Application and use

HERMAtherm Bio phenol-free suits well as label material on food packaging and gives ex-cellent 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 Bio phenol-free offers a good quality of imprint when solventfree inks and varnishes are applied. The inks should be suitable for printing thermal papers. 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 pressure-sensitive adhesive 62Q has been specially developed for direct food labelling. In addition, Adhesive 62Q can also be used on compostable packaging materials. Slight condensation on the packaging film should not present a problem.

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

The self-adhesive material has been certified as compostable materials for home and garden composting (2021-2) by DIN CERTCO GmbH according to NF T51-800:2015. The certificates are valid until 31.01.2029.

Processing

The die-cutting properties are good on all conventional machines.

As part of a self-adhesive compound HERMA PW (520) 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 Bio phenol-free (909) 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).

All ingredients of the pressure sensitive adhesive 62Q comply with the recommendations BfR XIV or FDA 21 CFR 175.105 (Adhesives).

The pressure-sensitive adhesive 62Q 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 2 in accordance with Regulation (EU) No. 10/2011 (Declaration of no objection valid until 17.01.2025).

The paper complies with recommendation BfR XXXVI.
