As the EU's Packaging and Packaging Waste Regulation (PPWR) nears implementation, the demand for mono-material packaging solutions has never been more critical. In response, Constantia Flexibles proudly announces that one of its innovative pharmaceutical packaging solutions, PERPETUA ALTA, has earned the RecyClass Letter of Compatibility (Design for Recycling).

This certification is based on PERPETUA ALTA's status as the first high-barrier polypropylene (PP) mono-material laminate to receive RecyClass Technology Approval. It highlights the company's continued commitment to advancing more sustainable, recyclable packaging solutions and represents a welcomed opportunity to reduce waste and environmental impact in the pharmaceutical industry.
A milestone in high-barrier, recyclable pharmaceutical packaging
The certification was earned after a thorough assessment under the 2024 guidelines, confirming its recyclability and compatibility with European recycling streams for flexible PP packaging. In addition, PERPETUA ALTA has achieved a remarkable 96% score in the recyclability assessment by the cyclos-HTP Institute, setting a new standard in both innovation and environmental responsibility.
Dr. Joerg Adrian, VP of Technical Organization & Innovation Pharma at Constantia Flexibles, emphasized, "Our PERPETUA family solutions mark a revolutionary step forward in fully recyclable packaging, aligning with the upcoming PPWR requirements and scope 3 reduction targets for the pharmaceutical industry. By leveraging a holistic, system-thinking approach, we have developed a mono-material solution that ensures the high performance necessary to maintain the quality and protection of medicines while also delivering environmental benefits at every stage of the life cycle.”
PERPETUA family: Innovative design and performance
PERPETUA is an innovative range of fully recyclable mono PP laminates engineered to provide superior performance while enhancing sustainability throughout the value chain. These high-barrier laminates are compatible with existing packaging lines that use non-recyclable materials, ensuring a seamless transition. They offer exceptional protection against oxygen, water vapor, and light, preserving product quality. With a significantly reduced environmental footprint, it outperforms traditional PET-ALU-PE solutions, offering up to a 55% reduction in carbon emissions* and using on average 12% less material without sacrificing functionality.
