ELECTROLUMINESCENT FLEXIBLE FILM FOR PRODUCT PACKAGING

摘要

A flexible electroluminescent film 10, and packaging material and packages made therefrom, that incorporates electroluminescent material within the polymer packaging film layers to enable the film to be illuminated without an external light source. The film may also comprise various thin-film items, such as power source 12, inverter 13, switch 14, integrated circuit 91, radio receiver, and speaker, all within the film layers. The film can be used in existing form and fill packaging machines without substantial modifications to the machines.
