Image: SIG reported a remarkable 24% year-over-year sales growth in 2025 for its alu-layer-free aseptic cartons. These advanced cartons further minimize the already low CO2 footprint associated with standard SIG packaging. This significant achievement represents yet another advancement in the company’s mission to establish a regenerative system for food and drink packaging.
In 2025, SIG announced a substantial 24% increase in sales for its alu-layer-free aseptic cartons, reinforcing its commitment to eco-friendly food and drink sustainable packaging. This milestone illustrates significant progress toward reducing the environmental impact of packaging solutions.
The consistent growth highlights the market’s demand for low carbon, recyclable packaging options. Importantly, beverage producers can adopt full barrier aseptic cartons without aluminum, which are fully compatible with SIG’s existing filling lines. This compatibility allows for swift upgrades in sustainability with minimal operational changes and no additional capital investment.
“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 an aluminum layer shows that our innovations in low-carbon packaging systems have gained broad-based commercial traction. These advancements not only help brands, manufacturers, and retailers respond to evolving regulatory and consumer expectations but also significantly promote their sustainability objectives. Europe is leading this initiative, with our SIG Terra solutions accounting for over 10% of food packaged in SIG aseptic cartons, while globally, they comprise 5%. We anticipate a substantial increase in this share moving forward.”
Among various market segments, SIG’s packaging solutions rank as some of the most sustainable options available1. The company continuously innovates to further reduce its environmental impact. The renowned SIG Terra portfolio epitomizes SIG’s unwavering dedication to sustainable packaging innovation. This includes developing packaging materials that eliminate aluminum layers, as well as polymers derived from forest-based and recycled feedstocks2, along with next-generation recycle-ready bag-in-box and spouted pouch solutions.
Since the introduction of the SIG Terra portfolio, SIG has successfully deployed enough SIG Terra solutions across its aseptic carton, bag-in-box, and spouted pouch lines to fill approximately 7 billion liters of food, nearly 2 billion liters of which were achieved in 2025 alone. The double-digit growth in alu-layer-free aseptic cartons was propelled by an expanded SIG Terra product range in Europe and the global introduction of SIG Terra Alu-free + Full barrier packaging material, marking a landmark achievement in sustainable innovation.
SIG’s ongoing innovations are reshaping industry standards, demonstrating the commercial viability of genuinely sustainable food and drink packaging, and facilitating widespread adoption across the industry. As the sector transitions from ambition to implementation, SIG’s sustainability efforts set a noteworthy example.
