Researchers in Finland and Spain have developed a bio-based packaging solution for cold-chain food transport amid consumer demand for sustainable and functional food packaging that offers thermal regulation and antibacterial protection. The bio-based foams were created by combining polyethylene glycol (PEG) with a cellulose structure and pomegranate peel (PMP) powder. After testing, the product achieved stable thermal regulation and integrated antibacterial and antioxidants for enhanced product safety. Moreover, a LCA determined that the bio-based foam reduced carbon footprint by 25% compared to conventional petroleum-based alternatives.
