Bio-compostable label with their adhesive – Herma

Two HERMA adhesive/label combinations awarded the so-called Keimling (seedling) logo, as certification according to EN 13432, has been completed.

We cannot avoid the waste; it should at least be recyclable or reused or a proper landfill for composting. Considering its sustainable strategy, HERMA labeling division has now enhanced a further step in this direction. The label properties are consisting of the label substances with bi-composting grade.

Bio-compostable labels following are: – 

Label Material – HERMAextracoat (grade 242) or HERMAtherm Bio (grade 908) 

Adhesive –  special adhesive label grade 62N 

The adhesive awarded the so-called Keimling (seedling) logo. It is like certification, according to EN 13432, which has been completed. The standard globally acknowledged benchmark for the industrial compostability of biodegradable products. 

HERMA is covering the way for the complete composting of packaging, including all labels. 

HERMAextracoat comes with white, adhesive label paper, which is semi-gloss coated on one side, and Programme for the Endorsement of Forest Certification-certified. It is proper for manufacturing advanced labels that are compatible with multicolor offset/gravure/flexo printing with all the traditional methods. 

HERMAtherm Bio is an eco-quality thermal paper. The pulp for the paper originates from FSC-certified forestry. 

The certification for the self-adhesive is per the standard of DIN CERTCO (Composting standard) and this company belongs to TÜV Rheinland Group.

“Those who want to do compostable packaging – including all substances made of suitable bioplastics – no longer have to forego the performance advantages of labeling,” says Dr. Ulli Nägele, HERMA’s head of development.

Bio-Compost label straight suitable for agricultural purposes

For certification to EN 13432, both goods had to meet strict standards. After composting for three months and can cross through a 2 mm sieve. For example, Final substances will not be more than 10% of the initial mass.

The certification method also requires an analysis of the resulting compost’s effect on seedling growth, which means its ecotoxicity. 

Compost or humus generated from certified materials can, therefore, used straight for agricultural purposes. In the case of industrial composting, as conceived by EN 13432, compared with backyard composting. The degradation methods take place much more swiftly – within around 12 weeks sooner than many months – because of the higher temperatures and additional factors.
