摘要

Packaging or packaging auxiliary aid comprises a substrate (10) having a surface (11) which reflects visible light. A layer sequence consisting of one or more ceramic layers (12, 16) made of a compound of the formula SiOx (where x = 1.5-2.0) and having a thickness of 50-2000 nm. A reflecting layer (17) made from a metal and having a thickness of 0.2-60 nm is arranged on the surface of the ceramic layers. Preferred Features: The metal layer is made from Al, Cr, Ni, Au or Ag or their alloys. The substrate is made from a film-like material.
