Application and use
The surface of HERMAtherm top M offers an excellent quality of imprint with all conventional printing methods. Basically, suitability tests of inks should be performed prior to printing. Web temperature during curing should not exceed 50 °C in order to prevent premature imaging or discolouration.
Printing speeds of up to 200 mm/s are possible in thermal direct printing.
The phenolfree HERMAtherm top M can be used wherever thermo reactive labels of smudge-proof, solvent and grease resistant papers are required, e.g. for weight labels (meat packers, supermarkets) or for price marking labels (excellent suitability for EAN and UPC-codes). By reason that intensive contact with plasticizers might affect the thermal image, for applications on soft PVC films individual tests are recommended. Applications in humid surroundings are possible.
The pulp for this paper comes from FSC® certified forest management and other controlled sources.
