Abstract: A method of separating two substrates bonded with a redetachable, at least single-sidedly pressure-sensitive adhesive strip composed at least of a) a core layer which has a breaking extension of at least 300%, b) an outer carrier layer which has a breaking extension of not more than 120% and which at least sectionally is connected to the core layer such that it separates from the core layer when the latter is extensionally stretched, and c) a first adhesive layer which is applied at least sectionally to the side of the outer carrier layer that is opposite the side connected to the core layer, in which the core layer is stretched in the direction of the bond plane, starting from a region which has been made nonadhesive, until the core layer releases from at least one of the outer carrier layers so that the two substrates are separated from one another.

Abstract: A auxiliary adhesive tape is used as a removal aid for removing an elastic, double-sided adhesive film which can be removed, without leaving any residue or causing any destruction, by means of stretching and elongation in the bond plane, wherein said adhesive film has at least one end which is designed as a catch, wherein an object is attached by means of the same, and the same works by means of being pulled at a removal angle of >45° around an edge of the attached object. The auxiliary adhesive tape in this case is adhered around this edge and is a single-sided adhesive tape having a carrier, wherein the carrier satisfies at least one of the two properties below: a) the carrier consists of a low-energy polymer, b) the carrier has a structured surface.
