Patent ID: 7264870

Claim:
An adhesive tape which can be bonded to a substrate and thereafter released from the substrate without leaving a residue or damaging the substrate by pulling on the adhesive tape, said adhesive tape comprising: a) a backing comprising a foam material, said backing having a thickness of 200-600 μm, and exhibiting a modulus of elasticity of less than 16 MPa; and b) self-adhesive composition on one or both sides of said backing, said self-adhesive composition exhibiting a ratio of tear strength to stripping force (peel force) of greater than 1.2:1 at a peel angle of less than 10° from the surface of a bond formed between said adhesive tape and said substrate; whereby the backing is selected such that the backing would tear if the backing was pulled by itself without the self-adhesive composition with the same force necessary to remove said adhesive tape from said substrate, but the backing does not tear when said adhesive tape is removed from said substrate.
