, offset printing, and bright colours. It is a tensile polypropylene plastic with environmental protection and an odourless, smooth, and transparent surface.

4 . OPP food packaging film

　　OPP is polypropylene, bidirectional polypropylene, which is characterized by being easy to burn, melt, and drip. On the yellow and blue, away from the fire, it produces less smoke and continues to burn. It is also characterized by high transparency, brittleness, good sealing, and strong anti-counterfeiting.

5 . PPE food packaging roll film

　　PPE plastic packaging bag is a combination of PP and PE production the product; the product is dust-proof, anti-bacteria, moisture, oxidation, temperature resistance, oil resistant, environmental protection and tasteless, high transparency, strong mechanical properties, high resistance to bursting performance, puncture resistance and tearing performance and so on. Automatic Packaging Machine Roll FilmAutomatic Packaging Machine Roll Film is an essential industrial supply, mainly used for packaging food, medicine, daily necessities and other products. It usually consists of roll material, transmission device, heat sealing device, cutter, etc. In an 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 proper roll film is essential for manufacturers and consumers.

The automatic packaging machine roll film materials are generally plastic, aluminium foil, etc. Among them, plastic roll film has the advantages of high transparency, suitable barrier properties, etc., but at the same time, there are also shortcomings, such as low strength and ease of tear. Aluminium foil roll film has the advantages of high strength, good barrier properties, and long shelf life, but there are also shortcomings such as high cost and non-degradable. Therefore, when choosing automatic packaging machine roll film, comprehensive consideration needs to be made according to the characteristics and needs of the product.

In addition to material and thickness, the permeability of automatic packaging machine roll film will also affect the packaging effect. If the permeability of the roll film is not good, it will lead to the gas inside the package not being discharged, so the product deteriorates or affects its taste. Therefore, when choosing automatic packaging machine roll film, you must choose the film with good air permeability.

In short, automatic packaging machine roll film is an indispensable part of modern industrial production. Choosing the right roll film can improve the quality of the product, reduce production costs, and improve production efficiency. Therefore, manufacturers need to carefully consider the material, thickness, permeability, and other factors when choosing automatic packaging machine film.
