PE Shrink Film Composition

The main ingredient in PE shrink film formulation is polyethylene, followed by silica, antistatic agents, color, UV resistant agents, etc.Shrink film is mainly a kind of film with the role of stress, in food, medicine, stationery and other packaging applications.

PE: PE shrink film test out polyethylene is the main component of the shrink film, polyethylene is a compound made from the polymerization of many ethylene monomers, it is non-toxic, tasteless is widely used in food, pharmaceutical packaging plastics, polyethylene has a stable chemical properties, not easy to aging, easy to degradation, do not react with general oxidants and other characteristics.

Silicon dioxide can be uniformly added to the pe shrink film formula can increase the denseness and finish of the PE shrink film, on the other hand, can also enhance the toughness of the shrink film, change the tensile strength of the shrink film. Silicon dioxide also has anti-ultraviolet efficacy, can prevent ultraviolet degradation of polyethylene, delay the aging of shrink film.

PE shrink film test found that the main non-ionic antistatic agent is ethoxylated aliphatic alkyl amine, which is a wide range of use, can be maintained for a long time antistatic effect of antistatic agent. Nonionic antistatic agents have the advantages of good dispersion, easy transportation, and good processing performance.

Pe shrink film formulations in the anti-ultraviolet agent is mainly able to convert light energy into heat, to avoid degradation of plastics in the ultraviolet radiation, commonly used ultraviolet absorbers are mainly benzophenone and benzotriazole.
