Researchers at Łukasiewicz - Industrial Chemistry Institute are developing biodegradable food foils to extend the freshness of bread and reduce waste. The new material, based on chitosan, is non-toxic, biocompatible, and resistant to tearing, with added green plasticizers and natural additives that combat microorganisms. Although more expensive, the biodegradable packaging aligns with legal regulations and addresses the issue of food waste, requiring further research for optimization and market introduction. The team is seeking partnerships to fund the necessary research.
