Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of PE films, and more specifically to a composite PE film. Background Art
[0002] PE protective film is the simplest macromolecular organic compound and the most widely used macromolecular material in the world today. The biggest advantage of PE protective film is that the protected products are not polluted, corroded or scratched during production, processing, transportation, storage and use, and the original smooth and shiny surface is protected, thereby improving the quality and market competitiveness of the products.
[0003] When the existing PE protective film is used, it will be scratched and torn when subjected to a large external force, and thus cannot provide stable protection for the items protected inside, thereby reducing the actual use effect of the PE protective film. To this end, we propose a composite PE film. Utility Model Content
