Description

Technical Field

[0001] The utility model relates to the technical field of composite matte white films, in particular to a composite matte white film. Background Art

[0002] Films are very common in our lives. For example, some furniture, home appliances, panels, mechanical parts, and other products are covered with films to protect the products. The patent document with authorization announcement number CN206277752U, entitled "A High-Stiffness Composite Matte White Film," includes a waterproof layer, an upper matte white PET layer, a mesh layer, and a lower matte white PET layer. The mesh layer has a number of through-holes, and a number of sealed cavities are formed between the upper matte white PET layer, the mesh layer, and the lower matte white PET layer. This simple structure forms sealed cavities between the upper matte white PET layer and the lower matte white PET layer by adding the mesh layer and through-holes. The sealed cavities are filled with air, so pressure is generated in the sealed cavities and acts on the composite matte white film, making it stiff and wrinkle-resistant. The waterproof layer further makes the composite matte white film waterproof, and moisture cannot enter the sealed cavities, thereby extending the service life of the composite matte white film. However, the protective effect of the high-stiffness composite matte white film is limited. Hard objects can easily pierce the composite matte white film and then scratch the protected product. Therefore, a composite matte white film is proposed to improve the protective effect of the product. Utility Model Content
