The industry's favor. However, due to the difficulty in forming PVC heat shrinkable film, it is necessary to add a large amount of

Plasticizers, plasticizers and vinyl chloride in heat-shrinkable films under high temperature and grease conditions

The monomer will dissolve and cause potential health hazards to consumers. In addition, due to PVC heat shrinkable film

It is difficult to recycle after being discarded, and it cannot be incinerated (easy to produce strong carcinogen dioxins

And acid gas hydrogen chloride). So, from saving resources, protecting the environment and eliminating
