SIG has formed a partnership with PulPac, a company specialising in Dry Molded Fiber technology, to work on the development of paper-based closures for its aseptic cartons.<\/p>\n

<\/p>\n

This initiative is part of SIG\u2019s broader objective to increase the paper content in its packaging to 90% by 2030.<\/p>\n

SIG chief technology officer Gavin Steiner said: \u201cWe believe in Dry Molded Fiber technology, paving the way for innovative and responsible alternatives to plastic closures.<\/p>\n

\u201cIt is one of the most scalable fibre-based solutions on the market with great potential to boost progress in the transition from plastic to paper-based closures. In our paper-based closure, both the base and the cap will be paper-based \u2013 significantly increasing the already very high proportion of paper in our aseptic cartons.<\/p>\n

\u201cAt the same time, we aim to offer consumers the same convenience and first-class opening performance they associate with our existing closure solutions.\u201d<\/p>\n

The collaboration aims to enhance the sustainability of SIG\u2019s aseptic cartons by raising the paper content, thereby reducing reliance on fossil-based materials and lowering carbon emissions.<\/p>\n

For the current year, SIG has set a goal of achieving 85% paper content in its packaging, excluding closures.<\/p>\n

PulPac\u2019s technology involves creating a dry web of fibres, which reduces water consumption during production and results in lower carbon emissions compared to conventional plastic methods.<\/p>\n

This approach also allows for greater design flexibility and supports large-scale manufacturing.<\/p>\n

In the context of SIG\u2019s aseptic cartons, closures are applied after the filling process, ensuring that the products remain secure within the aseptic environment.<\/p>\n

SIG chief markets officer Christoph Wegener said: \u201cFor packaging innovations focused on sustainability to have a significant impact, they must be compatible with the installed machinery setup.<\/p>\n

\u201cThat is why \u2018plug-and-play\u2019 solutions are an absolute design principle for us at SIG, which we inherently follow across our unique packaging structures without [an] aluminium layer. We apply the same approach to our paper-based closures.<\/p>\n

\u201cThe combination of aluminium-layer-free packaging materials and paper-based closures will be our path to 90% paper content in our full-barrier aseptic cartons. This would be a real breakthrough in the packaging industry toward a circular economy.\u201d <\/p>\n

Earlier this month, SIG unveiled<\/a> one-litre aseptic carton packs made from the Terra Alu-free + Full barrier material, omitting the aluminium layer.<\/p>\n
