Manufacturing method of mobile phone protective film

The invention relates to a manufacturing method of a mobile phone protective film. The mobile phone protective film comprises a release film, an IR protective film, a screen protective film and two isolating films, wherein the IR protective film and the screen protective film are attached to the release surface of the release film, a first lug is attached to the top of the IR protective film, a second lug and a third lug are attached to the positions, close to the upper edge and the lower edge, of the right side of the screen protective film respectively, and the two isolation films are obliquely attached to the middle of the screen protective film in parallel in a spaced mode. By the adoption of the manufacturing method, due to the fact that the second lug and the third lug are directly attached to a screen protective film material strip in the die cutting mode, on one hand, an auxiliary material (a PE reticulate film) are saved, production cost is correspondingly reduced, productionefficiency is correspondi
