Embodiment Construction

[0022] The present invention will be further described below in conjunction with accompanying drawing.

[0023] The invention provides a hardened matte hot-melt composite film, the structure of which is figure 1 As shown, the composite film has a five-layer structure, which is a hardened matte UV coating 1, a substrate layer 2, an adhesion-promoting layer 3, an adhesion-promoting layer 4, and a hot-melt resin layer 5 from top to bottom. The base layer 2 is composed of hot melt resin particles through melt extrusion and the base layer composite hot melt resin layer 5, the base layer 2 is coated with a hardened matte UV coating 1, between the base layer 2 and the base layer An adhesion-promoting layer 3 and an adhesion-promoting layer 4 are added between the hot-melt resin layers 5 .

[0024] The base material layer is made of one of polyethylene terephthalate, polypropylene, polyvinyl chloride and polycarbonate film, with a thickness of 10-200um.

[0025] The hot-melt resin i...

Abstract

The invention provides a hardened matt hot-molten composite film and a preparation method thereof. The composite film is formed by melt-extruding hot-melt resin particles and compositing with a base material layer, and a matt coating coats a base material, so that hardness of the surface of the composite film is improved, light transmittance of the composite film is lowered, and anti-scratching, wear-resistant and beautiful effects are realized. A bonding assistant layer and a tackifying layer are added between the base material and a hot melt layer, so that bonding strength among layers of the composite film is improved.

Description

technical field [0001] The invention relates to the technical field of composite films, in particular to a hardened matte hot-melt composite film. Background technique [0002] With the development of polymer science and technology and the demand for lightweight products in production and life, various thin film products have been widely used in various fields of social production and life. The hot-melt composite film is made of transparent substrate coated with hot-melt resin. It is a colorless, transparent and glossy film with good mechanical properties, optical properties, electrical properties, thermal properties and chemical resistance. . Hot-melt composite films are widely used in hot-melt packaging. Plastic film is one of the representatives, and plastic film is widely used in the protection of documents, documents, photos and other paper documents. [0003] However, the plastic film is easily scratched by hard objects and sharp objects during use, which affects th...
