Supermarket special plastic wrap purchase method
- Oct 18, 2018 -

When buying a special wrap film for supermarkets, it is recommended to buy a self-adhesive wrap film made of polyethylene material, especially when preserving meat, fruits, etc., because of the safety, PE cling film is the safest. It can guarantee the freshness of various foods.  


 If you want a longer shelf life, it is recommended to choose a special plastic wrap for polyvinylidene chloride supermarkets. Because the moisture retention performance of this material is better, the shelf life of the three kinds of plastic wrap is the longest. Polyvinyl chloride-based supermarket special wrap film, because of its good transparency, good viscosity, good elasticity, and relatively cheap price, has become a choice for many people, but it must be noted that it cannot be used for the preservation of fatty foods.


  Because it is a resin composed of a polyvinyl chloride resin, a plasticizer and an antioxidant, it is not toxic by itself. However, the main auxiliary materials such as plasticizers and anti-aging agents are added. The plasticizers in daily-use polyvinyl chloride plastics mainly use dibutyl terephthalate and dioctyl phthalate. These chemicals It is toxic, and the oil in the food is easy to dissolve the plasticizer "ethyl ammonia" in the plastic wrap, which has a great destructive effect on the human endocrine system and will disturb the body's hormone metabolism.
