Household plastic wrap purchase requirements
- Aug 14, 2018 -

When using the plastic wrap and the plastic wrap, it is necessary to pay attention to whether it is marked with a specific name or chemical structure. The crisper mainly has two types of materials: polyethylene (PE) and polypropylene (PP). The price difference between products is not large, but polypropylene (PP) can better prevent the penetration of oil.

When buying plastic wrap, it is first necessary to purchase a self-adhesive cling film made of polyethylene, especially when it is used for preserving meat, fruits, etc., because of safety, PE material. Cling film is the safest. If you want a longer shelf life, it is recommended to choose polyvinylidene chloride (PVDC) because the cling film of this material has better moisturizing performance and the longest shelf life in the cling film of the three materials.

The PVC film is mainly made of transparency, good viscosity, good elasticity and relatively low price. Therefore, it 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, and is not toxic by itself. However, the main auxiliary materials such as plasticizers and anti-aging agents added are toxic, and plasticizers in daily-use polyvinyl chloride plastics mainly use dibutyl terephthalate or dioctyl phthalate.
