Application and use
The surface of HERMAtherm P offers an excellent quality of the imprint with all traditional printing methods. In general, suitability of all printing inks should be tested prior to printing. Web temperature during curing should not exceed 50 °C in order to prevent an early reaction of the thermo reactive ink.
Printing speeds of up to 200 mm/s are possible in thermo direct printing.
HERMAtherm P is Bisphenol-free and can be used wherever thermo reactive labels of smudge proof, solvent and grease resistant paper are required, e.g. for weight labels (meat packers, supermarkets) or for price marking labels (excellent presentation of EAN and UPC codes). Applications on surfaces containing plasticizers are only partially possible. By reason that intensive contact with plasticizers might reduce the sensitivity of the thermo reactive coating and might cause a fading of the printed image, for applications on soft PVC films individual tests are recommended.
The pulp for this paper comes from FSC® certified forest management and other controlled sources.
