Abstract: A method for the production of environmentally compatible decorative labels, which are produced without using a PVC film, is described. The method involves the application of an embossing film, which is capable of transferring heat, on a substrate comprising a separation paper, an adhesive layer, and a plastic film made of homopolymers or copolymers of ethylene with a crystallite melting point (DIN 53765) of 110.degree. to 120.degree. C., a heat of fusion (DIN 53765) of 125 to 180 J/g, melt index (DIN 53735) of 2.0 to 3.5 g/10 min. The embossing film contains a melt adhesive layer that can be activated at 110.degree. to 230.degree. C. The embossing process takes place at a temperature of 110.degree. to 230.degree. C. under a pressure of 1.0 to 7.0 bar for a period of 3 to 0.3 sec.
