Application and use
The surface of HERMAtherm F offers excellent quality of the imprint with all traditional printing methods. Basically, suitability tests of inks should be performed prior to printing. Web temperature during curing should not exceed50 °C in order to prevent premature imaging or discolouration. Due to the lack of reverse coat, labels should not be applied on surfaces containing plasticisers. Recommended for moistly and dry applications.
Printing speeds of up to 300 mm/s are possible in thermal direct printing.
HERMAtherm F is universally applicable wherever thermo reactive labels of smudge-proof, solvent and grease resistant paper are required, e.g. weight labels (meat packers, super-markets) or price marking labels (excellent grades with EAN and UPC-codes).
The pulp for this paper comes from FSC certified forest management and other controlled sources.
