Detailed ways

In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below in combination with specific embodiments and with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments of the present utility model and the features in the embodiments can be combined with each other.

It should be understood that these descriptions are exemplary only, and are not intended to limit the scope of the present invention.

Some embodiments of the present invention are described below in conjunction with the accompanying drawings to provide an easy-tear release film.

Embodiment one:

Referring to Figures 1-3, it is the first embodiment of the present utility model, which provides an easy-to-tear release film, including a release film body 1, and a foam 3 bonded to the top of the release film body 1 , the top of the foam 3 is bonded with a waterproof membrane 5, and the corners of the foam 3 and the waterproof membrane 5 are bonded with a plastic corner 11, and the top of the plastic corner 11 is provided with a tear strip 111. In specific use, the foam 3 has certain elasticity, can improve the wear-resisting effect of release film, and waterproof film 5 prevents moisture from entering, and tear strip 111 can pinch, and then can drive plastic corner 11 by tear strip 111, so that tear release film.

Further, the top of the release film body 1 is provided with a first double-sided adhesive 2, the release film body 1 is bonded and connected with the foam 3 through the first double-sided adhesive 2, and the top of the foam 3 is provided with a second double-sided tape. The glue 4 and the foam 3 are bonded and connected with the waterproof membrane 5 through the second double-sided adhesive 4. In specific use, the first double-sided adhesive 2 and the second double-sided adhesive 4 are convenient for fixing the foam 3 and the waterproof membrane 5 on the Release film body 1.

Further, the two plastic corners 11 are distributed at the two corners on the right side of the release film body 1 .

Embodiment two:

Referring to Fig. 1, it is the second embodiment of the utility model, which is different from the first embodiment in that: the top of the waterproof membrane 5 is provided with a first antistatic coating 6, a thermal insulation layer 7, and an anti-fog layer 8 in sequence And the second antistatic coating 9, in specific use, the heat insulation layer 7 can block heat, avoid the phenomenon that heat causes the connection part of the release film and the object to be glued, and the anti-fog layer 8 can prevent the surface of the release film from producing water. Mist for ease of use.

Further, the first antistatic coating 6 and the second antistatic coating 9 are ethyl silicate antistatic layers, and in specific use, the first antistatic coating 6 and the second antistatic coating 9 can avoid The accumulation of static electricity greatly reduces the difficulty of tearing off the release film.

Embodiment three:

Referring to Fig. 1, it is the third embodiment of the present utility model, and it is different from the first two embodiments in that: the top of the second antistatic coating 9 is bonded with a PET protective layer 10, and in specific use, the PET protective layer 10 It has a protective effect and prevents the release film from being scratched.

The working principle and application process of the utility model: when in use, the first double-sided adhesive 2 can firmly fix the foam 3 on the release film body 1, and after fixing, the foam 3 has elasticity, light weight, and can be pressed quickly.
