PE shrink film formula is the main component of polyethylene, followed by silica, antistatic agent, pigment, anti-ultraviolet agent. Shrink films are mainly stressed films and have certain applications in food, medicine, stationery, and another packaging.
PE heat shrink film test Polyethylene is the main component of shrink film. Polyethylene is composed of many vinyl monomer polymer compounds. Polyethylene is chemically stable, easy to age, easy to degrade, and does not generally react with oxidants.
Silica can be added to the shrink film formulation uniformly, which can increase the shrinkage and smoothness of the film. On the other hand, it can also increase the toughness of the shrink film to change the tensile strength of the shrink film. Silica also has an anti-ultraviolet effect, prevents polyethylene from degrading polyethylene, and delays the aging of shrink films.
