Abstract
A flexible electroluminescent film, 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, inverter, switch, integrated circuit, 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.
