SIG announced a 24% year-over-year sales growth in 2025 for its alu-layer-free aseptic cartons, that reduce the already low CO2 footprint of standard SIG packs even further. This milestone marks another leap forward in the company’s ambition to create a regenerative food packaging system.
The sustained growth proves the market’s appetite for low carbon, recycle-ready packaging. Notably, beverage producers can adopt full barrier aseptic cartons without aluminum, seamlessly compatible with existing SIG filling lines, allowing for swift sustainability upgrades with minimal operational adjustments and no extra capital expenditure.
“Our commitment to scalable, impactful innovation is paying off – not just for SIG, but for our customer’s entire value chain,” stated Christoph Wegener, Chief Markets Officer at SIG. “The significant growth in our aseptic cartons without aluminum layer shows that our innovations in low-carbon packaging systems have gained broad-based commercial traction, and are not only helping brands, manufacturers, and retailers to confidently meet rapidly evolving regulatory and consumer expectations, but also to significantly advance their sustainability goals. Europe is spearheading the introduction with our SIG Terra solutions accounting for >10% of food packed in SIG aseptic cartons. Globally, they accounted for 5%. We look forward to expanding this share significantly in the near future.”
SIG’s packs are among the most sustainable packaging solutions in each relevant market segment1 – and the company is innovating to reduce its environmental impact even further. The flagship SIG Terra portfolio exemplifies the company’s relentless pursuit of sustainable innovation. This includes pioneering packaging materials without aluminum layers, polymers linked to forest-based and recycled feedstocks2, and next-generation recycle-ready bag-in-box and spouted pouch solutions.
Since launching the SIG Terra portfolio, SIG has delivered enough SIG Terra solutions across its portfolio of aseptic cartons, bag-in-box, and spouted pouches to fill around 7 billion liters of food, including almost 2 billion liters in 2025 alone. Double-digit growth in alu-layer-free aseptic cartons was driven by an expanded SIG Terra product range in Europe and the global ramp-up of the SIG Terra Alu-free + Full barrier packaging material, marking a major milestone in sustainable innovation.
SIG’s continued sustainable innovations are transforming industry standards, validating the commercial viability of truly sustainable packaging, and paving the way for widespread industry adoption. As the sector moves from ambition to scale, SIG’s sustainability progress is leading by example.
