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 low residual rate embossed release paper, comprising polyester film layer and film coating layer covering on the surface of the polyester film. The surface on the side of the film coating layer against the polyester film layer has a embossing pattern area and an organosilicone release agent layer is coated on the surface of the embossing pattern area. The film coating layer comprises, by weight, 100 parts of high density polyethylene, 125 low density polyethylene, 22 parts of styrene-isoprene- styrene block copolymer SIS, 8 parts of block copolymer of styrene and butadiene SBS. The coupling agent is silane coupling agent. The mesh texture embossing formed by the invention is clear, with uniform depth and distribution lines. Further, the invention also improves the anti-static performance of the film.

Description

technical field [0001] The invention relates to a low residual adhesion rate embossed release paper, which belongs to the technical field of release materials. Background technique [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 the ordinary release film is attached to the pressure-sensitive adhesive tape, air bubbles are likely to form between the two. Using embossed release paper, although it can achieve the effect of air bubbles, but because the release paper is easy to absorb water, the tear resistance is not high, it is difficult to observe the glue surface, and there are paper scraps on the edge after die-cutting, so it cannot be use...
