Is PE plastic wrap resistant to high temperature?

Cling film is a kind of plastic packaging product, usually made of ethylene as masterbatch through polymerization reaction. Cling film can be divided into three categories: the first is polyethylene, referred to as PE; the second is polyvinyl chloride, referred to as PVC ; The third is polyvinylidene chloride, referred to as PVDC. Today we will focus on the introduction of PE plastic wrap.

The PE plastic wrap is mainly used for food packaging. This film is used for the fruits and vegetables we usually buy, including the semi-finished products purchased in the supermarket.

From a physical point of view, the plastic wrap has moderate oxygen permeability and moisture permeability, which can adjust the oxygen and moisture content around the fresh-keeping product, block dust, and prolong the fresh-keeping period of the food. Therefore, it is necessary to use different plastic wrap for different foods.

PE plastic wrap has poor heat resistance and should not be used at high temperatures. If PE plastic wrap is used outside the temperature range, it will cause the material to decompose into food, which is harmful to the human body, so it is best not to heat it. In addition, according to relevant regulations, if it can be used for microwave heating, it will be marked on the package that it can be used in microwave ovens.

We usually buy fruits and vegetables back, and we can wrap them in PE plastic wrap and put them in the refrigerator, but this kind of plastic wrap has poor heat resistance and is usually not suitable for use at high temperatures. According to experts, the use of pe cling film outside the temperature range may cause the material to decompose and dissolve into the food, which will cause harm to the body after eating.
