Skip until CKF discloses coating composition.
Kraft food containers typically use water/grease-resistant coatings, historically PFAS-based. CKF provides no public disclosure on coating chemistry or PFAS status.

No PFAS disclosure
No public statement about PFAS in this product.
The full breakdown
What it's made of and why it matters
This is Kraft paper (bleached or unbleached cellulose pulp) folded into a container with an unspecified water- and grease-resistant coating applied to the interior. Kraft paper itself is inert, but the coating is the critical unknown. CKF does not publicly disclose whether this is PFAS-based (PFOA, PFOS, or GenX alternatives), mineral oil, or wax. The 'microwavable' claim on the label is concerning because many grease-resistant paper coatings degrade or migrate when heated, especially if they contain fluorinated compounds or plasticizers.
The brand's record and disclosure
CKF Inc manufactures disposable food service packaging and has not published ingredient transparency reports or PFAS phase-out commitments on their website or in accessible industry databases. The company has no known certifications (like Food Safe Paper or Green Guard) that would independently verify coating safety. No major product recalls tied to this container line appear in FDA or CPSC records, but absence of recall does not confirm safety of specific chemical coatings.
How it compares in its category
Kraft takeout containers dominate the foodservice market, but competitors (e.g., Footprint, World Centric) increasingly disclose PFAS-free coatings or use certified alternatives like silicone or wax blends. CKF's silence puts this product behind the transparency curve. Compostable or uncoated cardboard options exist for cold/dry foods and avoid the coating question entirely, though they sacrifice grease resistance.
If you buy it
Do not use in microwaves despite the label claim; heat can accelerate coating breakdown and leaching. Use only for cold or room-temperature foods (deli items, baked goods, takeout salads). Replace immediately if the interior coating shows cracks, peeling, or discoloration. Store in a cool, dry place away from oils or fatty residues. Consider this a temporary single-use container; do not reuse for storage or heating.
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.”
PFAS in water/grease-resistant coating
Coating composition is undisclosed. Historically, Teflon-family coating-based grease barriers in food contact paper often contain PFOA or PFOS alternatives; CKF provides no evidence of PFAS-free formulation. Migration risk increases with heat and fatty foods.
Coating degradation and leachate on heating
Labeling as 'microwavable' is misleading. Kraft paper coatings commonly soften, bleed, or release volatile compounds when heated; the unspecified resin is almost certainly not suitable for prolonged microwave use regardless of PFAS content.
Mineral oil or plasticizer migration (if non-PFAS coating)
If coating is mineral oil based, it can migrate into fatty or oily foods. If it includes phthalate plasticizers as a secondary additive, heat and time increase leaching risk. No independent testing of this product's coating is available.
Unlisted additives or pigments in coating
CKF does not disclose whether anti-microbial agents, colorants, or cross-linking resins are present in the coating. No recalls or adverse reports have surfaced, but transparency gaps prevent full assessment.
Microplastic or fiber shedding
Kraft paper containers can shed fibers into food if the substrate is damaged or the coating is thin. This is a mechanical rather than chemical hazard but most common with low-grade or heavily coated papers. No product-specific data exists for this container.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 35% 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.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
