VPF introduces chemical-free thermal paper

The trend towards more durable self-adhesive materials continues and now also extends to direct thermal printing. VPF GmbH & Co. KG now uses a bluish thermal paper, called “Blue Clean”, on which printing does not result from a chemical reaction but from a physical process. The new type of paper is chemical-free and suitable as an adhesive material for direct food contact.

Consumers are familiar with blue thermal paper from retailers, where it has been used for some time. In supermarkets, for example, blue eco-receipts are increasingly replacing the old white receipts. This is not a marketing strategy, but rather an effort to use more sustainable paper in all areas. At the same time, the self-adhesive material specialists at VPF have also expanded their product range and added the new product 1470579 clean blue thermal paper 70 g/m2 to their portfolio.

The new VPF material can be used on common direct thermal printers and, compared to previous thermal papers, is free of chemical developers. It has a four-layer structure and consists of plain paper, a black pigment layer, an opaque functional layer that creates the blue coloring of the paper, and a protective layer against mechanical damage. The printed image is created physically: the opaque layer becomes transparent when exposed to heat and makes the underlying black layer visible.

According to VPF, Blue Clean thermal paper is approved for direct food contact and is renowned for its excellent printability, strength, readability and durability. The printed image lasts at least 35 years without fading and is available with many permanent and removable adhesives.
