Background

The surface protection adhesive tape is mainly used for protecting the pressure-sensitive adhesive tape on the surface of a material, and can prevent the surface of the material from being scratched, polluted, corroded and the like in the processes of processing, transportation, storage and use. According to statistics, the annual demand of the domestic surface protective film reaches 12 hundred million m2, and the surface protective film is an important variety of pressure-sensitive adhesive products; the application field of the surface protection film also relates to the industries of building materials, electronics, automobiles, furniture, electric appliances and the like, and can be widely used for sticking and protecting the surfaces of various high-finish materials such as stainless steel plates, aluminum alloy decorative plates, labels, organic glass, high-grade building materials and the like.
