Application and use
The surface of HERMAtherm top R 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.
HERMAtherm top R is phenolfree and 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 grades with EAN and UPC-codes). Due to lacking a reverse coat, labels should not be applied on surfaces containing plasticisers. Applications in humid surroundings are possible. Should a reverse coat be required, e.g. for applications on surfaces containing plasticisers, we recommend our standard top qualities HERMAtherm P or HERMAtherm D.
The pulp for this paper comes from FSC® certified forest management and other controlled sources.
