FUNKYPACK: FUnctional and Novel biobased solutions for KeY barriers in PACKaging

Important results from the project

Bio-based barrier solutions were developed within three chemistry platforms, PHA polymer, sol-gel and wax, for three-dimensional cellulose-based packaging. Sol-gel dispersions achieved high water resistance and also functioned as fiber binders. Wax formulations with an increased proportion of biodegradable components were developed for take-away. Standardized barrier tests, recyclability analysis and a life cycle analysis of bio-based snack lids compared to PP lids were conducted.

Expected long term effects

The project contributes to reducing the packaging industry´s dependence on fossil-based barrier chemistry. Demonstrated alternatives with competitive barrier performance support the broader transition from plastic to cellulose-based formats. A submitted patent application and ongoing proposal for continued funding indicate a credible path to commercialization. Ongoing migration testing will support regulatory approval for food contact applications.

Approach and implementation

The project was carried out by a consortium consisting of chemical developers (Bioextrax, DTI, BIM Kemi) and application expertise (Yangi), with packaging manufacturers and brand owners as strategic partners who set industrial eligibility requirements. Three chemistry platforms were developed and evaluated in parallel. Deliverables included barrier evaluation methods, recyclability analysis, life cycle analysis, food contact regulatory review and migration testing.
