Wrapping film has high tear strength, high tensile strength, and transparency, but it cannot be used for food packaging. Plastic wrap Transparent, food grade, can be packaged foods, slightly less tensile strength, plastic wrap expensive.
Stretch film, also called elastic film, is mainly used in industry. When it is used, it can utilize the self-adhesive elastic stretch winding of the film itself, wrap the goods tightly by the viscoelasticity of the film surface and the pulling tension used during use, so as to achieve the purpose of protecting the goods.
Plastic wrap is a kind of plastic packaging product commonly used by people for fresh food preservation. It is a type of wrapping film, but because it does not require high self-adhesive properties like a stretch film, the use of polyisobutylene will be less, polyisobutylene Mainly used to increase product flexibility and self-adhesion. At present, there are mainly three kinds of plastic wraps on the market. The first type is polyethylene. This material is mainly used for food packaging, such as fruits, vegetables, etc., including semi-finished products purchased in supermarkets. The species is called polyvinyl chloride. This material can also be used for food packaging. The third type is polyvinylidene chloride, which is mainly used for packaging of cooked foods. Since plasticizers used in PVC cling film are carcinogenic and PVDC production costs are too high, most cling films tend to use PE as a raw material.
