TECHNICAL FIELD

[0001] The utility model relates to PE film processing technical field, specifically is cutting device for PE film processing. BACKGROUND

[0002] PE film, namely polyethylene film, is a film-shaped material processed from polyethylene, a high molecular polymer.

[0003] PE film has moisture resistance and low moisture permeability, and is one of the most widely used high molecular materials in the world today. It can be divided into high-density polyethylene protective film, medium-density polyethylene and low-density polyethylene according to different densities. PE films with different densities have different properties, for example: low-density polyethylene film has good transparency and heat sealing property, can prevent water and moisture, but has low tensile strength and large tensile elongation, and is prone to wrinkling. High-density polyethylene film has better heat resistance and mechanical strength than low-density polyethylene film, has small tensile elongation, but has poor transparency. PE film is widely used in packaging, printing, wire and cable, electronics and other industries. For example, in the packaging industry, PE film is often used as food bags, clothing bags, etc.; in the printing industry, it can be used to protect the surface of PVC, PC board, aluminum plate, film and other printed nameplates; in the wire and cable industry, it can be used to protect the shaft-mounted copper wire, semi-finished product, finished product, etc.

[0004] In addition, with the development of technology, various new devices and patents for PE film are emerging. For example, some companies have developed an automatic tension control adjusting device for PE film, which can limit the PE film; some companies have developed a forming device for PE film embossing, which can adjust the pressure during PE film embossing. In general, as an important packaging material, PE film plays an irreplaceable role in modern society.
