It is well received by users. Shrink films are divided into PE heat shrink film, PVC film, POF, OPS shrink film, PET heat shrink polyester film, etc. Each classification is applied in different places.
 

Application of heat shrink film:
1. Shrink film is used for the sales and transportation of various products. Its main function is to stabilize, cover and protect the product. The shrink film must have high puncture resistance, good shrinkage and certain shrinkage stress. During the shrinkage process The film must not have holes.
