Abstract

The invention relates to an adhesive strip which can be detached substantially on the adhesion plane in a residue-free and nondestructive manner by stretching, said strip consisting of one or more adhesive material layers and optionally one or more intermediate carrier layers, at least one of the adhesive materials layers containing at least one filler, the primary particles of which can be individually separated, wherein the primary particles (i) are substantially spherical and (ii) have an average diameter d(0.5) of less than 10 μm, and the ratio of the average diameter d(0.5) of the primary particles to the thickness of the adhesive material layer in which the primary particles are contained is less than 1:2. The invention also relates to the production and use of said adhesive strip.
