Blue4est®: A blue thermal paper that is one-of-a-kind, patented, and award-winning. And also durable, sustainable, and non-hazardous. This is a lot of superlatives for such a small roll of paper. But the new Blue4est® has it all – or actually not.
Blue4est® does not use Color formers and color developers – chemicals that are traditionally required to produce thermal paper. Blue4est®, on the other hand, works completely without the use of these substances. The color reaction, or alternatively thermal printing, is a purely physical reaction of the paper to heat. So that is the technology behind it.
But what does this actually mean? For example, Blue4est® is the only thermal paper worldwide that is approved for direct contact with food. No other thermal paper is more environmentally friendly and sustainable.
Well, that actually makes it an ingenious advertising medium, this blue thermal paper. The receipt as the company’s business card, sustainability in action. Every customer can experience this directly by holding a receipt in his hand, which is noticeably different simply because of the color. And not only different, but sustainable.
Thermal paper is indispensable in many areas of daily life: from sales receipts to package labels, through to logistics centers.
Continuing its role as a pioneer in this area, Koehler has now developed the next generation of thermal paper: The highly environmentally friendly and innovative Blue4est® paper.
Koehler uses the latest machinery to produce its thermal paper and distributes its thermal jumbo rolls to converters and laminators all around the world. Only then is the paper used to produce cash register rolls or self-adhesive labels.
