The difference between stretch wrap film and protective film
PE stretch stretch film is an industrial product with high tensile strength, high elongation, good self-adhesiveness, and high transparency. It is used for manual wrapping or wrapping, or machine wrapping and wrapping. This product is widely used in the centralized outer packaging of various goods. The difference between stretch stretch film and protective film products is as follows: 1. The material is the same, but the process is different: Stretch stretch film is a product made of PE polyethylene material, which is a material with strong toughness. product. The main material of the protective film is made of ethylene as the masterbatch through polymerization reaction. According to the different materials used and the addition of plasticizers, the protective film is divided into various types, which can be applied to different occasions. For example: according to the purpose, the protective film can be divided into digital product protective film, car protective film, household protective film, food fresh-keeping protective film, etc. 2. Different uses: Stretch stretch film products are mainly used for wrapping protection in the sales and transportation of alcohol, cans, mineral water, various beverages, cloth, non-food, pharmaceuticals and other products effect. The protective film is mainly used in microwave food heating, refrigerator food preservation, fresh and cooked food packaging, etc., in the field of food packaging in family life, supermarkets, restaurants and industrial production. 3. The starting point of product environmental protection is different: The material PE of the stretch stretch film can reduce air pollution, reduce the amount of waste treatment, recycle, and reduce the overall packaging cost and other advantages. Some manufacturers use PVC materials in the production of protective film products, and this plasticizer is easy to seep from the plastic wrap products into the high-fat food in the package at room temperature or under heating, thus causing certain harm to the human body.
