Application and use

The surface of HERMAtherm P offers an excellent quality of the imprint with all traditional printing methods. In general, suitability of all printing inks should be tested prior to printing. Web temperature during curing should not exceed 50 °C in order to prevent an early reaction of the thermo reactive ink.

Printing speeds of up to 200 mm/s are possible in thermo direct printing.

HERMAtherm P is Bisphenol-free and can be used wherever thermo reactive labels of smudge proof, solvent and grease resistant paper are required, e.g. for weight labels (meat packers, supermarkets) or for price marking labels (excellent presentation of EAN and UPC codes). Applications on surfaces containing plasticizers are only partially possible. By reason that intensive contact with plasticizers might reduce the sensitivity of the thermo reactive coating and might cause a fading of the printed image, for applications on soft PVC films individual tests are recommended.

The pulp for this paper comes from FSC® certified forest management and other controlled sources.

Thanks to its extremely high adhesion adhesive 64B is particularly suitable for labelling strongly curved, rough, dusty or oily surfaces as well as rubber products and containers for chemicals. In combination with HERMA PE laser this adhesive is suitable for labelling chemical barrels after filling them at a maximum temperature of 180 °C.In spite of its high coating weight this newly designed adhesive offers excellent die-cutting characteristics. Adhesive 64B is particularly resistant to light, heat and ageing.

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

Processing

Good 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 P (Grade 923) 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 P 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 64B comply with recommendation FDA 21 CFR 175.105 (Adhesives).

The pressure-sensitive adhesive 64B 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 5 in accordance with Regulation (EU) No. 10/2011. Furthermore, the adhesive may be used for laminating plastic films. In this case, cut edge contact with food is harmless as far as the above mentioned adhesive is concerned (Declaration of no objection valid until 14.03.2026).

The paper complies with recommendation BfR XXXVI.
