Description

Technical Field

[0001] The utility model relates to the technical field of protective films, in particular to a wire drawing film. Background Art

[0002] Drawing film is a plastic film made of polymer materials such as polyethylene and polypropylene. It is known for its high flexibility, high transparency, high tensile force and tension. The main preparation processes include melt extrusion, film blowing and injection molding, which ensure that the drawing film has excellent physical properties. In addition, with the improvement of environmental awareness and the popularization of the concept of sustainable development, more and more companies and research institutions have begun to pay attention to the environmental performance and sustainability of drawing film. They reduce energy consumption and waste emissions in the production process of drawing film by developing new environmentally friendly materials and optimizing production processes, so as to achieve green production of drawing film.

[0003] There are many types of brushed films on the market, and the inner surfaces of most brushed films are flat. When they are glued to the surface of an object, gas will accumulate in some parts during the gluing process because the inner surface is too flat and lacks a corresponding air guide structure. The gas cannot be discharged normally, causing the part to bulge, affecting the normal lamination operation and the appearance, which brings inconvenience to the user. In view of this, we propose a brushed film. Utility Model Content
