HERMA
New adhesive for biodegradable laminates

06.03.2023 Industrial composting of labels in accordance with EN 13432 has been possible for some time thanks to HERMA adhesive material. Now, however, even home and garden composting can be easily realised.

Good for the environment: with the new HERMA 62Q pressure-sensitive adhesive, corresponding labels are also suitable for home and garden composting in accordance with the international standard NF T51-800:2015.

Good for the environment: with the new HERMA 62Q pressure-sensitive adhesive, corresponding labels are also suitable for home and garden composting in accordance with the international standard NF T51-800:2015.

HERMA's new 62Q adhesive, in conjunction with two label materials, has passed the relevant certification by DIN CERTCO in accordance with the internationally valid NF T51-800:2015 standard. They are "DIN tested - garden compostable". This means: Even fruit peels or vegetable scraps that still have a corresponding label on them can be disposed of by end consumers on their own compost heap or in their own composter. The labels will biodegrade there without leaving any harmful substances behind. Equipped with the 62Q pressure-sensitive adhesive, these labels are not dependent on the optimal conditions and high temperatures of industrial composting.

Easy to die-cut, good adhesion

At the same time, the labelstock is very easy to die-cut in the printing process and the pressure-sensitive adhesive features good adhesion. "To our knowledge, we are one of the first labelstock suppliers in the world to offer such certification for labels in combination with excellent processability and adhesion," says Harald Wallner, Director Sales International at HERMA. The introduction comes at exactly the right time: individual countries such as France and Australia have already started or announced to require corresponding proofs for packaging and labelling materials. For labels that require proof of industrial compostability, HERMA offers the 62E adhesive. It convinces with similarly good die-cutting and adhesive properties; two label materials equipped with it are allowed to carry the so-called seedling logo according to EN 13432.

Wide range of applications

Both adhesives were certified in combination with the label materials HERMAextracoat (grade 242) and HERMAtherm Bio (grade 909). HERMAextracoat is a white, one-sided, slightly glossy coated adhesive label paper made of FSC Mix Credit material. It can be used to produce visually sophisticated, multi-coloured labels in all classic printing processes. Despite its compostability, self-adhesive material produced with it is just as high-quality to print on and just as easy to die-cut as conventional self-adhesive material. HERMAtherm Bio (grade 909), on the other hand, is a white phenol-free thermal paper without protective coatings, i.e. an economy quality, but also made from FSC Mix Credit material. It is ideal for the weighing area of food packaging; EAN codes and other code systems can be displayed very well on it.
