Abstract

The invention provides an adhesive tape and a manufacturing method thereof. The adhesive tape comprises a base material layer, a stripping layer and an adhesive layer positioned between the base material layer and the stripping layer, wherein a concave-convex structure is arranged on one side, far away from the adhesive layer, of the stripping layer and / or the base material layer. The side, far away from the adhesive layer, of the stripping layer and / or the base material layer is of the concave-convex structure, so that the surface roughness of the adhesive tape is increased to reduce the contact area, the possibility of vacuum adsorption between adhesive tape die cutting sheets or adhesive tapes is reduced, the problem of sheet adhesion caused by vacuum adsorption is avoided, and the service life of the adhesive tape is prolonged. The die cutting efficiency and the yield are improved, and the machining cost is reduced.

Description

technical field [0001] The present application relates to the technical field of adhesive tapes, in particular to an adhesive tape and a manufacturing method thereof. Background technique [0002] Due to the relatively smooth and flat surface of the traditional tapes currently on the market, when the traditional tapes are die-cut into sheets and stacked in the abrasive tool during the die-cutting process, there will be vacuum adsorption between the sheets, resulting in The sheets are stuck together, which makes the manipulator unable to grab the sheets, which leads to the inability to perform subsequent operations, which reduces the die-cutting efficiency and yield, and increases the processing cost. Contents of the invention [0003] In view of this, the present application provides an adhesive tape and its manufacturing method to solve the technical problem of sheet adhesion caused by vacuum adsorption in the prior art, so as to improve die-cutting efficiency and yield, ...
