[0002] Protective film is a single-layer or double-layer transparent material, usually less than one millimeter thick, with properties such as light transmittance, heat insulation and anti-stickiness. It is mainly used to protect products, isolate them from damage by oxygen, light and odor, and prevent them from being scratched. There are many types of protective films with different functions to meet the protection needs of different fields.

[0003] Existing protective films do not have a portable storage and carrying structure during use, such as a door and window protective film disclosed in application number CN02286270.6. Existing protective films of this type are not convenient to store and carry during use. Protective films without a portable outer shell often require additional storage tools such as plastic bags and folders to be found or prepared when carried, which increases the complexity and inconvenience of carrying and storing. At the same time, the protective film is easily contaminated by the external environment during carrying and storage, such as dust and dirt, and is also more susceptible to physical damage, which will greatly affect the user experience, reduce the efficiency of use and increase the complexity of use.

[0004] Therefore, it is necessary to invent a protective film that is easy to store and carry to solve the above problems. Utility Model Content
