Constantia Flexibles, one of the leading flexible packaging producers globally, has earned the RecyClass Letter of Compatibility (Design for Recycling) for its innovative pharmaceutical packaging, Perpetua Alta.

The 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 commitment to advancing sustainable, recyclable packaging products and represents an opportunity to reduce waste and environmental impact in the pharmaceutical industry.

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 96 percent score in the recyclability assessment by the cyclos-HTP Institute, setting a new standard in both innovation and environmental responsibility.

Dr. Joerg Adrian, vice president of technical organization and pharma innovation at Constantia Flexibles, commented: ‘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 is a range of fully recyclable mono PP laminates engineered to provide superior performance while enhancing sustainability throughout the value chain.
