SIG claims to have developed the world’s first aseptic carton pack with a clear link to 100% plant-based renewable materials.

The SIGNATURE PACK drives the replacement of conventional plastics from fossil fuels with certified and sustainable plant-based polymer materials. The polymers used for laminating the paperboard and making the spout originate from renewable European wood sources and are certified according to ISCC PLUS (International Sustainability & Carbon Certification) or CMS 71 (TÜV SÜD certification standard), respectively, via a mass balance system. This means that for the polymers used in the SIGNATURE PACK, an equivalent amount of bio-based feedstock went into the manufacturing of the polymers.

Ace Fung, Global Product Manager at SIG Combibloc: “Developing an aseptic carton pack fully linked to renewable plant materials is quite a challenge. Aseptic packages, where the product can be stored without refrigeration over a long period, have higher barrier requirements than chilled packages”.
