What's The Difference Between Household Plastic Wrap And Wrapping Film?

Plastic wrap is a kind of winding film, but because it does not need as high as the self-adhesive properties of winding film, so the use of polyisobutylene will be less, polyisobutylene is mainly used to increase the product flexibility and self-adhesive.

Plastic wrap is a kind of plastic packaging products commonly used to keep fresh food. At present, the plastic wrap on the market mainly includes: the first kind is polyethylene, this material is mainly used for food packaging, such as fruits, vegetables and so on, including semi-finished products purchased in the supermarket are used in this material;

The second is polyvinyl chloride, which is also used in food packaging. The third is polyvinylidene chloride, mainly used in some cooked food packaging. Because the plasticizer used in PVC plastic wrap has carcinogenic effect, and the production cost of PVDC is too high, so most of the domestic plastic wrap is inclined to use PE as raw material.
Wrap film, also called stretch film, heat shrink film, PVC as the base material, DOA as a plasticizer and self-adhesive production of PVC wrap film earlier in China. Due to environmental problems, high cost (relative PE ratio is significant, the unit packaging area is small), poor tensile property and other reasons, when the domestic production of PE stretch film began in 1994 ~ 1995, it was gradually phased out. PE tensile film first used EVA as self-adhesive material, but its cost is high and it has a taste. Later, PIB and VLDPE are developed as self-adhesive materials. Now LLDPE is the main base material, including C4, C6, C8 and metallocene PE(MPE). Use plastic wrap when packing food that can be touched. When wrapping items, use wrap wrap.
