Maine’s PFAS Food Packaging Ban Takes Effect May 25, 2026: What Restaurant Suppliers Need to Do Now
Last updated: April 22, 2026 — 33 days until enforcement begins.
On May 25, 2026, Maine becomes one of the strictest states in the US for PFAS in food packaging. The ban — finalized under Chapter 80 Section 5 of Maine’s Department of Environmental Protection rules — prohibits the sale of plant-fiber food packaging with intentionally added PFAS. This isn’t about food safety testing or labeling. It’s a sales ban. If your paper-based food containers have fluorinated grease-resistance coatings, you cannot legally sell them in Maine after May 25.
This guide explains exactly what’s banned, who’s affected, and what to do about it in the next 33 days.
What Exactly Is Banned?
The ban covers food packaging “comprised, in substantial part, of paper, paperboard, or other materials originally derived from plant fibers” that contain intentionally added PFAS. Nine specific product categories are named: bags, sleeves, bowls, plates, food boats, wraps and liners, pizza boxes, containers, and related items used for direct food contact.
The key phrase is “intentionally added.” This means any fluorinated chemical applied during manufacturing to provide grease, oil, or moisture resistance. It does not cover trace PFAS from environmental contamination — only deliberate chemical treatment.
Who Is Exempt?
Companies with less than $1 billion in annual national sales are exempt from this specific provision. However, this exemption applies to the manufacturer or brand owner, not the restaurant using the packaging. If you’re a restaurant buying from a large national distributor whose supplier exceeds the $1B threshold, the packaging you receive must be compliant.
Plastic containers (PP, PET, PS) are not covered by this ban — PFAS concerns in food packaging are specific to paper and fiber products where fluorinated coatings replace natural grease barriers.
The Broader US PFAS Landscape
Maine joins a growing wave. As of April 2026, at least 12 US states actively enforce PFAS restrictions on food packaging: California (AB 1200), New York, Washington, Vermont (expanded January 2026), Connecticut (broader framework effective July 2026), Colorado, Maryland, Minnesota, Hawaii, Oregon, Rhode Island, and Illinois (effective January 2026). Nearly 100 new PFAS bills were introduced across 17 states in 2026 alone.
At the federal level, the FDA revoked 35 PFAS food contact notifications in January 2025, with full compliance required by June 30, 2025. Any remaining inventory of PFAS-coated fiber food packaging carries both regulatory and reputational risk.
Your 33-Day Compliance Checklist
Step 1: Audit your current paper-based packaging. Check every paper cup, kraft bag, pizza box, food boat, paper plate, and fiber clamshell in your supply chain. Ask your supplier directly: “Does this product contain intentionally added PFAS or fluorinated grease-resistance treatments?” Get the answer in writing.
Step 2: Request compliance documentation. A verbal “it’s PFAS-free” isn’t sufficient. Ask for a Declaration of Conformity or Certificate of Analysis that specifically states no PFAS have been intentionally added.
Step 3: Switch to verified PFAS-free alternatives. Multiple PFAS-free technologies now exist at commercial scale: water-based barrier coatings, mechanically densified greaseproof paper, PLA coatings on fiber, silicone treatments, and uncoated bagasse (naturally grease-resistant without any chemical treatment).
Step 4: Deplete existing inventory before May 25. There is no sell-through grace period. Product in warehouse after May 25 that contains intentionally added PFAS in plant-fiber food packaging cannot be sold.
PFAS-Free Alternatives That Work
| Product | PFAS-Free Solution | Price Impact |
|---|---|---|
| Pizza boxes | Uncoated high-density corrugated kraft | +5% |
| Burger wrapping paper | Mechanically densified greaseproof | +5–10% |
| Paper food boats | Silicone-treated kraft | +10–15% |
| Bakery bags | Water-based barrier coated kraft | +10% |
| Molded fiber bowls | PLA-coated bagasse | +10–20% |
| Clamshell containers | Uncoated bagasse (naturally grease-resistant) | +15–25% |
Why This Matters Beyond Maine
The direction of PFAS regulation is one-way — toward elimination. The EU’s PPWR goes further, capping total PFAS at 50 parts per million in all food packaging from August 12, 2026. Switching to PFAS-free packaging now means you won’t need to switch again as additional states and countries adopt bans.
