Films for Future (F3) project is a collaboration between research (VTT, LUT) and industrial partners established to explore the possibilities of cellulose-based films and coatings as barrier materials and packaging applications. Application development effort and pilot equipment for technology demonstration at VTT Bioruukki piloting center in Espoo, Finland was set up. The pilot facility is used to provide facilities for proof-of-concept purposes to produce stand alone films and coating of carton boards using regenerated cellulose dissolved using different chemistries.

Reduction of fossil based raw material usage together with environment concerns are main drivers for research to find alternatives for plastics in packaging applications. Also legislative efforts have been set up to limit certain single-use plastics. Transparent cellulose films and cellulose based coatings are an example of novel technology with potential to impact global packaging market as alternative for polypropylene based being bio-based and bio-degradable. Films for Future (F3) project is a collaboration between research (VTT, LUT) and industrial partners established to explore the possibilities of such cellulose-based films and coatings. (4) VTT has been working on cellulose dissolving chemistries and regenerating of cellulose for over a decade with earlier focus on filament manufacturing. Recently research has been more and more dominantly been concentrating on packaging solutions with special focus on barrier development. Transparent regenerated cellulose based coatings and films based on laboratory experiments provide excellent barrier against both oxygen and water vapour in addition being grease proof. Films are strong, tough and superior in stretchability compared to carton board. (4) Encouraged by laboratory scale experiments a major material and application development effort and pilot equipment for technology demonstration at VTT Bioruukki piloting center in Espoo, Finland was set up. The pilot facility is used to provide facilities for proof-of-concept purposes to produce stand alone films and coating of carton boards using regenerated cellulose. (2)
