Many people think that Clear Self Adhesive Film are different from electrostatic membranes, but their understanding is wrong. In the protective film industry, according to the classification of the viscous material of the protective film, it can be divided into glue type protective film and self-adhesive protective film. Each has its own advantages and disadvantages. PE self-adhesive film is mainly used for products with higher appearance quality. The protective film is generally multi-layer co-extrusion molding, and the film of one layer is made of self-adhesive material, so that it can be self-adhesive without coating glue. PE self-adhesive film is a new type of packaging material with simple production process. The film can be used for manual packaging or mechanical packaging, and the operation is convenient and simple. PE self-adhesive film has good physical and chemical properties. A good PE self-adhesive protective film has few crystal points, good ductility, waterproof, dustproof, high transparency, excellent temperature resistance, non-toxic, odorless, safe and environmentally friendly. Widely used in hardware products, plastic products, optoelectronic products, etc. The similar electrostatic film is also a kind of self-adhesive film. It has low adhesion and is sufficient for high-gloss surfaces. It has the function of non-adhesive and self-adhesive. It is an excellent high-end glossy film that adheres to the product itself by electrostatic adsorption. Items that play a protective role are generally used for surfaces that are more sensitive to adhesive or glue residue, and are mostly used for very smooth surfaces such as glass, lenses, high-gloss plastic surfaces, and acrylic.
