Further, the thickness of the high transparency PET base layer is set to be 1.5 mm to 2 mm.

Further, the disposable liner is provided as a transparent soft plastic film, and the area thereof is set to be not smaller than the area of the adhesive layer.

Further, the anti-fingerprint coating is configured to apply a frosted particle structure.

Compared with the prior art, the beneficial effects of the present invention are:

1. By adding a highly transparent PET base layer and a scratch-resistant hard layer to the interior of the anti-glare film, the hardness of the film body is improved, thereby ensuring protection of the capacitive screen during the anti-glare process and avoiding Its damage has extended its service life.

2. By setting the anti-fingerprint coating coated with the frosted particle structure, the capacitive screen can effectively avoid the pollution of the screen surface caused by the fingertip touch during use, and is economical to use.

3. By adding a certain thickness of AG glass in the middle of the film body and protecting it, it can not only achieve the anti-glare effect of the film body, but also protect itself and facilitate the promotion.
