PFAS in packaging: what brands need to know

Requirements and timelines change. This page was last verified against U.S. FDA and EPA guidance and the state PFAS programs where products are sold on 18 July 2026. Always confirm the current version with the FDA, the EPA, and your state's program before you rely on it. This is general guidance, not legal or compliance advice.

What PFAS actually are

PFAS stands for per- and polyfluoroalkyl substances — a large family of synthetic chemicals built around very strong carbon-fluorine bonds. That same bond strength is what makes them useful and what makes them a problem: it's why they shrug off grease, oil, and water, and also why they break down extremely slowly in the environment and in living things. That persistence is the reason they picked up the nickname "forever chemicals."

PFAS isn't one substance; it's thousands of related compounds with widely varying properties. Regulators and researchers have raised health and environmental concerns about several of the more studied members of the family, which is what's driving the current wave of restrictions on their use in consumer products — including food-contact packaging. We're describing the general trajectory here, not making any health claim: for the science and the specific substances of concern, the FDA and EPA are the authorities to consult.

Why PFAS ended up in packaging

The appeal in packaging was simple: PFAS treatments give paper and molded fiber a grease and moisture barrier without laminating on a layer of plastic. A fiber bowl that would normally go soggy under a hot, oily meal could instead be treated to hold up — cheaply, at high speed, and while still looking and feeling like paper.

That's why PFAS historically turned up in exactly the products you'd expect: fast-food wrappers and clamshells, bakery and deli bags, microwave-popcorn bags, molded-fiber bowls and takeout containers, and some pet-food and pre-formed food packaging. There's an uncomfortable irony baked in: some fiber packaging marketed as compostable or recyclable carried PFAS treatments, which undercut those very end-of-life claims. PFAS sits inside the broader landscape of food packaging regulations, and it's one of the fastest-moving corners of it.

Where PFAS hide in packaging

You generally can't see or feel PFAS. They're applied as surface treatments, internal sizing, or coatings, so a treated fiber component looks like ordinary paper. That's what makes documentation — rather than eyeballing — the only reliable way to know. The components worth scrutinizing first are the ones that need a grease or water barrier while staying fiber-based.

Packaging component	Why PFAS was used	What to check
Grease-resistant paper	Repels oil in wrappers, liners, and bakery/deli bags	Ask for a no-intentionally-added-PFAS attestation on the paper grade
Molded fiber	Bowls, clamshells, and trays that must resist hot, oily food	Confirm the barrier chemistry; PFAS-free molded fiber is widely available
Microwave-popcorn bags	Grease barrier under heat	Historically a high-risk item; verify the current material spec
Coatings & sizing agents	Water and oil repellency added during papermaking	Request the coating's compliance documentation, not just the base stock's
Inks & adhesives	Less common, but fluorinated additives can appear	Include them in supplier attestations to close the gap

One clarifying point about barriers: PFAS is only ever one way to keep grease and moisture out. A multi-layer film or a paper-plus-film construction — a laminate structure — achieves a barrier physically rather than chemically, which is why format choice and PFAS status are intertwined.

Laminate structure — a packaging material built from two or more bonded layers (for example paper laminated to a film, or several films together) engineered to deliver barrier, strength, and sealability that no single layer provides. See more terms in the packaging glossary.

The regulatory direction

There is no single national on/off switch that neatly bans every PFAS use in every package. But the direction of travel is unambiguous, and it's toward restriction. Two forces matter for a packaging buyer.

Federal action. The FDA has moved on PFAS used as grease-proofing agents in food-contact paper and board — the trend is that these substances are being phased out of the US food-packaging supply. Separately, the EPA has advanced PFAS oversight under the Toxic Substances Control Act, including reporting obligations that can reach manufacturers and importers. We're deliberately not quoting specific effective dates or thresholds here, because they change: confirm the current status directly with the FDA and the EPA.

State laws. A growing number of US states have enacted laws restricting intentionally added PFAS in food packaging, and some reach beyond food to broader packaging categories. The catch is that the covered materials, the definitions, the screening thresholds (often expressed as total organic fluorine), and the effective dates differ from state to state and continue to evolve. Treat "which states, which rules, by when" as something you verify per state program you sell into — not as a fixed list you can memorize once.

Two concepts recur across these rules and are worth knowing. "Intentionally added" PFAS generally means PFAS put there on purpose to serve a function (like grease resistance), as distinct from trace contamination. And total organic fluorine is commonly used as a screening proxy — if a material carries fluorine above a program's threshold, it flags for a closer look. PFAS is one thread in a much larger fabric; for the rest, see our guide to US packaging compliance.

How to get to PFAS compliance

The good news for most brands: you don't need to become a chemist. The practical middle path is a documentation and verification loop you run with your suppliers. It looks like this.

1. Map your packaging. Inventory every component and flag the fiber-based, grease-or-water-resistant ones first — those are where PFAS is most likely to hide. Rigid plastics and glass are lower on the list; treated paper and molded fiber are higher.
2. Request an attestation from every supplier. Ask for a written certificate of compliance stating there are no intentionally added PFAS, and that the material meets the requirements for the markets you sell into. Get it for the finished component, not just the base stock, so coatings and treatments are covered.
3. Verify when the stakes are high. An attestation is a claim, not proof. For high-risk items or new suppliers, request laboratory test data (often reported as total organic fluorine) or commission independent testing. Verifying the people who make your packaging is part of the same diligence covered in how to evaluate a contract packer.
4. Document everything, per SKU. Keep attestations, specification sheets, and any test reports in a file tied to each product. If a regulator, retailer, or customer asks, you want to produce the record in minutes, not scramble for it.
5. Re-check on every change. A new supplier, a substituted material, or a rule update all reset the question. Build a habit of re-confirming rather than assuming last year's attestation still holds.

PFAS-free alternatives

Restriction doesn't mean you lose the barrier — it means you get it another way. The grease and moisture resistance PFAS provided can usually be achieved with alternatives, each with its own trade-offs in performance, recyclability, and cost. The right pick depends on the product, the barrier you actually need, and your end-of-life goals.

• PFAS-free paper treatments — newer fluorine-free grease-resistance chemistries designed as drop-in replacements for many applications.
• Mineral and clay coatings — non-fluorinated coatings that build a barrier physically.
• Better-formed molded fiber — denser forming and PFAS-free barrier systems that hold up to oil and heat.
• Plastic or laminate structures — where a film or laminate delivers the barrier and a recyclable design still works; weigh this against your recyclability goals.
• Right-sizing the barrier — sometimes the product simply doesn't need the barrier level the old spec assumed, and a lighter construction passes real fill-and-shelf-life testing.

Because barrier and recyclability pull against each other, PFAS decisions overlap with your wider sustainability strategy — see our sustainable packaging guide. And if you plan to make a recyclable or compostable claim on-pack, make sure it's truthful and substantiated; our guide to recycling labels covers how those claims are governed. Whatever you choose, validate it against your actual product and conditions before you commit — a barrier that works in a brochure isn't the same as one that survives your fill.

How PackOS helps with PFAS documentation

PFAS compliance lives or dies on documentation, and documentation lives on a clean spec. PackOS captures the material and construction spec for every package it quotes — the substrate, the layers, the finish — which is the same information a PFAS attestation attaches to. When your packaging is described precisely and consistently, it's far easier to ask the right supplier the right question, to file the attestation against the right SKU, and to re-verify when a material changes. You can see how the platform reads and structures a material spec on the technology page.
