Abstract

The invention concerns a multi-layer flexible film body (6), in particular a label film or packaging film as well as a goods identification system and uses of such a film body. The film body (6) has a carrier layer and a decorative layer system (11) which provides optically recognisable information. A plurality of layers of the decorative layer system form an electronically controlled display element (65), by the activation of which the optically recognisable information becomes visible.
