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.

The adhesive 62P is designed for applications where the label has to be removed without residue. Good results can be reached from 35 °C.

The washing time depends on the label material, the substrate on which the label is applied, the printing and the washing parameters as water temperature, water pressure and the used washing additives.

The adhesive shows good results on PE and PP reusable boxes and buckets, which are also used at low temperatures.

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

Processing

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.

The adhesive 62P may be used safely for the reverse coating of labels for the labelling of food stored at room temperature and below. It may stand in direct contact with ddry, non-fatty food, provided that the ration of the contact surface of the label related to the total weight of the food does not exceed 0,1 dm²/kg. (Declaration of no objection valid until 04.05.2025).

The paper complies with recommendation BfR XXXVI.
