Description

Composite film with multilayer structure

Technical Field

The utility model relates to the technical field of plastic films, in particular to a composite film with a multilayer structure.

Background

The film bag is a frequently used article in daily life, and people are used for holding various articles, so that the life of people is facilitated. For example, when shopping in supermarkets, plastic bags are needed, but with the increasing emphasis on environmental protection, the problem that the plastic bags are easy to pollute is also more and more prominent. Therefore, people want to replace the plastic bag with the paper bag and the cloth bag to reduce pollution and can use the plastic bag repeatedly, but the paper bag and the cloth bag have the problem of no water resistance and have certain limitation in use.

Disclosure of Invention

Aiming at the problems pointed out in the background art, the utility model provides a composite film with a multi-layer structure, and a bag made of the composite film has the texture of paper and cloth, can be waterproof and can be reused.

The technical scheme of the utility model is realized as follows:

the composite film with the multilayer structure comprises a heat-shrinkable film layer, wherein paper layers and cloth layers are respectively arranged on two sides of the heat-shrinkable film layer, wear-resistant film layers are respectively arranged on surfaces of the paper layers and the cloth layers, and adjacent layers are bonded through thermal viscosity-reducing pressure-sensitive adhesives.

The utility model further provides that the heat-shrinkable film layer is a PVC heat-shrinkable film.

The thickness of the heat-shrinkable film layer is 0.1mm-0.3mm.

The utility model further provides that the wear-resistant film layer is a nylon film.

The utility model further provides that the thickness of the wear-resistant film layer is 0.1mm-0.3mm.

The utility model further provides that the thickness of the paper layer is 0.1mm-0.3mm.

The utility model is further arranged that the thickness of the cloth layer is 0.3mm-0.4mm.

By adopting the technical scheme, the utility model has the beneficial effects that:

(1) The paper layer and the cloth layer are arranged between the two layers of films, so that one side of the film can present the texture of paper, the other side of the film can present the texture of cloth, the bag made of the composite film can have the texture of paper and cloth, the paper surface or the cloth surface can be selected as the outer side surface of the bag, meanwhile, the film layer can play a role in water resistance, compared with a common plastic bag, the bag made of the composite film has the texture of paper and cloth, can be favored by people and can be reused, and the whole structure of the film is high in strength, not easy to damage and convenient to reuse.

(2) Through thermal viscosity-reducing pressure-sensitive adhesive bonding between each layer of film, can expand after the glue film is heated, reduce the viscidity of gluing, moreover, when the pyrocondensation rete is heated, can shrink and curl for cloth layer and ply can be easier separation, like this after the film abandonment, can separate each layer, convenient waste garbage classification handles.
