Constantia Flexibles wins two WorldStar Awards for ComforLid aluminum lidding solution
Recognition in “Packaging Materials & Components” and “Non-Alcoholic Beverages” categories
Vienna, January 22, 2026
Constantia Flexibles has received two WorldStar Awards for its aluminum lidding solution ComforLid in the categories “Packaging Materials and Components” and “Non-Alcoholic Beverages.” The awards, presented by the World Packaging Organisation, recognize packaging concepts that demonstrate technical innovation and practical applicability. The recognition follows the recent Green Packaging Star Award and highlights the practical progress the company is making in improving Design for Recyclability and resource efficiency while reducing the carbon footprint of packaging.
ComforLid is a patented lid concept developed as an alternative to conventional snap-on plastic lids and straws. The structure combines a polypropylene (PP) layer with an aluminum layer that can be manually separated by consumers, allowing each material to be directed into its respective recycling stream where collection and sorting systems exist.
“The award is an important acknowledgment of our relentless drive for product innovation,” said Marc Rademacher, EVP Consumer Commercial, Group R&D, and Group Sustainability at Constantia Flexibles. “Our focus with ComforLid was to improve material efficiency, lower its carbon impact, and support recyclability through design, while ensuring compatibility with existing filling and sealing equipment.”
The award is an important acknowledgment of our relentless drive for product innovation.
Material use was reduced during development through downgauging of both layers: aluminum thickness was reduced from 50 µm to 45 µm, and the PP layer from 40 g to 35 g. Combined with aluminum sourced from ASI-certified European suppliers and produced with a higher share of recycled content and renewable energy―the company’s Low Carbon Aluminum―these measures contribute to a reduction of up to 43% in the lid’s CO₂ impact compared with previous material specifications.
ComforLid is part of Constantia Flexibles’ Ecolutions product line, which groups the company’s packaging solutions designed for recycling. The lid structure aligns with RecyClass guidelines for material separability and high-quality recycling, though actual recycling performance depends on local infrastructure.
The solution can be adapted for applications such as ready-to-drink beverages and dairy products, including features like drinking openings for cold coffee or functional openings for products such as mini mozzarella.
