Description

Technical Field

[0001] The utility model relates to the technical field of protective films, in particular to a protective film that is convenient for quantitative use. Background Art

[0002] Protective film is a membrane material that has a protective function on the surface of other materials. It is mainly made of polyolefin. The main function of the protective film is to protect the product from pollution, corrosion, and scratches during the production, processing, transportation, storage and use, so as to maintain the original smooth and shiny surface of the product, thereby improving product quality and market competitiveness.

[0003] Existing protective films are usually stored in rolls or sheets, but there is no special storage device, which causes the protective films to be easily scattered during carrying and may even be damaged. In addition, they cannot be taken out in a quantitative manner as needed, making them inconvenient to take out.

[0004] For example, the model protective film disclosed in the patent publication number CN216486948U is not equipped with a cutter. When it is taken out and cut, it usually requires the use of external tools such as scissors or blades. This not only increases the difficulty of cutting, but may also damage the protective film due to improper operation, affecting the use effect.

[0005] Therefore, it is necessary to invent a protective film that is convenient for quantitative use to solve the above problems. Utility Model Content
