The release film refers to the film that can be distinguished on the surface of the film. The release film does not have viscosity or slight viscosity after contacting with specific materials under limited conditions.

The heat-shrinkable film is used for the sale and transportation of various products, and its main function is to stabilize, cover and protect the products. The shrinkage film must have high puncture resistance, good shrinkage and certain shrinkage stress. During the shrinkage process, the film can not produce holes. Because the shrink film is often suitable for outdoor use, UV anti-ultraviolet agent needs to be added.

Ordinary PET is a crystalline polymer. After the PET film is stretched and oriented, it will produce a large degree of crystallization. If it is heat sealed, it will produce shrinkage deformation. Therefore, ordinary PET film does not have heat sealing performance.
