Protective film is more common in daily life, such as newspapers, magazines and other printed materials that we come into contact with every day, furniture such as dining tables and desks, kitchen supplies such as stainless steel cabinets, decoration materials such as marble and flooring, and some fresh food Waiting for the surface of the object, etc., it can be said that we will come into contact with it everywhere in our lives. Its function, as the name suggests, is to protect our items from sunburn, scratches, corrosion, waterproof, moisture-proof, and freshness.
The protective film is divided into PP material, PVC material, AR material, OPP material and PE material according to the material. PP material appeared on the market in the early stage. Because it has no adsorption capacity and requires glue to stick, it is easy to leave traces of glue and is gradually eliminated by the market. PVC material, its characteristic is that the material feels soft, but the material is relatively thick, the light transmission is poor, and the color will turn yellow after long use. AR material is a synthetic material with strong resistance to friction and scratching, and does not need to be glued. PE material, soft material with certain elasticity and stretchability, good light transmission, and more beautiful. Depending on the material, the purpose is different. For example, PE material is mainly used for aluminum plates, films, glass plates in the printing industry, hardware industry, wire and cable industry, and some semi-finished products that need to be rolled and packaged. AR material is mainly used for screen protection.
