Imagine your favourite croissant comes in plastic wrap that takes centuries to decompose. This project swapped that petroleum-based plastic for a plant-made alternative called PHA — think of it as nature's own cling film. The problem was that PHA lets too much moisture and air through, making baked goods go stale faster. So the team layered it with another bio-plastic and added ultra-thin mineral coatings to lock freshness in, proving it can keep bakery products crisp at least 10% longer than before.
Food manufacturers — especially bakeries — face mounting regulatory and consumer pressure to eliminate petroleum-based plastic packaging, but current biodegradable alternatives let too much moisture and oxygen through, causing products to go stale or oxidize faster. Companies need a compostable packaging film that actually performs as well as conventional plastic, or they risk either environmental backlash for staying with plastic or product quality complaints for switching too early.
The project developed enhanced PHA-based biodegradable food packaging films using two approaches: multi-layer PHA/PLA laminates and surface-treated PHA films with nano-metallization coatings (AlOx, SiOx, or aluminium). These were validated on real bakery products, and a report on exploitation pathways for commercialization was produced.
If you are a bakery manufacturer dealing with products going stale on shelves and facing growing pressure to eliminate petroleum-based packaging — this project developed PHA-based biodegradable films with enhanced moisture and oxygen barriers that extend shelf-life by at least 10%. The materials were validated specifically on bakery products with different shelf-life requirements.
If you are a packaging converter looking for the next generation of compostable film materials — this project developed multi-layer PHA/PLA laminates and surface-treated PHA films using metallization with AlOx or SiOx coatings. These are drop-in solutions designed to fit existing extrusion and converting lines, opening a new bio-based product line for your catalogue.
If you are a bioplastics producer struggling with limited market uptake of PHA due to its medium barrier performance — this project proved that PHA can be functionalized through lamination and surface treatment to compete with conventional food packaging polymers. The validated results on real bakery products give you concrete data to pitch PHA to food industry buyers.
The project data does not include specific cost comparisons or pricing for the developed materials. However, the consortium included bioplastic producers, extrusion actors, and converters along the full value chain, suggesting the economics were considered. You would need to contact the consortium for current material pricing.
The project was a Research and Innovation Action (BBI-RIA) that validated materials on real bakery products. With 4 industrial partners and 5 SMEs in the consortium — including film producers and food companies — the project was designed with scale-up in mind. Based on available project data, a report on future exploitation actions was produced, indicating pathways toward commercialization.
The project produced deliverables including a report on contextualisation for future exploitation actions, which likely covers IP and licensing routes. The consortium includes both research institutions and industrial partners across 4 countries (DK, ES, FI, IT). Contact the coordinator TECNOALIMENTI SCPA in Italy to discuss licensing options.
The project specifically aimed to validate materials in the food industry environment on bakery products, which implies food-contact compliance was part of the validation process. Based on available project data, the materials were tested on real food products with different shelf-life requirements. Specific regulatory certifications should be confirmed with the consortium.
The project objective explicitly states a target of increasing shelf-life by at least 10%. This was validated on bakery products representative of different shelf-life requirements and duration, including products where moisture uptake and fat oxidation are the critical factors.
The project developed two approaches: multi-layer PHA/PLA laminates and surface-treated PHA films using standard metallization processes (AlOx, SiOx, or aluminium). These are established industrial processes, suggesting compatibility with existing converting equipment. Based on available project data, the consortium included extrusion, filming, and converting actors to ensure industrial feasibility.
The BioBarr consortium of 8 partners across 4 countries (Denmark, Spain, Finland, Italy) is well-structured for bringing packaging innovation to market. With a 50% industry ratio and 5 SMEs, this is not a purely academic exercise — half the team are companies that need to sell products. The consortium covers the entire bio-based packaging value chain from bioplastic production through extrusion and film converting to food industry end-users, coordinated by Italian food technology SME TECNOALIMENTI. The presence of 2 universities and 2 research organizations provides the scientific backbone, while the industrial partners ensure the results are grounded in manufacturing reality.
TECNOALIMENTI SCPA is an Italian food technology SME. Use Google to find the project coordinator's contact details — search for the BioBarr project coordinator name and email.
