24 % sales growth: SIG’s alu-layer-free aseptic cartons gained widespread adoption in 2025

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.

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.
