What is PE self-adhesive membrane? Is it the same as PE electrostatic sticker? How to distinguish self-adhesive film from electrostatic sticker?
Hearing this kind of problem, everyone who does the production of protective film feels quite helpless, and the protective film is now fashionable to sell under a new name?
The self-adhesive membrane is actually an electrostatic sticker, just a different name.
In the field of protective film, according to the classification of viscous materials of the protective film, it can be divided into glue-type protective film and self-adhesive protective film, all have their own advantages and disadvantages, self-adhesive protective film is mainly used for high-quality goods, this type of protective film is generally all double-layer above co-extrusion forming, in one of the layers of plastic film using self-adhesive raw materials, and then without sizing strong glue can be self-adhesive. There are many self-adhesive materials, and generally electrostatic stickers use EVA or other modified materials. The basic principle of electrostatic induction self-adhesive is actually because the self-adhesive material belongs to the polymer, the crystallinity is low, and there are many exposed molecular structure chains on the surface of the plastic film, which are very easy to fill the pores on the surface of the attached object, and then bond with each other.
