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.

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 one year from date of production.

Regulations concerning contact with food

For any food application the above mentioned thermal paper can be used together with a functional barrier to achieve a non-migration, the functional barriers tested for this purpose covering all the categories of foodstuffs for which the above mentioned thermal paper is likely to be used (biscuits, bakery, ice cream, confectionary, crisps & snacks, frozen & dry food, beverage powders, meat & gassing ripening cheese packaging). In any case, a direct contact is not foreseen.

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 05.05.2027).

The paper complies with recommendation BfR XXXVI.
