Application and use

HERMAtherm C 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 C 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 novel adhesive 82S is a permanent, water-activatable adhesive. It has been specially developed for applications on cardboard and comparable paper-like substrates. It is therfore particularly suitable for use in the logistics sector, e.g. as a shipping label and for marking on absorbent substrates.In combination with suitable dispensing equipment, typical labelling speeds of the print-and-apply sector can be achieved.

Processing

Can be processed on common printing and slitting machines.
Pre-tests should be carried out for water-based primers.

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 C (902) 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 pressure-sensitive adhesive 82S 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 and fatty foodstuffs in accordance with Regulation (EU) No. 10/2011. Furthermore, it may be used in direct contact with moist foodstuffs is permitted, provided that the ratio of the contact surface of the label related to the total weight of the food does not exceed 1 dm²/kg.
