The main purpose of this legislation is to protect public health by banning the use of certain harmful chemicals in food packaging. Specifically, it aims to prohibit the introduction or delivery of food packaging that contains intentionally added per- and polyfluoroalkyl substances (PFAS) into interstate commerce. PFAS are a group of chemicals often used for their water- and grease-resistant properties, but they have been linked to various health risks. Key provisions of the law include the explicit ban on food packaging with intentionally added PFAS.
