What Reynolds says and does about PFAS
We found no PFAS statement from Reynolds on its own site. A 2021 Mamavation lab test reported 14 ppm total fluorine in Reynolds Kitchen Parchment Paper, which Mamavation said does not show intentional addition but still could not recommend. The same outlet reported non-detect fluorine for Reynolds Non-Stick Aluminum Foil.
