A new bio-based material platform developed in Finland is making significant progress in replacing fossil-based plastics in packaging. The project, led by VTT Technical Research Centre of Finland and LUT University, focuses on fully cellulose-based films and coatings. It responds to tightening regulations and industry demands to reduce plastic use and improve recyclability.
The technology transforms cellulose into a polymer, creating transparent films with plastic-like strength and barrier properties. These films are inherently biodegradable and compatible with existing recycling systems. Coatings are designed to be recyclable within fiber-based packaging or biodegradable when needed.
This innovation comes as regulations such as the EU Packaging and Packaging Waste Regulation (PPWR) require more recyclable and sustainable materials. The new cellulose films and coatings meet these requirements without sacrificing performance.
“Plastic films are widely used but difficult to recycle and major environmental pollutants,” said Ali Harlin, Research Professor at VTT. “Our cellulose materials offer a sustainable solution that helps manufacturers meet new regulations while maintaining product quality.”
The platform is compatible with current converting technologies, supporting industrial scalability. It offers high transparency, strength, and barrier properties similar to plastics, and can be processed with conventional methods like thermoforming.
LUT University’s Professor Ville Leminen highlighted the potential: “Our films and coatings have demonstrated processing in various packaging methods, showing promising future applications.”
Additionally, the technology can support active packaging features, such as antimicrobial or humidity-responsive functions, suitable for future smart packaging. Beyond packaging, the materials could find uses in medical devices, electronics, and functional coatings.
Industry leaders emphasize that scalability and compatibility with existing systems are key for commercial adoption. The next phase aims to scale up production and develop new multifunctional applications.
