Detailed Description

In order that the manner in which the above recited features of the present utility model can be better understood, a more particular description of the utility model will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings. The following description of at least one exemplary embodiment is merely exemplary in nature and is in no way intended to limit the utility model, its application, or uses. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The back adhesive structure convenient for release film stripping as shown in fig. 1-3 comprises an adhesive layer 2, a first release layer 1 covered on the upper side of the adhesive layer 2, a second release layer 3 covered on the lower side of the adhesive layer 2, a handle 11 arranged on the side surface of the first release layer 1, a convex ridge 12 arranged on the lower side of the first release layer 1, and a convex ridge 12 parallel to the handle 11.

As shown in fig. 1 and 2, the second release layer 3 is a strip-shaped release film coiled material, and a plurality of glue layers 2 are attached to the second release layer 3 in an array. The adhesive layer 2 is foam double-sided adhesive with a rounded rectangle shape, so that the back adhesive has the characteristics of strong adhesive force, good holding power, good waterproof performance, strong temperature resistance and strong ultraviolet resistance.

As shown in fig. 1-3, the first release layer 1 is a release paper or a release film with rounded corners and rectangle equal to the glue layer 2, the first release layer 1 is attached to the upper side of the glue layer 2, and the first release layer 1 completely covers the glue layer 2. A corner of the first release layer 1 is provided with a handle 11, the length direction of the handle 11 being parallel to the angular bisector of the corner. By arranging the handle 11 in the peeling direction, the junction of the handle 1 and the first release layer 1 at the time of film tearing can be prevented from being broken. Preferably, two ends of the joint of the handle 11 and the first release layer 1 are respectively provided with a circular transition hole 111, so that local stress during peeling is reduced, and the handle 11 is prevented from being broken.
