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 62Dps shows good adhesion specially on packaging films, also at low temperatures. Due to the very high initial tack 62Dps is particularly well suited for high-speed dispensing systems. Because of its multi-layer construction 62Dps shows extremely low tendency for migration and is suitable for direct contact also with fatty foodstuff with limitation (correction factor). 62Dps is less suitable for curved surfaces.

The adhesive has a good aging, heat and light resistance.

This supercalendered glassine is perfectly suited for assignment in labelling machines equipped with optical or mechanical scanners.

Processing

Excellent die-cutting characteristics on all customary 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

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 62Dps comply with recommendation BfR XIV or FDA 21 CFR 175.105 (Adhesives).

The pressure-sensitive adhesive 62Dps 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, moist and fatty foodstuffs that can be assigned a correction factor of at least 3 in accordance with Regulation (EU) No. 10/2011. 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 27.09.2025).

The paper complies with recommendation BfR XXXVI.
