Description

Technical Field

[0001] The present application relates to a protective film, in particular to a tear-resistant protective film. Background Art

[0002] Protective films can be divided into digital product protective films, car protective films, household protective films, food preservation protective films, etc. according to their uses. With the popularity of digital products such as mobile phones in China, protective films have gradually become a general term for screen protective films. The self-adhesive layer of self-adhesive protective films is generally EVA, ultra-low density polyethylene or polyolefin plastic resin.

[0003] When the protective film is pasted on the screen, the side film on the protective film is torn off first, and then the protective film is aligned and pasted on the screen. When tearing off the protective film, it is easy to damage the protective film by only lifting one corner and then tearing it off. In addition, since the traditional protective film does not have tensile properties, it is easy to crack when torn off, resulting in damage to the protective film. Therefore, an anti-tear protective film is proposed to address the above problems. Summary of the invention

[0004] In this embodiment, a tear-resistant protective film is provided to solve the problem of tearing of the protective film in the prior art due to the inconvenience of tearing and poor tensile properties during use.

[0005] According to one aspect of the present application, a tear-proof protective film is provided, comprising a protective film main body; a self-adhesive layer is provided on the bottom surface of the protective film main body, and a dust-proof side protective film is pasted on the bottom surface of the self-adhesive layer, an end tear film is inserted inside one end of the dust-proof side protective film, and the top surface of the end tear film is pasted on the bottom surface of the protective film main body, an upper protective tear film is fixed on the top surface of the end tear film on the side of the protective film main body, and a connecting pad is fixed on the top surface of the upper protective tear film, and the bottom surface of the connecting pad on the side of the upper protective tear film is attached to the top of the protective film main body.

[0006] Furthermore, the protective film body includes an inner polyester film protective layer, a linear low-density polyethylene anti-stretch layer, a reinforced glass tempered film layer, a special treatment layer and an outer polyester film protective layer, the bottom surface of the inner polyester film protective layer is provided with a linear low-density polyethylene anti-stretch layer, and the bottom surface of the linear low-density polyethylene anti-stretch layer is provided with a reinforced glass tempered film layer, the bottom surface of the reinforced glass tempered film layer is provided with a special treatment layer, and the bottom surface of the special treatment layer is provided with an outer polyester film protective layer.

[0007] Furthermore, the length of the dustproof side protective film is equal to the length of the protective film body, and one end of the dustproof side protective film close to the end tear film is attached to the bottom surface of the end tear film.

[0008] Furthermore, the thickness of the connecting spacer is equal to the thickness of the protective film body, and the length of the end tear film is equal to the length of the upper protective tear film.

[0009] Furthermore, the thickness of the linear low-density polyethylene anti-stretching layer is less than the thickness of the polyester film protective layer, and the thickness of the reinforced glass tempered film layer is equal to the thickness of the polyester film protective layer.

[0010] Furthermore, the thickness of the special treatment layer is equal to the thickness of the reinforced glass tempered film layer, and the thickness of the outer polyester film protective layer is equal to the thickness of the linear low-density polyethylene tensile resistance layer.

[0011] Through the above-mentioned embodiments of the present application, an auxiliary tearing structure is adopted. When tearing off the protective film, one end of the protective film body can be completely separated from the dustproof side protective film by clamping the end tearing film and the upper protective tearing film, thereby avoiding the tearing caused by tearing through the corner of the protective film body. The tensile strength of the linear low-density polyethylene tensile strength layer is used to reduce the tearing caused by the protective film being torn, thereby solving the problem of tearing caused by the inconvenience of tearing and poor tensile strength of the existing protective film during use, and greatly improving the practicality of the protective film.
