  • Patent number: 5491012
    Abstract: Use of a strip of an adhesive film for a re-releasable adhesive bond based on thermoplastic elastomer and tackifying resins, the adhesive film having high elasticity and low plasticity and the adhesion being lower than the cohesion, the adhesive strength largely disappearing during extension of the film, the ratio of peel strength to tear strength being at least 1:1.5, and an adhesive bond produced therewith being releasable by pulling on the adhesive film in the direction of the plane of adhesion, one end of the strip being provided on both sides with a UV-opaque covering which at the same time serves as a tab for pulling.
