Abstract

The invention relates to a flat structure that is at least partially provided with a self-adhesive substance, the latter being present on a first surface layer of the flat structure in the form of a plurality of geometric bodies. According to the invention, the surface of at least some of the geometric bodies is at least partially treated in such a way that the treated part of the surface has a lower degree of adhesion than the non-treated self-adhesive substance.
