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.
HERMAtherm Bio phenol-free is specially developed to meet the requirements of EN 13432. In combination with the HERMA adhesive 62E it was tested for compostability under industrial conditions (EN 13432) and was awarded the "Seedling" logo.
In combination with the pressure-sensitive adhesive 62Q HERMAtherm Bio phenol-free (909) has been certified as compostable 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.
