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.

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 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 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.
