Contact adhesive layer produced form a melt adhesive containing, as the adhesive composition, 10 to 60 wt % of at least one copolymer based on ethylene and at least one C3 to C20 olefin obtained through metallocene-catalyzed polymerization and having an MFI value of 1 to 100 g/10 min, 20 to 70 wt % of at least one tackifying resin, 0 to 35 wt % of a plasticizer, and 0.01 to 20 wt % of additives and supplemental materials selected from stabilizers, adhesion promoters, fillers, or pigments and/or other polymers, with a layer thickness of 2 to 150 g/m2.
