Generally speaking, PVC cling film is not suitable for use in food packaging because it contains a large amount of plasticizers. When used under heating or in contact with oily food, the plasticizers contained in PVC cling film are prone to precipitation, which can cause certain harm to the human body and even cancer as food enters the body. But we also found that these adverse effects have not completely led them out of our lives. What is the reason for this?

Guess 1: Compared to PE film, it has more significant advantages

The speculation about this is based on a comparison between these two materials. For example, compared to PE film, PVC film has better transparency and greater tensile force. In addition, good self adhesion is also one of its advantages. Speculation 2: Higher cost-effectiveness

PVC plastic wrap is mainly used for food packaging in the fresh and bulk food areas of supermarkets. In addition, various hotels, restaurants, and other group customers purchase and use PVC more. Due to its cheap price, PVC has a large market share, reaching 60% to 70%. This cost-effectiveness advantage has led to the circulation and use of a large number of PVC products.

Perhaps due to the influence of the above two reasons, PVC plastic wrap has not been completely prohibited. Of course, if it is not heated or operated on, its harm is still relatively small, but we hope everyone can use it with caution.
