Problems solved by technology

[0003] The polypropylene film in the prior art has a single structure. When in use, the films tend to stick together, causing the film to be easily damaged. The polypropylene film in the prior art has poor toughness and is prone to breakage. Moreover, the film’s The antistatic ability is relatively weak, and at the same time, the molding efficiency of the polypropylene film in the prior art is slow during preparation, therefore, it is necessary to design a kind of polypropylene film and its preparation method

Abstract

The invention discloses a polypropylene film and a preparation method thereof. The polypropylene film comprises a polyurethane layer, a first polypropylene resin layer, a second polypropylene resin layer, reinforcing layers and an anti-adhesion layer, wherein both sides of the polyurethane layer are respectively adhered to the first polypropylene resin layer and the second polypropylene resin layer through an adhesive, the outer sides of the first polypropylene resin layer and the second polypropylene resin layer are paved with the reinforcing layer, the reinforcing layer comprises a lubricating layer and an antistatic layer, one side of the lubricating layer is provided with the antistatic layer, and the outer side of the reinforcing layer is provided with the anti-adhesion layer. The preparation method comprises: 1, material selection, 2, molding, 3, horizontal and vertical stretching, 4, thickness detection, and 5, corona treatment. According to the present invention, the structureof the film is simple, and the film cannot be adhered during the use, and has advantages of good toughness, static electricity resistance, convenient preparation and high molding efficiency.

Description

technical field [0001] The invention relates to the technical field of polypropylene films, in particular to a polypropylene film and a preparation method. Background technique [0002] Polypropylene film will be a plastic product made of high-molecular polypropylene, which is widely used in food packaging, medicine and chemical fields. [0003] The polypropylene film in the prior art has a single structure. When in use, the films tend to stick together, causing the film to be easily damaged. The polypropylene film in the prior art has poor toughness and is prone to breakage. Moreover, the film’s The antistatic ability is weak, and at the same time, the molding efficiency of the polypropylene film in the prior art is slow during preparation. Therefore, it is necessary to design a polypropylene film and a preparation method. Contents of the invention [0004] The object of the present invention is to provide a kind of polypropylene film and preparation method, to solve the...
