Siegwerk launches NC-free toolbox for recyclable packaging

Siegwerk, a provider of printing inks and coatings for packaging and labels, has introduced a new nitrocellulose (NC)-free toolbox designed to make it easier to create flexible, recyclable packaging.

The NC-free toolbox aims to help the company’s customers meet the latest recycling standards while maintaining the packaging performance of their polyolefin (PO) solutions.

This solution combines Siegwerk’s existing NC-free ink range with new developments, providing solutions for both lamination and surface applications in gravure and flexographic printing.

The toolbox, which was initially available in the EMEA region, makes it possible to achieve flexible, recyclable packaging across different application sectors.

Includes a full range of colors and overprint varnishes for gravure and flexo printing applications.

All solutions in the toolbox comply with current recycling guidelines and are offered as ready-to-use inks or as a master system.

Siegwerk’s proprietary polyurethane resin technology, which replaces NC, is a key enabler of this new offering.

Although NC-based inks have been widely used due to their high resistance, fast drying, and excellent adhesion, they pose challenges for material recycling.

Organizations such as RecyClass and the German Minimum Standard have updated their regulations to limit NC content in PO-based packaging structures.

The launch of the NC-free toolkit for flexible packaging represents a step forward in meeting the growing demand for circular packaging designs that produce high-quality recycling and adhere to the latest design guidelines for recycling.

In December last year, Siegwerk It has expanded its CIRKIT range With coatings to enhance packaging recyclability and reuse.

The company said these coatings maintain key functions such as barriers and sealability while supporting circular economy principles.
