“UniNATURE is our third generation of sustainable water-based inks and coatings for paper and board applications meeting the requirements of brand owners and packaging converters,” says Hanns Martin Kaiser, Vice President Business Units Paper & Board EMEA and Liquid Food Packaging at Siegwerk. “With its launch we again deliver on our commitment to enabling the development of new packaging innovations in line with a circular economy.”
The new water-based ink and coating solutions are formulated with a high Bio Renewable Content (BRC) measured according to the ASTM 6866 method. Products in the UniNATURE range incorporate up to 50% renewable carbon content – often 8 to 9 times more compared to standard water-based inks. High printing speeds runs on both coated and uncoated papers can be achieved with UniNATURE. The new ink and coating series is applicable for many paper and board applications including corrugated boxes, trays and displays, fast food packaging, sacks and bags, as well as cups and wraps. It supports various printing applications whilst meeting the highest market and regulatory standards.
“Paper is not only already one of the most recycled packaging materials globally, but it also holds great potential to offer a viable substitution for plastic for several packaging uses,” explains Paul Pain, Head of Waterbased Technology at Siegwerk. “And with UniNATURE we concretely support the defossilisation of fibre-based packaging by reducing the use of fossil based raw materials in inks.”
Together with Siegwerk’s sustainable and functional barrier coatings, UniNATURE forms a solution for the development of innovative and circular fibre-based packaging solutions. With the Finnish paper and paperboard manufacturer Kotkamills, Siegwerk has already been able to prove the high performance of UniNATURE utilized on a fully recyclable paper cup made of Kotkamills’ innovative ISLA® Duo barrier board – to just name one best practice usage of the newly launched product series.
