Historical research supports some grease-resistant packaging as a PFAS exposure source. The US market changed: FDA says the relevant materials covered by a voluntary phaseout stopped being sold for US food packaging in February 2024.[1] [2]
Why older packaging used PFAS
Fluorinated treatments were used to resist grease. That history does not establish what is in a package sold today.[2]
Historical biomonitoring cannot describe the current market
NHANES 2003-2014 found higher selected serum PFAS among frequent popcorn consumers. Dietary recall, cross-sectional data and other food differences prevent proof that packaging supplied the exposure.[1]
Do not assume current migration
The supplied corpus does not verify current US package-specific migration after the phaseout. Heat and grease claims from older products should not be presented as universal current facts.
A nationwide phaseout matters more than old chain lists
FDA's February 2024 announcement covers grease-proofing PFAS materials subject to the voluntary market phaseout. It does not prove that every possible PFAS is absent from every package.[2]
Keep the advice practical
Use reusable dishes when convenient, reduce unnecessary disposable packaging and check current manufacturer information. Do not treat every wrapper as contaminated.

Supports: Historical NHANES data associated frequent popcorn consumption with higher serum levels of selected PFAS. The study could not isolate packaging and predates the 2024 US phaseout.
Evidence class: Human cross-sectional exposure study

Supports: FDA announced on February 28, 2024 that grease-proofing PFAS materials covered by the voluntary phaseout were no longer being sold for US food packaging.
