is a functional film product based on BOPP. One side is coated with acrylic glue, and the other side is bonded with a release film (single layer non-adhesive release film). It is a very important flexible packaging material. It has the advantages of smooth and transparent film surface, high transparency, good temperature resistance and weather resistance. It is colorless, tasteless, tasteless and non-toxic, with good tensile strength, impact strength, rigidity and toughness. BOPP film has low surface energy and needs corona treatment before gluing or printing. The BOPP film after corona treatment has good printing adaptability and can be printed in color to obtain a good appearance effect, so it is often used as the surface material of the composite film. The main purpose: Hardware industry: computer case, galvanized sheet stamping, aluminum sheet, stainless steel sheet, titanium sheet, plastic steel sheet, glass sheet, solar panel, etc. Optoelectronics industry: liquid crystal displays, backlight panels, cold light films, membrane switches, mobile phone screens, etc. Plastic industry: ABS, OPP injection products, PVC boards, acrylic boards, instruments, plastic lenses, surface protection of painted parts, etc. Printing industry: surface protection of printed nameplates such as PVC, PC board, aluminum board, film, etc. Wire and cable industry: protect shaft-mounted copper wires, semi-finished products, finished products and rolled products, can effectively prevent dust pollution, and have anti-oxidation and anti-fouling effects.
