White Corrugated Cardboard Pizza Boxes 18x18 inch Clay Coated Lock Corner
Lower-concern option; Eco-Products' PFAS-free claim backed by third-party certification.
Eco-Products explicitly markets these pizza boxes as PFAS-free and carries MADE SAFE certification, which independently vets products for harmful chemicals including PFAS. While clay coating in food packaging can historically use fluorinated grease-barriers, Eco-Products has publicly committed to non-PFAS water/grease resistance.
Brand says: “Eco-Products pizza boxes are manufactured without PFAS-containing coatings and meet FDA food-contact standards.”

Why this grade

Category baseline
food packaging is a category where PFAS exposure is more common.
Third-party PFAS-free verification
Independently verified PFAS-free by a third party.
The full breakdown
What it's made of and why it matters
This product is corrugated cardboard with a clay coating on the interior food-contact surface. Clay coatings serve as grease barriers and are chemically inert, unlike fluorinated polymer coatings (which introduce PFAS). The corrugated structure itself (kraft pulp) is standard and has no established chemical hazard profile for short-term food contact. The lock corner design is a mechanical closure and poses no chemical safety issue.
The brand's record and disclosure
Eco-Products is a subsidiary of Footprint and markets sustainability-focused food service packaging. The brand's PFAS-free claim for this product line is backed by third-party certification (specifically validated against per- and polyfluoroalkyl substance standards). The company has a documented transparency record on materials disclosure and has not faced established recalls or safety controversies for cardboard food packaging. Their messaging emphasizes fluorine-free coatings as a core differentiator.
How it compares in its category
Most pizza boxes historically used aqueous fluorochemical repellent coatings (AFFF-derived formulations containing PFOA-related compounds) or wax layers. Clay-coated alternatives like this one represent a shift toward non-fluorinated barriers, reducing the primary chemical hazard in this category. Uncoated kraft cardboard lacks grease resistance and allows oil migration; clay coating avoids both that problem and PFAS exposure. This product sits at the safer end of the spectrum for routine pizza delivery use.
If you buy it
Use for room-temperature and warm food storage only (pizza, bakery items); do not expose to direct flame or prolonged high heat above 180F, which can degrade the coating. The box is single-use and not intended for reheating food inside the packaging; transfer contents to oven-safe dishware. Replace immediately if the clay coating shows visible cracks, tears, or grease saturation (indicates barrier failure). Store flat and dry to prevent mold growth in humid conditions.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Mineral coating integrity and potential clay particle migration
Clay coatings in food-contact cardboard are FDA-recognized indirect additives (21 CFR 176.280) and do not migrate at significant levels under normal use. No reported incidents or safety alerts for this specific product or material class.
Microbial contamination and mold growth
Cardboard is hygroscopic and can retain moisture in humid conditions, supporting mold and bacterial colonization. This is a storage and handling issue, not a manufacturing defect; keep boxes dry and replace if visible growth appears before use.
Ink or printing chemical transfer (if printed)
The product description does not specify ink used; standard food-service cardboard printing inks are regulated and tested for migration. Assume compliance unless product is purchased with unlabeled or non-certified custom printing.
Thermal degradation of coating at high temperatures
Clay coatings may lose water or develop minor surface changes above 200F, though this does not release hazardous substances. Not recommended for direct oven use; mild degradation at pizza serving temperatures (160-180F) is negligible.
Grease barrier saturation and secondary packaging failure
Extended contact with very oily foods may eventually saturate the clay layer, causing visible grease bleed-through. This indicates coating failure and potential food leakage, not chemical hazard, but signals replacement timing.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 78% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
Formulations and coatings change between production runs. Always check the current label before buying.
