Werner & Mertz, Mondi and Siegwerk have partnered to develop a circular-economy-capable stand-up pouch. The product received a gold status in all categories for its recyclability with the Cradle-to-Cradle (C2C) certification.
Siegwerk supports and enables circular packaging in several initiatives, contributing know-how from the printing ink perspective to make packaging recyclable and more sustainable. One example is the cooperation with Werner & Mertz's Recyclate Initiative. Siegwerk is one of the key partners within this initiative. The company developed ink technologies for several applications and substrates.
‘C2C presents a well-accepted and scientifically proven method to validate the characteristics of sustainable materials, products and systems by putting a major role on the human and ecological health impact of the chemical substances used as constituents. With C2C, brand owners have the opportunity to demonstrate their innovation efforts to keep their sustainability promise,’ said Dr Stefan Häp, head of technology and innovation for brand owner collaboration at Siegwerk.
‘The pouch development shows that sustainable products cannot be rushed,’ added Immo Sander, head of packaging development at Werner & Mertz. ‘They need time, investment, innovation and close cooperation among all partners along the entire value chain if they are to be truly recyclable in the end.’
‘We took care of the initial ignition for the sustainable inks on self-adhesive labels and on films for pouches,’ said Dr Häp. ‘For this purpose, Siegwerk developed special ink systems that fit into the certified environmentally friendly concept and the sustainability strategy of Werner & Mertz as well.’
