PFAS-Free Packaging FAQ: What B2B Buyers Must Verify

What is PFAS and why is it in packaging?

PFAS (per- and polyfluoroalkyl substances) are synthetic chemicals used for oil and water resistance in food packaging. They earned the nickname "forever chemicals" because they don't break down and accumulate in humans and the environment, linked to immune and liver effects.

Is PFAS banned in food packaging?

Rapidly, yes. The U.S. FDA secured voluntary phase-outs, several U.S. states have enacted bans with 2024-2026 deadlines, and the EU is restricting PFAS under REACH. France already bans PFAS in food packaging. Buyers should treat PFAS-free as a baseline requirement, not a differentiator.

How do I verify a supplier's PFAS-free claim?

Request a third-party test report measuring total organic fluorine below 100 ppm (the industry benchmark) from an ISO 17025 accredited lab. Ask for total fluorine, not just specific PFAS compounds, because suppliers sometimes test only a narrow list. Re-verify annually.

Is molded pulp packaging PFAS-free?

Certified molded pulp is PFAS-free by design: it uses mechanical pulp and, where a barrier is needed, water-based or plant-wax coatings instead of fluorinated chemicals. BPI now requires PFAS-free status for compostable certification, so BPI-certified molded pulp is verifiably PFAS-free.

What are the alternatives to PFAS for grease resistance?

Alternatives include water-based barrier coatings, PLA bioplastic linings, and plant-wax treatments. For molded pulp, the fiber structure itself plus a water-based coating handles most food-service needs. Confirm the specific barrier technology and its test data with your supplier.
