This SIG aluminum-free full barrier solution has been announced by the packaging specialist as an innovation for multi-serve aseptic beverage cartons as a way to reduce their carbon footprint. The solution replaces the traditional aluminum layer found in carton-style packaging that usually accounts for 5% of the design, but accounts for as much as 25% of its overall carbon footprint. The new layer is made with more than 80% paper and will reportedly cut the carbon footprint of standard carton packaging by as much as 61%.

Chief Markets Officer Christoph Wegener spoke on the SIG aluminum-free full barrier solution saying, “With our full barrier material with no aluminum layer, we are offering a powerful differentiator and embodiment of sustainability in aseptic carton packaging, unlocking new opportunities for packaging sensitive product categories such as plant-based products, juices, and nutritional beverages.”
