Abstract

The invention relates to the technical field of plastic films, and provides a rubber-mat-free pressed film which is sequentially composed of a layer A, a layer B and a layer C. The layer A is composed of a component A: 70-80 parts of a thermoplastic elastomer, 20-30 parts of polyethylene, 3-6 parts of low-density polyethylene, 1-3 parts of fluorinated polyethylene and 0.5-1 part of a film opening agent; the layer B is prepared from a component B: 70 to 80 parts of polypropylene and 20 to 30 parts of polyolefin elastomer; and the layer C consists of a component C: 70-80 parts of a thermoplastic elastomer, 20-30 parts of polyethylene, 3-6 parts of low-density polyethylene, 1-3 parts of fluorinated polyethylene and 0.5-1 part of a film opening agent. By means of the technical scheme, the problem that in the prior art, a thin film and pure cotton cloth deform during hot press forming is solved.

Description

technical field [0001] The invention relates to the technical field of plastic films, in particular to a pressure film without an adhesive pad and its preparation method and application. Background technique [0002] With the rapid development of the economy and the improvement of residents' living standards, consumers have higher and higher requirements for the comfort, feel and style of clothing. [0003] For shirts, the cuffs and collar are usually made of double-layer fabrics, and the two layers are usually bonded and fixed by a layer of film. Currently, polyethylene and polypropylene films are commonly used on the market. When preparing cuffs or collars, high temperature Thermoforming. For clothes made of pure cotton, the pure cotton fabric may be deformed by heat due to the high pressing temperature during hot pressing, but if the pressing temperature is lowered, there will be poor adhesion between the film and the fabric, and it will be difficult to wear for a long t...
