The solution replaces the traditional [aluminum layer found in carton-style packaging](https://www.trendhunter.com/trends/all-day-allergy-relief) 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](https://www.trendhunter.com/trends/avantium)." ## Trend Insights (Trend Hunter) - Score: 5.6/10 - Popularity: 60% | Activity: 67% | Freshness: 41% - Audience gender: 50% men, 50% women - Primary generations: Millennial, Gen X - Top markets: North America ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Eco](https://www.trendhunter.com/eco) ## Key Themes ### Key Themes Behind This Trend - **Aluminum-free Packaging:** The transition to aluminum-free packaging highlights an innovation in reducing carbon footprints for aseptic beverage cartons significantly. - **Sustainable Beverage Containers:** This trend focuses on using over 80% paper in beverage containers to drastically lower carbon emissions compared to traditional packaging solutions. - **Plant-based Product Packaging:** An opportunity arises in the packaging of sensitive product categories like plant-based beverages without relying on traditional aluminum barriers. ### Where This Applies - **Eco-friendly Packaging Industry:** Innovations in eco-friendly packaging, such as aluminum-free aseptic cartons, present a shift towards more sustainable material use. - **Beverage Industry:** As the beverage industry adopts new packaging solutions, a significant reduction in packaging-related carbon footprints can be achieved. - **Plant-based Foods and Beverages:** The growing plant-based foods and beverages sector can benefit from sustainable packaging that preserves product integrity without aluminum. ## Related on Trend Hunter - [Aluminum-Free Juice Packaging](https://www.trendhunter.com/trends/signature-evo.md) - [Paper-Based Barrier Drink Packaging](https://www.trendhunter.com/trends/tetra-pak-and-sterilgarda-alimenti.md) - [Aseptic Eco Beverage Packaging](https://www.trendhunter.com/trends/tetra-brik-aseptic-200-slim-leaf-carton.md) - [Paper-Made Juice Packaging](https://www.trendhunter.com/trends/tetra-brik-aseptic.md) - [Sustainable Carton-Style Packaging](https://www.trendhunter.com/trends/elopak-paperboard.md) - [Recyclable High-Barrier Packaging](https://www.trendhunter.com/trends/sappi-paper-packaging.md) - [Recyclable Paper Confectionery Packaging](https://www.trendhunter.com/trends/recyclable-paper-confectionery-packaging.md) - [Plant-Based Milk Packaging](https://www.trendhunter.com/trends/plant-based-milk-packaging.md) - [High-Barrier Paper Packaging Platform](https://www.trendhunter.com/trends/highbarrier-paper.md)
