Problems solved by technology

[0002] Usually the release film refers to the coating of silicone oil on the surface of the polyester film to play the role of anti-sticking; the surface of the release film can have a smooth surface and a matte surface, but the pressure-sensitive adhesive tape made of this traditional release film When using label tape, the beautification effect of the glue surface is not ideal. When ordinary release film and pressure-sensitive adhesive tape are bonded, air bubbles are likely to form between the two
Using embossed release paper, although it can achieve the effect of air bubble removal, but because the release paper is easy to absorb water, the tear resistance is not high, it is difficult to observe the rubber surface, and there are paper scraps on the edge after die-cutting, so it cannot be used by high-end product used

Abstract

The invention discloses a matte antistatic embossing release film. The matte antistatic embossing release film comprises a polyester film layer and a film spraying coating layer coating the surface of the polyester film layer, wherein an embossing pattern area is arranged on the surface, opposite to the polyester film layer, of the film spraying coating layer; the surface of the embossing pattern area is coated with an organosilicone release agent layer; the film spraying coating layer is prepared from the following components in parts by weight: high density polyethylene, low density polyethylene, styrene-isoprene-styrene (SIS) block copolymer, and a block copolymer of styrene and butadiene (SBS); a POE polyolefin elastomer is a high polymer of ethylene and butene or a high polymer of ethylene and octylene; the POE polyolefin elastomer is the high polymer of the ethylene and the octylene. Reticular patterns formed by the matte antistatic embossing release film disclosed by the invention are distinct in embossing, unified in depth and uniform in distribution lines; when formed embossing film spraying release paper is attached to pressure-sensitive adhesive, no bubbles are generated between the embossing film spraying release paper and the pressure-sensitive adhesive.
