Wear-resistant matt touch adhesive film and preparation method thereof

Abstract

The invention discloses a wear-resistant matt touch adhesive film. The film is composed of a wear-resistant touch oil layer, a BOPP matt base film layer and an aqueous pressure-sensitive adhesive layer from top to bottom, and the wetting index of the upper surface of the wear-resistant touch oil layer is less than or equal to 36 dynes. The film utilizes the characteristic of being capable of direct winding and unwinding of the wear-resistant touch oil layer with the wetting index less than or equal to 36 dyne and a water-based pressure-sensitive adhesive layer, does not need to use a release paper or a release film, and has the advantages of a good touch effect, moderate initial adhesion and lasting adhesion, no adhesive residue and environmental protection. The invention also discloses the preparation method of the wear-resistant matt touch adhesive film, the method has strong controllability in operation, and is favorable for large-scale industrial production, and the prepared wear-resistant matt touch adhesive film can directly carry out label coating.

Description

technical field [0001] The invention relates to the field of adhesive films, in particular to a tactile adhesive film. Background technique [0002] Tactile film is a new variety of glazing film in China, which has the function of increasing the texture of the label surface and carton surface. The tactile film has a suede feel when touched by hand, and is a surface composite material for high-end packaging boxes or labels. In recent years, film materials with tactile effects have been researched at home and abroad, but there are obstacles in application, mainly because they are inconvenient to use. The existing tactile oil coating has a strong binding force with the adhesive, so it cannot be rolled directly. It needs to be lined with a layer of release paper or film before winding, and the release material is removed during use. Most users in the industry think it is troublesome and wasteful (high cost) to remove the release paper or release film, so they directly purchase...

In recent years, film materials with tactile effects have been researched at home and abroad, but there are obstacles in application, mainly because it is inconvenient to use

The existing tactile oil coating has a strong binding force with the adhesive, so it cannot be rolled directly. It needs to be lined with a layer of release paper or film before winding, and the release material should be removed during use.

Most users in the industry think it is troublesome and wasteful (high cost) to remove the release paper or release film, so they directly purchase the tactile film without adhesive for temporary coating on site, and this method often has low efficiency and flexibility. Disadvantages such as low performance, high energy consumption, and environmental pollution caused by the use of solvent adhesives
