Koehler Paper’s Blue4est® thermal paper is highly valued in the Renchtal due to its recyclability

The blue thermal paper from Koehler Paper, known under the trade name Blue4est®, is becoming increasingly popular due to its sustainability; a result of a complete absence of color developers and that it can be easily disposed of as wastepaper. The blue checkout rolls from the world’s leading thermal paper manufacturer from Oberkirch have now become the subject of a promo- tional campaign in the Renchtal region.
Eight Oberkirch Businesses Campaigning for a Green Renchtal By Printing Their Logos on the Back of Blue Checkout Rolls
Eight businesses and restaurants from the city Oberkirch have come together voluntarily to use their logos on the back of the blue till paper in an act of solidarity to campaign for a green Renchtal. In addition to the eight logos, they are also highlighting the main advantage of the blue thermal paper: It is environmentally friendly and can be recycled. This makes it clear to customers that their blue receipt is helping to protect the environment and represents an even greener Renchtal. The promotional campaign is being supported by Koehler Paper, whose headquarters are located in the Renchtal region, and has been joined by the following business and restaurants: Lui e Lei, Elfen-Naht, Gaisbacher Hof, Bauzentrum Rendler, Hotel die Alm, Renchtal Tourismus, Julius Renner, and Cecil-Store. Participants received their first rolls of till paper with the impressive rear printing free of charge. Sebastian Früh, director Thermal Paper Division at Koehler Paper, says: “We are delighted that our blue thermal paper has also been so well received in the Renchtal region. I am impressed by the shared commitment and the initiative shown that has made this campaign possible. Every business and restaurant that uses our blue checkout rolls is making a statement for the environment. That’s why we were so happy to support this campaign.” Oberkirch Mayor Christoph Lipps also strongly welcomed the joint campaign: “I’m so happy that the businesses and restaurants taking part in the campaign identify so strongly with the city of Oberkirch and the beautiful Renchtal region that they decided to join this promotional campaign. On behalf of the city, I would like to thank them for this excel- lent collaboration.”
“Blue is the New Green” – Koehler’s Advertising Campaign for its Blue Thermal Paper
The Blue4est® paper from the Black Forest has no chemical developers, which not only means it is recy- clable, but also that it is approved for direct contact with food. It has been used as an eco-friendly alter- native in the retail sector for some time now, in the form of checkout rolls for example. Unlike standard white thermal paper, with Blue4est®, the text is not produced through a chemical reaction to heat but rather using a physical reaction. An opaque functional layer on the paper becomes transparent when sub- jected to heat, which results in the black layer below becoming visible. Compared to conventional thermal paper, the printed image of Blue4est® is also extremely resistant to environmental influences such as sun- light and moisture. Where printouts are stored in normal storage conditions, they remain legible for more than 35 years.
