PFAS-Free Food Packaging: What the 2026 State Bans Actually Require

Twelve U.S. states now restrict intentionally added PFAS in food packaging, and as of 2026 the question is no longer whether to switch — it's whether your "PFAS-free" supplier can actually prove it. The bar most states use is blunt: fiber-based packaging has to test below 100 parts per million of total fluorine. Miss that number and your product is illegal to sell in those markets, no matter what the sales sheet promises. That's the catch most brands discover too late.

Editor's note: PFAS-free is not a marketing claim. It's a lab result — and most brands have never asked to see the lab.

What exactly did the states ban?

As of 2026, twelve states have laws on the books restricting intentionally added PFAS in food packaging or foodservice ware: California, Colorado, Connecticut, Hawaii, Maine, Maryland, Minnesota, New York, Oregon, Rhode Island, Vermont, and Washington. New York and California started the clock back in 2022 and 2023; Oregon and Rhode Island switched on January 1, 2025; and Maine's plant-fiber category ban lands May 25, 2026, with manufacturer PFAS notifications to the state already due as of January 1, 2026, per the Safer States tracker. The map keeps growing.

The phrase doing the heavy lifting is "intentionally added." These laws don't just target the obvious grease-proofing coatings on a burger wrapper. They cover PFAS deliberately used anywhere in the package — including processing aids you may not even know your fiber mill applied. Look, that's the part that trips up sourcing teams: you can buy an uncoated kraft tray and still fail, because the contamination rode in upstream.

Why isn't the FDA phase-out enough?

Here's where a lot of brands get a false sense of safety. In February 2024 the FDA announced that grease-proofing substances containing certain PFAS were no longer being sold for food-contact use in the U.S., and in January 2025 it formally determined that 35 related food-contact notifications were no longer effective. Good news. But it was a voluntary market phase-out of new sales, not a ban on what's already in warehouses, on imported stock, or in the legacy inventory still moving through distributors.

So the federal action closed the front door while the state laws are the ones actually inspecting the building. A contrarian read most compliance decks won't give you: the FDA news arguably made things riskier, because brands read the headline, assumed the problem was solved, and stopped asking suppliers for test data. It wasn't solved. It moved.

How do you prove a package is actually PFAS-free?

You test it. The screening method regulators and standards bodies converge on is total organic fluorine, used as a proxy for the thousands of individual PFAS compounds nobody can affordably test one by one. The Toxics in Packaging Clearinghouse and state guidance both treat results at or below 100 ppm total fluorine as the practical line for "no intentionally added PFAS" in fiber. The Environmental Defense Fund makes the same recommendation: screen with total fluorine and investigate anything over 100 ppm, because that level almost always signals deliberate use rather than trace background.

Now the original data point, from our side of the table. Some had a certificate from 2021 for a different SKU. A few had nothing. In my experience that ratio holds across categories. Call it the PFAS paper gap: the distance between a supplier saying "PFAS-free" and a supplier handing you a dated lab report that proves it for the exact item you're buying.

Close that gap with three asks. Demand a recent total-fluorine certificate from a recognized lab — Intertek, SGS, or equivalent — tied to the specific product code, not the product line. Require it be re-tested annually, because mills change feedstock. And fold the PFAS test into the same supplier review where you already check other hidden costs; our guide to auditing a packaging supply chain covers how to build that scorecard so this isn't a separate fire drill every renewal.

What should you switch to?

Fiber, mostly. State regulators flagged safer alternatives before they wrote the bans, and uncoated or PFAS-free-coated molded fiber is the format that most cleanly clears the 100-ppm line for greasy, wet, hot foods — the exact applications PFAS used to handle.

• Molded fiber and bagasse. Sugarcane-pulp clamshells and trays handle oil and heat without fluorochemistry. They compost where facilities exist, and they're the default replacement for foam and coated paperboard.
• Aqueous and bio-based barrier coatings. Water-based dispersions and PLA-style linings give grease resistance without intentionally added PFAS — but confirm the coating itself was tested, not just the substrate.
• Clay or mineral-coated paperboard. For dry and semi-greasy goods, mineral barriers cover a surprising range at commodity prices.

Bagasse is the workhorse here, and it deserves its own deep dive — we wrote one on sugarcane-waste packaging for foodservice. Just don't conflate "compostable" with "PFAS-free"; they're different tests answering different questions, which is exactly the confusion our biodegradable vs compostable vs recyclable breakdown exists to untangle. If you're sourcing custom food packaging at volume and want the PFAS test built into the spec from day one, a partner like Pakingduck's custom packaging team can hold the compliance line across a full SKU set instead of one tray at a time.

That said, switching material isn't the finish line. The finish line is documentation you can produce on demand when a state regulator, a retailer, or a plaintiff's lawyer asks. Numbers don't lie. Get the test, tie it to the SKU, re-run it yearly — and treat any supplier who can't hand you a current report below 100 ppm as a liability you haven't priced yet. The bans are here. The proof is on you.
