King Arthur Pre-Cut Natural & Unbleached Baking Parchment Paper
Skip unless you confirm the brand's coating is PFAS-free, they don't disclose it.
King Arthur/Culprit's parchment paper is marketed as 'natural & unbleached' but provides no transparency about its grease-resistant coating composition. Parchment paper typically requires water/grease-repellent treatment, historically a PFAS risk. Without lab data or a direct PFAS-free claim, the coating's contents remain unknown.

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.
