Films and coatings for circular packaging

Expected Outcome: Successful proposals will contribute to the Circular Economy Action Plan, the Chemicals Strategy for Sustainability and the Ecodesign for Sustainable Products Regulation. Projects results are expected to contribute to the following expected outcomes: Wider availability of bio-based films and coatings for packaging products. Improved technical performances of packaging products compared to fossil based and/or bio-based benchmarks. Improved circularity of packaging products against specified market benchmarks taking into account production, use and EoL. Scope: Many research projects have focused on developing and piloting bio-based coatings and films for application in food and non-food packaging. When targeting packaging, a primary challenge is achieving adequate barrier properties (against oxygen, moisture, grease and volatiles), as bio-based materials are typically more hydrophilic than conventional plastics like PE or PET. Processing methods, including bio-based coating deposition, face scalability and reproducibility issues. Coatings must adhere well to substrates while maintaining technical properties and not hindering sustainable EoL. Printability is another concern, as bio-based surfaces can cause ink issues like smudging or poor adhesion. Durability under stress and operating conditions is still a challenge for certain bio-based applications. Finally, design for sustainability and sustainable EoL are critical to reduce over-packaging, avoid littering…
