Kitchsy Kraft Take Out Boxes Disposable Lunch Box
Skip until brand discloses coating chemistry or certifies PFAS-free.
Kraft takeout boxes typically use grease-resistant coatings that may contain PFAS. CKF Inc provides no public disclosure of coating composition or PFAS status, limiting ability to assess risk.

The full breakdown
What it's made of and why it matters
Kitchsy Kraft boxes are kraft paperboard (recycled or virgin fiber) with a grease-resistant coating applied to the interior surface to repel oils and moisture. The coating chemistry is not publicly disclosed by CKF Inc. Grease-resistant coatings on food-contact paperboard are the primary source of PFAS concern in this product category, as they often contain fluorinated compounds to achieve water and oil repellency. Without disclosure, the actual composition (fluorinated vs. non-fluorinated, or PFOA/PFOS presence) cannot be assessed from public information.
The brand's record and disclosure
CKF Inc. is a major manufacturer of disposable food packaging but has not publicly disclosed the specific chemistry of coatings used in Kitchsy-branded boxes. The company has no widely documented certifications (e.g., PFAS-free, third-party testing results) for this product line available in consumer-facing materials. No major recalls or contamination incidents specific to Kitchsy kraft boxes are on public record. The silent stance on coating chemistry is the primary transparency gap.
How it compares in its category
Kraft takeout boxes are standard across the industry and carry similar PFAS risk profiles; many competitors (including some CKF lines) offer PFAS-free certified alternatives or transparent coating disclosures. Compostable or plastic-lined boxes from other brands sometimes provide clearer material transparency. Kitchsy boxes are mid-range in price and widely available, but lag competitors in disclosure standards. If PFAS avoidance is a priority, certified PFAS-free or transparently coated alternatives exist at comparable cost.
If you buy it
Use boxes for room-temperature or warm (not hot) foods; do not microwave or expose to prolonged heat, which could increase leaching of coating components. Keep foods away from prolonged contact with the interior coating, especially fatty or acidic foods that can strip or interact with greases. Replace boxes after each use (they are disposable and not reusable). If you use these regularly, consider requesting the brand to disclose coating chemistry directly; consumer pressure drives industry transparency improvements.
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 grease-resistant coating
Fluorinated grease barriers are common in kraft food packaging; CKF does not disclose whether Kitchsy boxes use PFAS-containing fluorochemicals. Risk is contingent on coating type and food contact duration. Assessed separately as PFAS (25/100 safety).
Ink and colorant migration from exterior printing
No reported contamination from inks on Kitchsy boxes. Exterior printing should not contact food if boxes are used properly. Risk is minimal if interior coating remains intact and food does not touch printed surfaces.
Pulp/fiber degradation and microparticle shed
Kraft paperboard does not shed microplastics (it is paper-based). Fiber shedding into food is not a documented hazard with intact, properly used boxes. Risk only arises if box is wet, torn, or severely degraded.
Chlorine residue or bleaching agents in paperboard
No public record of elevated chlorine or bleach residues in Kitchsy kraft boxes. Kraft is less heavily bleached than white paperboard, reducing residual chemical risk.
Adhesive or coating degradation under heat or moisture
Prolonged heat (microwave, oven) or saturation (wet foods, extended storage) may degrade the interior coating and weaken seams. This could allow coating particles or adhesive components to contact food. Not reported as a safety incident but a use-limit issue.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 45% 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.
