Siegwerk’s packaging ink series
Uninature, Siegwerk’s packaging ink series, is a sustainable water-based ink range for paper and board applications. Siegwerk says it is formulated with natural components. As a result, it partly replaces fossil carbon with bio-renewable carbon. The company adds this concretely contributes to defossilisation in the sense of a circular economy
Siegwerk says Uninature incorporates up to 50 per cent renewable carbon content. It says this is up to nine times more compared to standard water-based inks. Therefore it provides an environmentally friendly alternative to conventional inks, according to Siegewerk. Also, it does not impact the recyclability of paper and board packaging and contributes to reducing micro-plastics in inks. A combination of natural and conventional resins, from bio-sourced monomers, allows customers to quickly change to Unnature. It requires no adjustments to the existing processes, such as speed and colour matching.
Furthermore, the sustainable ink range comes along with excellent ink performance, according to the company. It adds that colour strengths offer similar levels of resistance as current water-based technologies. Siegwerk says it offers an improved ink stability and lower VOC content. Also, it enables high printing speeds on coated and uncoated papers. Uninature has application for corrugated board boxes, trays, displays, fast food packaging, sacks, bags, cups and wraps. It supports various printing applications whilst meeting market and regulatory standards.
