Per- and Polyfluoroalkyl Substances in Food Packaging: Second Alternatives Assessment

Download the document.

This is the second Washington State Department of Ecology (Ecology) alternatives assessment
(AA) of per-and polyfluoroalkyl substances (PFAS) in plant-fiber-based food packaging. This AA
is pursuant to the requirements of RCW 70A.222.070, which restricts the manufacture,
distribution, and sale in Washington of “food packaging to which PFAS chemicals have been
intentionally added in any amount.” PFAS are intentionally added to some paper food
packaging products to provide oil and grease resistance, water repellency, and leak resistance.
The restriction timeline depends on when we identify safer alternatives to PFAS in food

This AA: evaluates less toxic chemicals and nonchemical alternatives to replace the use of PFAS in food packaging; follows the guidelines for alternatives assessments issued by the Interstate Chemicals Clearinghouse (IC2); includes, at a minimum, an evaluation of chemical hazards, exposure, performance, cost, and availability.
