A technical revolution for Coca-Cola delighted the expert jury of the Promotional Gift Award 2018 – and incidentally heralded a new era of brand staging at the point of sale (POS). The packaging specialist Karl Knauer KG (Biberach, Germany) and their partner Inuru GmbH were awarded a prize for the illuminated label in the category “Refinement technology”. The innovative technology was developed and patented by Inuru. The printed, flexible organic light emitting diodes (OLEDs) impressively show what is already possible thanks to OLED-printing: Brand presentations at the POS which magically attract attention and at the same time are completely sustainable and environmentally compatible.

The prototype of the illuminated label was jointly developed by Karl Knauer KG and Inuru GmbH by order of Coca-Cola. When pressing a printed “Play” symbol, the label starts to shine. The light effect is so strong that it catches one’s eyes even in bright daylight.

OLEDS are only a few nanometres thick, self-radiating, planar light sources consisting of organic semiconductors. They are fully printed with all electronic components, including batteries. The benefit: Compared to electroluminescence the OLEDs are 100-500 times brighter, however, require only a fraction of the energy and can be used cost effectively even on heavily arched surfaces.

In the packaging industry the OLED technology is regarded as a sustainable smart, green revolution, because the elements used can be recycled and easily disposed of in accordance with the legal requirements. Even composting is possible. Thanks to the thin design only a minimum material input is required, which can be recycled through recovered paper.
