Experts recommend PVC shrink film is not suitable for food packaging

PVC heat shrinkable film is not environmentally friendly. It is widely used in the packaging industry due to its waterproofness, flame retardancy, relatively low cost, and high yield. However, according to experts, due to the difficulty in forming PVC heat shrinkable film, it is necessary to add a large amount of plasticizers. Under the environment of high temperature and grease, the plasticizer and vinyl chloride monomer in the heat shrinkable film will dissolve out, causing consumer health problems. Hidden danger. In addition, PVC heat shrinkable film is difficult to recycle after being discarded, and cannot be incinerated (easily produces strong carcinogen dioxins and acid gas hydrogen chloride). Therefore, some experts believe that from the perspective of resource conservation, environmental protection and consumer safety, it is considered that PVC heat shrinkable film is not suitable for food packaging.
