[0024] It should be noted that the substrate film layer 3 is made of PET, PE or PTFE, etc. The first reinforcement layer 1 and the second reinforcement layer 2 can improve the overall strength of the release film. At the same time, the dredging exhaust member 4 can achieve a better exhaust effect to avoid the influence of the first reinforcement layer 1 and the second reinforcement layer 2 on the exhaust. Therefore, the release film has a higher strength and better exhaust performance. The exhaust column 41 can realize the flow of air and also have a certain blocking effect on fine particles. Then, the flowing air is released through the exhaust ball 42 to achieve better exhaust treatment. The antibacterial effect of the release film can be guaranteed by the first antibacterial layer 6 and the second antibacterial layer 8.

[0027] It should be noted that the first reinforcing layer 1 made of an epoxy resin film can ensure good strength, and the second reinforcing layer 2 made of a polypropylene film. Therefore, when using the first reinforcing layer 1 and the second reinforcing layer 2, the overall strength of the release film can be improved, and thus the tear resistance of the release film is improved.
[0028] In an alternative embodiment: The venting and exhausting member 4 is made of silicon carbide material, and the exhaust column 41 penetrates through the first reinforcing layer 1, the second reinforcing layer 2, and the base film layer 3.
[0029] It should be noted that the venting and exhausting member 4 made of silicon carbide material has good exhaust performance, and the exhaust column 41 is used to facilitate the exhaust treatment on both sides of the first reinforcing layer 1, the second reinforcing layer 2, and the base film layer 3.
[0030] In an alternative embodiment: Concavo-convex portions 51 are provided at one end of the first release film layer 5 and the second release film layer 7, and the first antibacterial layer 6 and the second antibacterial layer 8 are correspondingly and fittingly attached to the surfaces of the concavo-convex portions 51.
