Grass – or rather sun-dried hay, to be specific – is a major component of what may well be the world‘s most eco-friendly label paper. Processing these fibers for paper production is very resource-friendly and generates very little CO₂, compared with paper produced from fresh fiber or even recycled cellulose.

Since 2017, grass papers have been widely used for various kinds of food packaging and have received a lot of attention from companies committed to sustainable packaging. Made from grass paper, the new label material HERMAnature fieno (grade 340) allows users to also apply special sustainability requirements to labels. The production of such grass papers is based on special grass pellets developed and patented by a German company.

 In this process, grass fibres are processed mechanically, requiring no chemicals. Compared to wood pulp processing, this results in energy savings of 97 percent and water savings of 99 percent. As the grass originates from domestic areas, logistics expenses are also minimized, resulting in CO₂ savings of up to 75 percent. In the end product grass paper, CO2 savings amount to a considerable sum of 20 to 25 percent.

Excellent printability

The new label material HERMAnature fieno contains 30 percent% of this very sustainable resource. In principle, it can be processed like conventional paper and offers very good printability in offset and flexo printing.

“As it is a natural product, its color can vary”, says Dr. Ulli Nägele, Head of Research and Development at HERMA. “But combined with the material’s somewhat rougher surface, this immediately and credibly signals to the consumer that this is sustainable packaging material.”

An additional advantage: the grass paper contains no allergens that are subject to EU labelling requirements listed in the regulation (EU) 1169/2011, such as fish or nut products. Therefore, grass paper labels are ideally suited for use with food and cosmetics. In order to maintain this advantage, HERMAnature fieno is equipped with the 62A adhesive which is suitable for direct contact with dry and moist foodstuffs as well as fatty foodstuffs with a correction factor of 3 or more according to the regulation (EU) 10/2011. Apart from that, the 62A adhesive is a permanent adhesive for universal use with very good adhesive properties on a wide range of surfaces.
