Easily-torn high-stiffness adhesive tape

The utility model discloses an easy-to-tear high-stiffness adhesive tape which comprises a supporting structure, the supporting structure comprises an upper supporting layer, a middle supporting layer and a lower supporting layer, an upper adhesive layer is arranged on the upper surface of the middle supporting layer, a lower adhesive layer is arranged on the lower surface of the middle supporting layer, and a release layer is arranged between the upper supporting layer and the upper adhesive layer. During use, the lower supporting layer and the middle supporting layer can be regarded as an integral composite base material, and due to the fact that the requirement for tensile strength of the base material of the supporting layer of the winding adhesive tape is high during production and winding, winding connection failure can be caused by too high or too low tensile strength, and therefore the lower supporting layer and the middle supporting layer can improve the tensile strength of the adhesive tape and mean
