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.

Adhesive 62K is specially developed for deep-freeze application. Tack is very high on critical substrates like PE-films even at very low temperatures. 62K delivers an outstanding tack even on surfaces slightly covered by moisture or ice. At room temperature tack is extremely high on most surfaces. This supercalendered glassine is perfectly suited for assignment in labelling machines equipped with optical or mechanical scanners.

Processing

Excellent die-cutting characteristics on all usual machines. As part of a self-adhesive compound HERMA PH (515) offers excellent die-cutting characteristics with all customary flatbed and rotary die-cutting tools.

Storage conditions

Storing at a temperature of 20 ± 5 °C, a relative humidity of 45 ± 5 % and a dark storage is recommended. Moisture, heat and direct sunlight have to be avoided.

The shelf life is two years from date of production.

Regulations concerning contact with food

The thermal paper grade HERMAtherm top R (Grade 918) according to the sample material is physiologically and toxicologically safe and may therefore be used in printers and scales for the marking of goods. However, HERMAtherm top R may only have direct contact to foodstuffs which are washed and/or peeled before consumption (ISEGA Research and Development Institute, Aschaffenburg).

All ingredients of adhesive 62K comply with recommendation BfR XIV or FDA 21 CFR 175.105 (Adhesives).

The pressure-sensitive adhesive 62K can be safely used for the back coating of labels for the labelling of foodstuffs for storage at room temperature and below. It may be used in direct contact with dry and fatty foodstuffs that can be assigned a correction factor of at least 3 in accordance with Regulation (EU) No. 10/2011 provided that the ratio of contact surface related to the quantity of foodstuff does not exceed 1 dm²/kg. For the contact with moist foodstuffs, the ratio of contact surface related to the quantity of foodstuff is limited to 0,5 dm²/kg foodstuff. The contact with dry, non-fatty foodstuff is possible without restriction.Furthermore, the adhesive may be used for laminating various materials. In this case, cut edge contact with food is harmless as far as the above mentioned adhesive is concerned. It must be ensured that the relevant migration limits are complied with by the laminated packaging (Declaration of no objection valid until 06.04.2025).

The paper complies with recommendation BfR XXXVI.
