Important results from the project
The project has successfully demonstrated the potential of thermoplastic starch (TPS) films for advanced packaging applications by significantly enhancing their mechanical and barrier properties, as well as optimizing production. The laminated films exhibit excellent water and oil barriers, are 3D-formable, and have been optimized for multilayer structures. Despite challenges with barrier compatibility, new partnerships were formed and several promising solutions were identified for next step.
Expected long term effects
The project demonstrates that the starch films can be produced on an industrial scale through efficient one-step extrusion, resulting in lower costs, reduced energy consumption and higher efficiency. Optimized process parameters improved strength, stability, and barrier performance. The laminated films exhibit excellent water and oil barriers, are suitable for multilayer packaging, and show scalability without quality loss, supporting commercialization as an alternative to fossilbased packaging.
Approach and implementation
The project has largely followed the planned structure, although the timeline has been somewhat extended. Most activities have been carried out in parallel and with some overlap to enable effective coordination with the participating partners´ operations. The collaboration between the parties has worked well, with all partners demonstrating great flexibility and commitment in adapting and optimizing activities in response to insights and challenges encountered throughout the project.
