Abstract: The invention relates to a contact-adhesive tape which can be removed damage-free and residue-free by stretching the tape substantially within the adhesion plane and which consists of one or more adhesive substance layers, all made of a contact-adhesive substance expanded with micro-balloons, and one or two optional intermediate backings. The disclosed contact-adhesive tape consists exclusively of the aforementioned adhesive substance layers and optional intermediate backings, and the one external upper surface as well as the one external lower surface of the contact-adhesive tape are formed by said adhesive substance layer or layers.
