SIG industrializes its aluminum-free full-barrier aseptic cartons in France with LSDH

October 2026 marks a definitive transition for aseptic packaging in the French market. SIG has officially industrialized its aluminum-free, full-barrier aseptic carton technology in France, partnering with the LSDH Group (Laiterie de Saint-Denis-de-l'Hôtel) and its subsidiary Jus de Fruits d'Alsace (JFA).

The SIG Terra Alu-free + Full barrier packaging material is not entirely new to the sector, having debuted in 2025 for multi-serve formats in Italy. However, its deployment at JFA's facilities represents the critical leap from early adoption to mainstream industrial scale in one of Europe's most demanding beverage markets. Moving from pilot runs to full commercial production with a major co-packer confirms the operational maturity of the barrier technology.

Technical execution and material structure

The structural shift in these cartons involves eliminating the traditional aluminum foil layer, which has historically been essential for ambient liquid packaging. SIG replaces this with an ultra-thin polymer coating that provides equivalent protection against oxygen, light, and moisture. This modification increases the paperboard content of the carton to over 80%.

From a sustainability and supply chain perspective, reducing the raw materials from three to two simplifies the recycling process and lowers the carbon footprint of the multi-serve cartons by up to 61% compared to standard formats. For a contract manufacturer like LSDH, integrating this material requires seamless compatibility with existing infrastructure.

• Drop-in compatibility: The material runs on installed SIG aseptic fillers without requiring extensive mechanical overhauls.
• Production speed: JFA maintains high-speed output, crucial for multi-serve juice and dairy alternative lines.
• Shelf life: The full-barrier properties guarantee the standard 12-month ambient shelf life required by retail networks.

Market implications for European co-packing

The commercial launch out of France signals that the supply chain for high-barrier, aluminum-free paperboard is now robust enough to support top-tier European contract packers. LSDH's adoption provides a blueprint for other manufacturers looking to transition their aseptic lines without sacrificing throughput or product safety.

As the packaging industry pushes toward a 90% paper content target by 2030, SIG's execution with LSDH and JFA proves that the technical hurdles of replacing aluminum in long-life liquid packaging have been definitively cleared at an industrial scale. The focus now shifts from material viability to widespread capacity deployment across the continent.
