en.Wedoany.com Reported - The VTT Technical Research Centre of Finland and LUT University have jointly developed a new cellulose-based material platform aimed at helping packaging manufacturers reduce their reliance on fossil-based plastics while meeting the performance standards required for industrial applications. This technology advances all-cellulose films and coatings that can be processed using existing manufacturing methods and are capable of scalable commercial production.
This development is part of the "Films for Future" (F3) project, which focuses on creating bio-based packaging materials with plastic-like functionality and supporting improved end-of-life disposal options. Researchers report that the cellulose material can be formed into transparent films with mechanical strength and barrier properties comparable to conventional plastic films.
By processing cellulose as a polymer rather than traditional fibers, the researchers have produced films and coatings with enhanced performance characteristics. The resulting materials are suitable for applications requiring barrier protection, transparency, and compatibility with existing packaging processes.
The platform includes free-standing cellulose films and cellulose-based coatings for fiber-based packaging systems. According to the researchers, the films offer oxygen barrier properties comparable to conventional plastics, while the coatings provide oxygen and grease resistance for recyclable paper and cardboard packaging applications.
The F3 project has demonstrated pilot-scale production capabilities across various applications, including dry food packaging, bakery products, and fiber-based packaging requiring transparent barrier layers.
The researchers state that the technology is designed for integration with current industrial processing techniques, including thermoforming, which helps simplify the adoption process for manufacturers. The next phase will focus on scaling the technology for commercial applications and improving its performance under high-humidity conditions.
Beyond replacing plastic packaging, the material platform can also support future functional coatings, including antimicrobial, antioxidant, and responsive packaging systems that can react to environmental conditions such as humidity, gas composition, or pH.
The project involves VTT, LUT University, and industry partners, and has received funding from the European Regional Development Fund. Researchers indicate that continued development will focus on advancing the material from pilot-scale demonstrations toward broader industrial applications.
