Abstract
A counterfeit-proof metal foil is textured in at least a given partial area of its surface, this partial area having a radiation refraction value which is different compared to the remaining surface area. The metal foil is suitable as a packaging material, among others for medications. The manufacturer or the consumer can check based on the given surface structure which is intended as an identification sign whether he has acquired an uncounterfeited product. If texturing takes place on most of the surface of the metal foil, this is identical to the appearance of a printed picture so that the metal foil as claimed in the invention is likewise used as a decorative foil or an advertizing medium.
