Factors affecting Self Adhesive Protective Film

- Sep 25, 2020-

There are many factors that affect PE self-adhesive film. The first point is the crystallinity of the PE material. The lower the crystallinity, the better the adhesion, and the higher the crystallinity, the worse the adhesion. Crystallinity reflects the density of PE material from another angle. The second point is related to the flexural modulus of the PE material. The flexural modulus represents the softness of the PE material. The lower the flexural modulus, the softer the PE protective film, and the easier it is for PE low molecules to penetrate the surface of the object. The affixed object fits more firmly.
