Claim Text:
1. A pressure sensitive tape comprising: a laminated material having an axial length and a longitudinal width; the laminated material having a substrate material layer having a first surface and a second surface, a first adhesive layer, a heat activated shrink film layer having a first surface and a second surface, and a second adhesive layer, wherein the first adhesive layer is disposed between the second surface of the substrate material layer and the first surface of the shrink film layer, and the second adhesive layer is disposed on the first surface of the substrate material layer or the second surface of the shrink film layer, and wherein the second adhesive layer comprises a pressure sensitive adhesive; and the axial length of the laminated material has a curvature about the longitudinal width of the laminated material induced by heat activation of the shrink film layer, wherein the curvature is in the shape of an arc; and wherein the laminated material when extended is self-supporting, wherein the substrate material is selected from the group consisting of paper, polycarbonate, polyester, foil, cellophane, cellulose acetate, cellulose nanofibrils, and cloth; wherein the shrink film is selected from the group consisting of polyolefin and polyvinyl chloride; and, wherein the substrate material and the activated shrink film cooperate to impart the curvature which imparts stiffness to the laminated material.
