Abstract

Use of a transparent grip tab for a strip of adhesive film for a temporary bond based on thermoplastic rubber and tackifier resins, where the adhesive film is of high elasticity and low plasticity and where the adhesion is lower than the cohesion, the adhesion largely disappears when the film is extended, the ratio of peel force to tear load is at least 1:1.5, and where an adhesive bond produced therewith can be detached by pulling on the adhesive film in the direction of the bond plane.
