PFAS-free food board uses grease- and moisture-resistant barriers that do not rely on intentionally added per- and polyfluoroalkyl substances — the class of “forever chemicals” under increasing state scrutiny in food-contact paper packaging. Takeout operators, bakery brands, and CPG teams spec PFAS-free board to stay ahead of patchwork state laws and to align marketing claims with actual chemistry. Uncoated paperboard is not grease-proof; compliant programs specify explicit barrier systems and document them in purchase orders. BoxYourBrand produces food packaging and burger boxes with PFAS-free barrier options.
This guide covers what PFAS-free means in practice, regulatory context, and specification language for your next food board order.
Key takeaways
- PFAS historically appeared in grease-resistant coatings — many states now restrict intentionally added PFAS in food-contact paper.
- PFAS-free barriers use alternative chemistries — specify product type and hold time so engineering matches performance.
- Substrate (SBS vs kraft) is separate from barrier compliance — both need explicit coating specs.
- Request supplier written confirmation of PFAS-free status for audit trails.
What is PFAS in food packaging?
PFAS (per- and polyfluoroalkyl substances) are a large class of fluorinated compounds valued for oil and water repellency. They were used in some grease-resistant paper and board coatings for fast food, bakery, and microwave popcorn applications.
Environmental and health concerns — persistence in environment, bioaccumulation — drove state-level restrictions on intentionally added PFAS in food packaging, alongside FDA phase-out of certain PFAS food-contact uses. National brands shipping across states increasingly default to PFAS-free barriers rather than maintaining separate SKU chemistries by region.

PFAS-free vs uncoated board
| Term | Meaning |
|---|---|
| Uncoated kraft/SBS | No barrier — not grease-proof |
| Legacy grease-resistant | May have used PFAS chemistry — verify before reorder |
| PFAS-free grease barrier | Alternative chemistry — specify for fried/baked foods |
| PLA or bio-based liners | Separate compostability story — not automatic PFAS-free |
PFAS-free does not mean “no coating.” Greasy burgers, pastries, and sauced takeout still need food-grade grease barriers — just without intentionally added PFAS where restricted.

State rules (overview)
State laws evolve — confirm current statutes before national rollouts. Common pattern: ban on intentionally added PFAS in food-contact paper or paperboard after specified effective dates, with exemptions sometimes phasing out.
Operators with multi-state delivery should:
- Spec PFAS-free barriers in master PO language
- Avoid “grease-resistant” without chemistry documentation
- Align public eco claims with actual barrier certificates

Specifying PFAS-free on purchase orders
Include in quote and PO:
- Product contact surface — direct vs indirect (liner vs outer wrap).
- Food type — fried, baked, frozen, sauced — hold time and temperature.
- “PFAS-free grease barrier” — explicit language, not generic “food safe.”
- Written supplier confirmation — for retailer and audit requests.
Request food packaging quote with PFAS-free requirement noted. Order samples to validate barrier performance with your actual menu items before MOQ.
Performance and testing
PFAS-free alternatives perform for typical QSR and bakery hold times when matched to product. Extreme cases — long hot-hold fried chicken, heavy oil pooling — may need:
- Venting (see burger box packaging guide)
- Separate grease liners
- Heavier board caliper
Test with production menu items, not water alone, before locking annual packaging contracts.
