Member's Mark Unbleached Parchment Paper 410 sq. ft vs Parchment Baking Sheets | 3 x 24 sheets: which is safer?
Parchment Baking Sheets | 3 x 24 sheets is the clear pick. Member's Mark Unbleached Parchment Paper 410 sq. ft carries a failing PFAS grade, and we never recommend buying a failing product.

Where these two actually differ
- We flag Coating degradation and particulate shedding, Thermal decomposition of coating at high heat, Microplastic/microparticle ingestion from degraded paper and Unknown synthetic additives in coating on the Katom and not on the Seventh Generation.
- We flag Silicone coating degradation and microparticles and Heat-induced breakdown of paper fibers on the Seventh Generation and not on the Katom.
- The Katom is unbleached paper with grease-resistant coating where the Seventh Generation is bleached paper with silicone coating, which is most of the difference in these two grades.
- The gap is 45 points, wide enough that this is not a close call, and the Seventh Generation is the one to buy.
- We are less certain about the Katom grade, at 45% confidence against 82%, because it discloses less.
Both products run through the same public rubric: materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
