BACKGROUND OF THE INVENTION
In general, packaging serves product protection and promotion. Attractive packaging is a soul of a product that tells the complete story about the product. The producers do not just want a product wrapped with or contained in a package system, they want some attractive means in packaging systems which not only appeal the customers but can also serve as interactive mode between producers and the consumers.
Electroluminescent (hereinafter EL) technology due to its eye catching potential is the target of packaging innovators to utilize all its properties into packaging domain. EL technology is based upon the use of conducting, insulating and luminescent inks, which are suitable for manufacturing printed EL films. In further development of this technology, the approaches have been applied in miniaturization of the electronic components, encompassing the integration of the driver into the printed EL film. Organic and printed electronics could help manufacturers to upgrade packaging plastics to active early warning systems or cardboard boxes to multi-media information carriers. Current trends and the latest developments in this area can be seen today in this domain.
Various approaches have been used as of now incorporating EL system into packaging domain. For example, one of the applications of this technology was demonstrated by DuPont during the Luxe Pack 2006, where they showed a prototype compact case, made of Surlyn by the UK Company Toly Products Ltd, in cooperation with Seribase in France. In the compact case, which was meant as a perfume packaging, a thin EL strip had been integrated to illuminate the brand name.
