According to different materials, cling film is mainly divided into two categories:

The first type is polyethylene cling film, PE cling film for short. This material is mainly used for food packaging. Fruits, vegetables, and food semi-finished products are usually packaged in this kind of cling film.

The second type is PVC cling film for short. This material can also be used for food packaging, but it has a certain impact on the safety of the human body.

There are certain differences between PE cling film and PVC cling film. Both types of cling film are colorless and transparent. Generally, the most direct identification method is to identify through the outer packaging of the cling film.

The appearance of PVC cling film is more transparent than PE cling film, and it will emit black smoke after ignition and burning without dripping oil. On the contrary, after the PE cling film is ignited and burned, it will not have a strange smell and will drip oil.

PE cling film can be used for microwave heating. Due to the different properties of raw materials, PE cling film is more resistant to high temperatures. Many microwave ovens have different fire power adjustments. When cooking in a microwave oven, as long as you make sure that you are using PE cling film, you don`t have to worry about harmful substances.
