Description

Technical Field

[0001] The utility model mainly relates to the technical field of PE films, and in particular to an easy-to-tear environmentally friendly PE film for packaging. Background Art

[0002] PE film is mainly used to protect the products from pollution, corrosion, scratches during production, processing, transportation, storage and use, and to protect the original smooth and shiny surface.

[0003] The inventor discovered the following defects during the operation of the specific embodiment:

[0004] When packaging the existing PE film, it is necessary to first tear the PE film from the winding device, then package the product, and finally cut it according to the size of the package. However, the PE film is relatively thin, it is not easy to find an opening, and it is also inconvenient to cut. Application No. 202121811646.X discloses an easy-to-tear environmentally friendly PE film for packaging, including: a plurality of cutting openings, a card is provided at one end of the PE film, the winding shaft is made of paper material, the PE film consists of an adhesive layer, an inner layer, a heat insulation layer and a protective layer, the protective layer is arranged on the outermost layer of the PE film, the heat insulation layer is arranged on the inner side of the protective layer, the inner layer is arranged on the inner side of the heat insulation layer, the adhesive layer is arranged on the inner side of the inner layer, and the inner layer is made of high-density polyvinyl chloride. This application sets the cutting opening at the edge of the PE film. When the PE film is stretched, it is easy to tear the PE film, causing the product to be easily torn in the middle of the wrapping packaging. In addition, the PE film has a certain elastic tension. The bevel of the card cannot move when the PE film is cut. The PE film is cut in a positioned manner, so the PE film is not easily cut and broken. Secondly, the PE film is prone to generate static electricity when packaging the product. The middle part of the PE film will also be arched due to static electricity, affecting the packaging effect of the product.

[0005] It should be noted that the above contents belong to the technical cognition scope of the inventor. Since the technical contents in this field are vast and too complicated, the above contents of this application do not necessarily constitute prior art. Utility Model Content
