Abstract: An adhesive tape is described, which is destroyed by delamination upon removal from a substrate but which may be unwound from a supply roll without destruction. The adhesive tape comprises an inner layer of a polyolefin having 2 to 6 carbon atoms containing in a finely distributed form solid organic particles with a size of from about 0.2 to 20 microns and polyolefin cover layers on both sides of the inner layer, one of which is coated with an adhesive and the other with a release coat.

Abstract: Disclosed is an adhesive tape comprising a support film of a synthetic thermoplastic polymer, preferably polyvinylchloride or polypropylene, and an adhesive layer on one side of it, wherein the support film has a thickness less than about 35 .mu.m and preferably is stretch-oriented. Provided on the surface of the support film facing away from the adhesive layer are elevations having a depth within a range of from about 5 to 20 .mu.m.

Abstract: A pressure-sensitive adhesive tape is described, which comprises a support film formed of a co-extruded, biaxially oriented multilayer polypropylene film and an adhesive coating applied to one surface of the film. The support film is composed of at least first and second layers having different compositions. The second layer of the support film, which faces away from the adhesive coating, has a thickness of less than one third of the total thickness of the adhesive tape, and contains an anti-adhesive substance.
