Description

Technical Field

[0001] The utility model relates to the technical field of mobile phone screen protective film production, in particular to a cutting device for mobile phone screen protective film production. Background Art

[0002] Screen protector, also known as mobile phone beauty film or mobile phone protective film, is a cold-mounted film used to mount mobile phone screens. Currently, the best screen protector on the market is AR material. AR is a synthetic material, generally divided into three layers, with silicone as the adsorption layer, PET as the middle layer, and the outer layer as the special treatment layer. The special treatment layer is generally divided into two types, AG treatment layer and HC treatment layer. AG is anti-glare treatment, and frosted protective film adopts this treatment method. HC is hardness treatment, which is the treatment method used for high-transmittance protective film. The characteristics of this screen protector are that the screen is non-reflective and has high light transmittance (more than 95%), which will not affect the display effect of the screen. Moreover, the surface of the material has been processed by a special process, and its texture is relatively soft, with strong anti-friction and anti-scratch capabilities. There will be no scratches even after long-term use. The chemical material silicone is used to adhere to the mobile phone screen, so it will not cause damage to the screen itself, and will not leave marks after tearing it off. It can also be reused after cleaning. It can also be easily bought on the market, and the price is more expensive than PET material.
