Embossed release paper

Abstract

The invention discloses an embossed release paper. The embossed release paper comprises base paper and a film-coated layer coating the surface of the base paper. The surface, opposite to the base paper, of the film-coated layer has an embossing pattern zone, and the surface of the embossing pattern zone is coated by an organosilicon release agent layer. The film-coated layer comprises the following components by weight: 100 parts of high-density polyethylene, 120 to 180 parts of low-density polyethylene, 10 to 30 parts of styrene-isoprene-styrene block copolymer, 5 to 15 parts of styrene-butadiene block copolymer, 0.5 to 1.5 parts of paraffin, 0.1 to 0.5 part of glycerol, 5 to 10 parts of POE polyolefin elastomer and 0.3 to 0.8 part of a coupling agent, wherein the POE polyolefin elastomer is polymer of ethylene and butylene or polymer of ethylene and octylene. A reticular pattern formed in the invention has clear and equally-deep amboss and uniform distribution lines; and no bubble occurs between the formed embossed film-coated release paper and a pressure-sensitive adhesive during bonding of the embossed film-coated release paper with the pressure-sensitive adhesive, so usage effect is not affected.

Description

technical field [0001] The invention relates to an 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 used by high-end products us...

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
