Application and use
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.
Direct thermal printing is possible with speeds up to 250 mm/s.
The material can be printed by all conventional roll printing methods. The inks should be suitable for thermal paper (solvent-free), a consultation of the ink supplier is recommended. Complete curing of the ink must be ensured. Due to the thermal sensitive characteristic the web temperature during curing should not exceed 50 °C. In general, it is advisable to carry out pretests under customer-specific conditions to ensure suitability.
The pulp for this paper comes from FSC® certified forest management and other controlled sources.
