Siegwerk introduces NC-free toolbox for design of recyclable flexible packaging solutions

Siegwerk enables its customers to create future-proof flexible polyolefin packaging solutions

  • By ICN Bureau | January 22, 2025

Siegwerk, one of the leading global providers of printing inks and coatings for packaging applications and labels, today announced the launch of an NC-free toolbox bundling all its nitrocellulose (NC) free ink solutions for flexible packaging applications.

The new offering combines new developments with Siegwerk’s proven NC-free ink portfolio and includes solutions for lamination as well as surface applications in gravure and flexo printing. The toolbox is designed to enable customers and brand owners – initially in the EMEA region – to realize recyclable flexible packaging across the full-range of application segments.

“Focused on further improving packaging recyclability in the sense of a Circular Economy, the packaging regulatory landscape is continuously evolving, particularly in the European Union. In this context, packaging structures with NC-based inks are getting increasingly under pressure,” explains Dr. Björn Ewig, Head of Technology Flexible Packaging EMEA at Siegwerk.

Although inks based on nitrocellulose offer many advantages such as high resistance, fast drying and excellent adhesion, which has made them a common solution in packaging printing for a long time, they can also significantly hinder the material recycling process.

 “The new set of ink series in the toolbox is a milestone in the development of NC replacement. They are based on a new generation of polyurethane (PU) resins that, for example, give them much better surface resistance. This enables our customers to realize NC-free flexible packaging that is not only recyclable but also offers comparable high packaging performance in lamination and surface applications,” adds Ewig.
