[0002] A protective film is a film used to protect products. It is a colorless and transparent plastic product, generally processed from thermoplastic resins such as PE, PP, PVC, and PET. According to different materials and uses, protective films can be divided into various types, such as protective films for digital products, automotive protective films, household protective films, food preservation protective films, etc. In addition, there is also a die-cut protective film, which is a protective material processed by die-cutting technology and has characteristics such as scratch resistance, dust prevention, and fingerprint prevention. In order to endow the protective film with more functions, several functional layers are generally added to improve the performance of the protective film, which is also called a multi-functional protective film with multiple layers. However, when the multi-functional protective film with multiple layers is in use, its hardness is poor, sharp objects are likely to scratch the protective film, and its service life is low, having certain deficiencies.

[0014] To make the objectives, technical solutions, and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the specific embodiments and with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present utility model and the features in the embodiments can be combined with each other.

[0015] Some embodiments of the present utility model will be described below in conjunction with the accompanying drawings to provide a multi-functional protective film.

[0016] Embodiment 1:

[0017] Referring to Figure 1 and Figure 2 , which is the first embodiment of the present utility model, this embodiment provides a multi-functional protective film, including a base layer 100, an elastic buffer layer 200, an anti-static silicone adhesive layer 300, an anti-ultraviolet film 500, a reinforcing layer 600, and a nano-coating 700.

[0018] Specifically, the base layer 100 is a PET base film. During use, the PET base film is a film made by biaxially stretching a polyethylene terephthalate polymer, and has characteristics such as high light transmittance, low haze, and high brightness.

[0019] Specifically, the elastic buffer layer 200 is disposed at the bottom of the base layer 100. The elastic buffer layer 200 is made of polyurethane foam, and the elastic buffer layer 200 is adhesively connected to the base layer 100 through an adhesive. During use, the elastic buffer layer 200 can absorb and disperse external impact forces, reducing damage to the protective film and the protected object caused by impact.

[0020] Specifically, the anti-static silicone adhesive layer 300 is disposed at the bottom of the elastic buffer layer 200. A lower release film 400 for protection is bonded to the bottom of the anti-static silicone adhesive layer 300. During use, the anti-static silicone adhesive layer 300 serves two purposes. One is to prevent static electricity accumulation, and the other is to provide stable adhesive strength. Static electricity accumulation may cause damage to the protected product, such as breakdown of electronic components and dust adsorption. The stable adhesive strength ensures that the protective film can be firmly attached to the surface of the protected object and is not easily detached or displaced. The lower release film 400 is used to protect the anti-static silicone adhesive layer 300.

[0021] Specifically, the ultraviolet-resistant film 500 is disposed on the top of the base layer 100. During use, the ultraviolet-resistant film 500 can block ultraviolet rays and extend the service life of the protective film.

[0022] Specifically, the reinforcing layer 600 is disposed on the top of the ultraviolet-resistant film 500. The reinforcing layer 600 is a net structure woven from polyester fibers. During use, the polyester fibers can effectively improve the anti-tear and anti-puncture capabilities of the protective film, enhancing the strength, wear resistance, anti-tear property, and anti-puncture ability of the protective film.

[0023] Specifically, the nano-coating 700 is disposed on the top of the reinforcing layer 600. An upper release film 800 for protection is bonded to the top of the nano-coating 700. During use, the nano-coating 700 can enhance the hardness of the protective film and prevent it from being scratched by sharp objects. The upper release film 800 is used to protect the nano-coating 700.

[0024] The working principle and usage process of the present utility model: During use, first, the nano-coating 700 can enhance the hardness of the protective film and prevent it from being scratched by sharp objects. Then, since the reinforcing layer 600 is woven from polyester fibers, these fibers can effectively improve the anti-tear and anti-puncture capabilities of the protective film, enhancing the strength, wear resistance, anti-tear property, and anti-puncture ability of the protective film. Finally, the elastic buffer layer 200 can absorb and disperse external impact forces, reducing damage to the protective film and the protected object caused by impact, and the ultraviolet-resistant film 500 can block ultraviolet rays to extend the service life of the protective film.
