Scientists test polylactic acid (PLA) plastic advertised as biodegradable along with standard polypropylene (PP), and polyethylene terephthalate (PET) plastics for degradation in real marine environment; no signs of degradation found after 428 days; researchers say biodegradable might be misleading term
PFAS alternatives for paper food packaging
Article in Comprehensive Reviews in Food Science and Food Safety discusses alternatives for per- and polyfluoroalkyl substances (PFAS) in paper food packaging; considers lamination with waxes and polymer films, alternative surface sizing and coatings; views finding cost-effective, fully biodegradable, and environmentally friendly alternatives challenging
New form of PLA seen as beneficial for application in hot food packaging
Researchers develop a more thermally resistant form of polylactic acid (PLA) plastic; provides clear, tough, and heat resistant material with the potential to expand PLA market application and reduce price
