fluorinated polyethylene

Environmental groups have strengthened calls for thorough regulatory review of per- and polyfluoroalkyl substances (PFASs) in food contact materials (FCMs) after discovering that the US FDA cleared several PFASs for plastic food packaging manufacture in the past decade.

The NGOs’ findings – reached through a Freedom of Information Act (Foia) request – follow the detection of PFAS contamination in fluorinated polyethylene containers, which prompted EPA and FDA investigations and the latter’s warning against unauthorised fluorination.
