In particular, the crop grown from seeds branded Donau-Silphie has been converted into an energy source in its entirety thus far, but Herma is now nurturing an option for the plants’ fibers. These fibers are separated in a biothermal process before the energy generation phase and then converted into a new regional and sustainable raw material.
Labels made with the paper are suitable for printing without any further treatment. Embossing and other embellishment can be used to add sophistication while retaining a natural look because individual fibers of the cup plant remain visible in the material. This texture also serves as a visual acknowledgment to the paper’s sustainability. The labelstock incorporates the Herma UVA adhesive 63B, a versatile material offering excellent adhesive properties.
The stock is available in quantities from just 1,000 square meters. Using the labelstock HERMAsilphie (grade 341), Etiket Schiller has now become the first printer in Germany to start producing cup plant labels.
“This new material, made entirely in Germany, enables us to extend our environment-friendly portfolio in a focused way,” comments Etiket Schiller managing director Susanne Daiber. “Our customers now have access to a further highly appealing green packaging option for cosmetics, beverages and food.”
The proportion of cup plant fibers in the label material is currently at least 35%, but in the future it can be raised to 50%. This curbs the labels’ CO2 footprint by reducing the share of imported wood pulp, which is mostly sourced from distant countries. In addition, cup plant labels can be recycled in the regular waste paper streams. Cup plants, or their fibers, have been used successfully for a long time in the production of folding boxes.
