Where these two actually differ
- We flag Non-stick coating composition (undisclosed), Thermal degradation and fume release, Coating migration to food and Microplastic/coating particulate shedding on the Kirkland 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 Kirkland.
- The Kirkland is paper with unspecified silicone or fluoropolymer non-stick coating where the Seventh Generation is bleached paper with silicone coating, which is most of the difference in these two grades.
- The gap is 50 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 Kirkland 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 →
