    Abstract: The invention relates to an adhesive film strip comprising at least two, particularly three, layers, which adhesive film strip can be detached without residues and nondestructively by expansive stretching substantially in the adhesion plane, with a carrier on which a first external adhesive compound layer is present on at least one side, wherein the adhesive compound layer consists of adhesive compound formed on the basis of vinyl aromatic block copolymers and adhesive resins, wherein at least 75% of the resin (relative to the overall resin content) is selected with a DACP (diacetone alcohol cloud point) of greater than −20° C., preferably greater than 0° C., and the carrier has at least one layer made from a polyurethane with an elongation at break of at least 100% and a restoring power of more than 50%. A nonpolar hydrocarbon resin or a polyterpene resin is particularly used as the tackifier for the adhesive compound(s).
