Siegwerk Unveils Next Generation of Sustainable Water-Based Inks for Paper and Board Applications

Published: June 24, 2021

Siegwerk, one of the leading global providers of printing inks and coatings for packaging applications and labels, is now offering a new generation of sustainable water-based inks for paper and board applications: UniNATURE. The new product range is formulated with renewable and natural components, providing an environmentally friendly alternative to conventional inks without impacting the recyclability of paper, and board packaging taking a step towards reducing the microplastics which can be found in inks.

“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,” said Hanns Martin Kaiser, vice president business units paper & board EMEA and liquid food packaging, 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 reportedly formulated with a high Bio Renewable Content (BRC) measured according to the ASTM 6866 method. Products in the UniNATURE range reportedly incorporate up to 50 percent renewable carbon content – often 8 to 9 times more compared to standard water-based inks.

Siegwerk’s new sustainable water-based ink range comes along with excellent ink performance and color strengths offering similar levels of resistance as current water-based technologies. User tests have shown improved dot shape, comparable dot gain, high resolubility, and easy cleaning on press, meaning it can be easily exchanged with current products without the need to change equipment, processes or color matches.

Furthermore, 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 & board applications including corrugated board 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.
