<p>The invention relates to a counterfeit-proof metallic foil (1), whose surface is structured in at least one given subsection (2, 4), said subsection having a refractive value that differs from that of the remaining surface area (3, 5). The inventive metallic foil is suitable for use as packaging material for medicaments amongst other things. The supplier or consumer can thus verify by means of the given surface structure, which functions as an identification mark, whether he or she has acquired a genuine product. If a substantial part of the surface of the metallic foil is structured, the foil appears to contain a printed image and can thus also be used as a decorative foil or as an advertising medium.</p> |
