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.

Adhesive 42Rpp offers good tack combined with excellent removability from most surfaces, even after long-term labelling. Thanks to its well-balanced adhesive characteristics this removable adhesive is pe rfectly suited for a wide variety of applications. However, the low adhesion of 42Rpp is likely to be insufficient for applications on curved surfaces.The adhesive is resistant to light, heat and ageing.

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 one year 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).

The pressure-sensitive adhesive 42Rpp 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 4 in accordance with Regulation (EU) No. 10/2011.
