A wood fibre only 100 nanometres thick will help to give us tomorrow’s plastic food packaging, if SINTEF and its partners are successful. Most of today’s plastics are petroleum-based, but now scientists are trying to create a climate-friendly alternative to plastics. The background of the project is that the European Union has the ambition to make Europeans healthier by offering them more fish and seafood. Packaging that prolongs the shelf life of food can help to persuade more consumers to choose healthier alternatives and at the same time, reduce food waste. In the Nano-Barrier project, 15 participants are testing renewable resources as bioplastic and microfibrillated cellulose.
