Abstract: The invention relates to an adhesive tape carrier made of a film, onto at least one side of which film an adhesive material is applied, wherein the film is a monoaxially stretched film made of polypropylene which contains at least 80 percent by weight polypropylene which has been processed in advance at least once, preferably has been extruded at least once, wherein the film has a stretching ratio during stretching in the longitudinal direction of 1:4 to 1:10.

Abstract: A double-sided adhesive tape having a heat-activatable adhesive layer protected with an interliner, in order to allow such tapes to be guided stably over cutting and winding units and also to be stably stored and transported, has a composite system comprising: an adhesive tape (A) comprising: a pressure sensitive adhesive layer, and a heat-activatable adhesive layer; a release liner situated on the pressure sensitive adhesive layer of the tape (A); and an adhesive tape (B) comprising: a carrier layer, a release layer on one side of the carrier layer, and a pressure sensitive adhesive layer on the side of the carrier layer opposite the release layer and in direct contact with the heat-activatable adhesive layer of tape (A). Also disclosed is a method for producing a composite system of this kind, and the specific use of the tape (B).
