21 Oct 2021 --- Researchers at the King Mongkut’s Institute of Technology Ladkrabang in Thailand have developed a polylactic acid (PLA) composite pineapple leaf fiber biopolymer. The composite could help meet the growing demand for biodegradable food packaging. The formulation consists of 10% PLA and pineapple leaf fiber, which exhibited enhanced melting temperatures, heat resistance and barrier properties. The antimicrobial material also inhibited the growth of various foodborne pathogens and minimized the number of foodborne pathogens on material surfaces.
