Description

Technical Field

[0001] The utility model belongs to the technical field related to release films, and in particular relates to a release film with large convex dots and grid multiple embossed patterns. Background Art

[0002] In order to increase the release force of plastic film, release film is usually treated with plasma, fluorine or silicone release agent is applied to the surface of the film material, such as PET, PE, OPP, etc., so that it can show extremely light and stable release force for various organic pressure-sensitive adhesives (such as hot melt adhesive, acrylic adhesive and rubber pressure-sensitive adhesive). According to the different required release force of release film and the different viscosity of the isolation product adhesive, the release force is adjusted accordingly to achieve extremely light and stable release force when peeling. The existing release film is in use. With the development of science and technology, release film is used more and more in society. However, in the die-cutting process for ultra-thin adhesive products, in automated operations, when the material is peeled off at the corner, the flat release film has a greater electrostatic adsorption effect, which makes it difficult to start peeling and may also cause product peeling failure. Utility Model Content

[0003] The purpose of the utility model is to provide a release film with large convex dots and multiple grid embossed patterns, so as to solve the problem in the die-cutting process for ultra-thin adhesive products proposed in the above background technology that, in automated operations, when the material is peeled off at a corner, the flat release film has a greater electrostatic adsorption effect, making it difficult to start peeling and causing product peeling failure.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a large convex point plus grid multiple embossed release film, comprising a film body and convex blocks;

[0005] The front side of the film body is provided with convex embossings at equal intervals;

[0006] The front ends of the plurality of protrusions are all pressed and provided with horizontal lines and vertical lines, and the horizontal lines and vertical lines form a well-shaped pattern on the surface of the protrusion.

[0007] Preferably, the plurality of protrusions, horizontal lines and vertical lines are formed by pressing with specially designed grid line hot-pressed steel rollers.

[0008] Preferably, the film body is composed of a base film, a silicone oil release layer and a color base layer, and a silicone oil release layer is arranged on the upper end of the base film.

[0009] Preferably, a color base layer is provided at the lower end of the base film, and the color base layer is used to increase the base color of the base film to form films of different colors.

[0010] Preferably, an anti-oxidation layer is disposed on the upper end of the silicone oil release layer, and the anti-oxidation layer is used to prevent the base film from being oxidized. A transparent protective layer is disposed on the upper end of the anti-oxidation layer, and the transparent protective layer can reduce damage to the coating below caused by impact.

[0011] Preferably, a wear-resistant layer is provided on the upper end of the transparent protective layer, and the wear-resistant layer is used to increase the friction resistance of the surface. An antistatic layer is provided on the lower end of the color base layer, and the antistatic layer is used to reduce the generation of static electricity.

[0012] Preferably, a pressure-sensitive adhesive layer is provided at the lower end of the antistatic layer, and the pressure-sensitive adhesive layer is used for bonding and fixing to the surface of an object.

[0013] Compared with the prior art, the utility model provides a large convex point plus grid multiple embossed release film, which has the following beneficial effects:

[0014] 1. Through the specially designed grid line hot-pressed steel roller, the horizontal and vertical lines form a well-shaped pattern on the surface of the bump, so that the release surface forms a special grid line and a staggered pattern of bumps. By pressing the special surface texture, the horizontal and vertical lines form a well-shaped pattern, which makes the soft peeling material easier to peel in the 90-degree angle peeling process, improving the automated operation efficiency and yield of the product. By adding bumps, horizontal and vertical lines on the film body, the structural support hardness of the film body can be increased, and the film can be better removed during the film removal process.

[0015] 2. The applicability of the release film can be increased by adding some layers in the processing and production of the base film. The anti-oxidation layer on the top of the silicone oil release layer can prevent the base film from oxidizing and increase its service life, while the wear-resistant layer and the transparent protective layer can increase the durability of the base film and prevent the base film from being damaged within a certain friction and scratching force. The anti-static layer can avoid electrostatic adhesion caused by the adsorption force of static electricity during the processing and use of the film. This can solve the problem that the existing release films are often developed for specific fields. When the demand for release films for some product packaging is small, the cost of producing suitable release films is often considered to be high, so they are chosen for application. The applied release films cannot better meet the needs of the products used, thereby making the release film too single in adapting to the products. BRIEF DESCRIPTION OF THE DRAWINGS
