Blue4est® is the first and so far only thermal paper in the world that has been approved for direct food contact. It meets consumers' desire for sustainable alternatives and at the same time allows paper receipts to be stored for very long periods of time without any loss in quality. Blue4est® is free of chemical developers and can easily be used in common POS thermal printers. The paper’s opaque functional layer turns transparent due to the effects of heat, and the black layer beneath it is revealed.
Blue4est® is a product of the Koehler Paper Group. Koehler is a specialty paper manufacturer headquartered in the Black Forest and is one of the world's leading manufacturers of thermal paper. Innovations such as Blue4est® are part of the corporate strategy, which aims to bring ever better products to the market through new and further developments.
