Two adhesive laminates from Herma have now been awarded the so-called Keimling mark, as certification in accordance with EN 13432 has been successfully completed.
This standard is a Internationally recognised proof of industrial compostability of biodegradable products. This makes it possible to design complete packaging, including labels, to be compostable. This was certified Label material Hermaextracoat (variety 242) and. Hermatherm Bio (grade 908) and the special Pressure-sensitive adhesive 62N.
Hermaextracoat is a white adhesive label paper with a slightly glossy coating on one side that is PEFC-certified. It is suitable for for sophisticated labels with multi-colour printing in all classic printing processes. Hermatherm Bio is a Eco-quality thermal paper, whose pulp comes from FSC-certified forestry. The certification of the entire adhesive composites in accordance with the composting standard was carried out according to DIN CERTCO, the certification organisation of the TÜV Rheinland Group.
„Anyone who wants to use compostable packaging - including that made from corresponding bioplastics products - no longer has to forego the benefits of efficient labelling,“ says Dr Ulli Nägele, Head of Development at Herma Haftmaterial.
Compost immediately usable in agriculture
To optimise the Certification according to EN 13432 both products had to fulfil strict criteria. For example, after three months of composting and subsequent sieving through a 2 mm sieve no more than ten per cent residues remain in relation to the original mass. However, the effect of the resulting compost on plant growth is also analysed in the course of certification, i.e. ecotoxicity. Compost or humus obtained in this way can therefore be used directly in agriculture. With a industrial composting, As a result, the processes - compared to garden composting - are significantly accelerated due to higher temperatures, among other things, and only take about 12 weeks instead of many months.
