Siegwerk, a provider of printing inks and coatings for packaging and labels, has introduced a new nitrocellulose (NC)-free toolbox designed to facilitate the creation of recyclable flexible packaging.<\/p>\n

<\/p>\n

The NC-free toolbox aims to help the company\u2019s customers meet the latest recycling criteria while maintaining packaging performance for polyolefin (PO) solutions.<\/p>\n

The solution combines Siegwerk\u2019s existing NC-free ink portfolio with new developments, offering solutions for both lamination and surface applications in gravure and flexographic printing.<\/p>\n

Initially available in the Europe, Middle East and Africa region, the toolbox enables the realisation of recyclable flexible packaging across various application segments.<\/p>\n

It includes a full range of colours and overprint varnishes for gravure and flexo printing applications.<\/p>\n

All solutions within the toolbox comply with current recycling guidelines and are offered as ready-to-use inks or as a masterbatch system.<\/p>\n

Siegwerk\u2019s proprietary polyurethane resin technology, which replaces NC, is a key enabler for this new offering.<\/p>\n

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

Organisations such as RecyClass and the German minimum standard have updated their regulations to limit NC content in PO-based packaging structures.<\/p>\n

The launch of the NC-free toolbox for flexible packaging represents a step forward in meeting the growing demand for circular packaging designs that yield high-quality recyclate and adhere to the latest Design for Recycling guidelines.<\/p>\n

In December last year, Siegwerk expanded its CIRKIT range<\/a> with coatings to boost packaging recyclability and reusability.<\/p>\n

The company said that these coatings maintain key functionalities such as barriers and sealability while supporting circular economy principles.<\/p>\n
