1.At present, there are three main types of cling film: PE, PVDC and PVC. Among them, PVC cling film is listed as a restricted category by the country because of its plasticizer, and it is stipulated that "meat, cooked food and oily food cannot be directly packaged".
2.To draw PVC into a transparent and soft cling film, a large amount of plasticizer needs to be added. The plasticizer is soluble in oil. When it is in contact with oily food or containers for a long time or under high temperature, it will easily ooze out, and it will accumulate for a long time. It is harmful to the human body. If the vinyl chloride monomer in the PVC cling film exceeds the national standard range, it is more likely to cause cancer. Therefore, this PVC cling film should be used as little as possible.
