PaperFlex Consortium Accelerates Paper-Based Flexible Packaging Innovation

Paper-based flexible packaging is attracting growing attention as the packaging industry looks for alternatives to conventional plastic structures. On September 16, 2026, the Ellen MacArthur Foundation announced the launch of the PaperFlex Consortium, bringing together six global consumer goods companies to accelerate the development and application of paper-based flexible packaging solutions.

The founding members of the consortium are Colgate-Palmolive, Mars, Nestlé, PepsiCo, Procter & Gamble, and Unilever. The initiative focuses on small-format flexible packaging, including wrappers, pouches, and sachets, which are widely used for food and consumer products but can be difficult to collect and recycle in some markets because of their small size and complex material structures.

The consortium aims to promote collaborative research and testing rather than having individual companies develop solutions separately. By bringing major consumer brands together, PaperFlex will explore technologies that could help make paper-based flexible packaging more suitable for real-world applications.

Replacing plastic with paper is not simply a matter of changing the primary material. Flexible packaging needs to protect products during transportation, storage, and use while also running reliably on high-speed packaging lines. Depending on the application, packaging materials may also require resistance to moisture, grease, oxygen, or other external factors. These requirements can be difficult to achieve with conventional paper alone.

Coating technologies and material structures will therefore play an important role in the development of paper-based flexible packaging. The PaperFlex Consortium will explore areas including biodegradable coatings, new coating technologies, and improvements that can help paper-based materials perform more effectively on existing production equipment. These developments are intended to address some of the technical, economic, and scalability challenges facing paper-based alternatives.

The initiative also reflects the packaging industry's growing focus on recyclability and end-of-life performance. Research from the Ellen MacArthur Foundation has highlighted the need to consider factors including responsible sourcing and production, packaging performance, local recycling conditions, and the avoidance of hazardous chemicals and persistent plastic pollution when developing paper-based flexible packaging.

This means that future paper-based packaging will need to meet more than a basic requirement for higher paper content. Product protection, coating compatibility, recyclability, production performance, and end-of-life treatment can all affect whether a paper-based structure is suitable for a particular application.

For paper suppliers and packaging manufacturers, the launch of the PaperFlex Consortium is another signal that paper applications may continue to expand beyond traditional printing and packaging uses. As major consumer goods companies work together on paper-based flexible packaging, new requirements may emerge for papers that can support specific coating, printing, converting, and food-packaging processes.

However, large-scale adoption will still require further progress in performance, cost, and manufacturing efficiency. The launch of PaperFlex represents a new stage of collaboration rather than the end of the development process. As consumer brands, paper suppliers, coating technology companies, converters, and recycling systems work more closely together, paper-based flexible packaging is likely to remain an important area of innovation in the global packaging industry.
