Application and use

HERMAtherm G BPA-free is Bisphenol A free and suits well as label material on food packaging and gives excellent representation of EAN and other barcodes.

As economy thermal papers are not equipped with a protective surface coat, they should not be exposed to water or greasy substances. The image may fade over a period of time if applied to surfaces containing plasticisers (e.g. flexible polyvinyl chloride).

Printing speeds of up to 250 mm/s are possible in thermal direct printing.

The surface of HERMAtherm G BPA-free offers a good quality of imprint when solvent-free inks and varnishes are applied. The inks should be suitable for printing thermal papers, consulting of ink supplier is recommended. Basically, suitability tests should be performed under customer-specific conditions as unpredictable interactions with the ink may occur due to the lack of a protective coating.

Web temperature during curing should not exceed 50 °C in order to prevent premature imaging or discolouration.

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

The thermal paper grade HERMAtherm G BPA-free (907) 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, they may only stand in direct contact with those foodstuffs which are washed and/or peeled before consumption (ISEGA Research and Development Institute, Aschaffenburg).

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.
