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 paperboard, a bleached or unbleached paper composite designed for structural strength in food service. The critical component is the grease-resistant coating applied to the interior surface, which repels oils and moisture from foods. Kraft take-out containers in this style typically use either PFAS-based fluorochemical coatings (most common in the industry historically) or alternative barrier systems. CKF Inc has not published material disclosures for this specific SKU, so the coating chemistry remains unconfirmed.
The brand's record and disclosure
CKF Inc is a major North American food-packaging manufacturer with no public commitment to PFAS elimination or transparency on grease-barrier chemistry visible in readily available sources. The company does not appear on major PFAS-free certifications or pledges. No recalls or safety incidents are on record for this specific container line. Without direct contact with the manufacturer, coating composition cannot be verified.
How it compares in its category
Kraft take-out containers are the industry standard for cost and food-contact compliance. Most compete on price; CKF's 450-count bulk option is typical of food-service purchasing. The major differentiator in this category is coating type: PFAS-based coatings dominate because they perform well at low cost, but PFAS-free alternatives (silicone, wax, or clay-based barriers) are increasingly available from premium brands. This product offers no known marketing advantage in safety over peers.
If you buy it
Use for room-temperature or warm foods only; do not microwave or expose to high heat, which may stress the coating. Replace containers if the interior surface becomes visibly worn, cracked, or water-absorbent (sign of barrier failure). Store in a dry location to prevent mold or degradation. Before committing to bulk purchase, contact CKF customer service to request the Safety Data Sheet (SDS) or technical bulletin that specifies the grease-resistant coating chemistry.
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-based grease coating
Kraft take-out containers commonly use PFAS fluorochemical barriers. CKF has not disclosed coating type for this SKU; grease-resistant performance at this price point typically indicates PFAS, but confirmation is required.
Coating degradation and leaching
Kraft paper coatings can crack or wear with repeated use, moisture, or temperature stress. Degraded barriers may allow direct paper contact with acidic or oily foods, leaching paper chemicals or compromising food safety.
Microplastics or particulates from coating wear
No reports of microplastic release from kraft take-out containers in normal use. Coating is bonded to paper and not designed to shed; risk is minimal unless container is physically damaged.
Formaldehyde or adhesive residues
Kraft paperboard may contain formaldehyde-releasing binders or adhesives, but food-contact grades are regulated to low off-gas levels. No specific reports for CKF containers.
Chlorine bleaching residues
Bleached kraft paper uses chlorine in processing. Food-contact paper is rinsed and tested to remove residual chemicals; no accumulation hazard is documented for this product category.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 62% 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.
