Where these two actually differ
- We flag Aluminum leaching from acidic foods on the Sam's Club and not on the Sappi Fine Papers.
- We flag PFAS in grease-resistant coating, Coating leaching under heat or acid stress and Microparticle shedding from worn paper on the Sappi Fine Papers and not on the Sam's Club.
- The Sam's Club is Aluminum foil where the Sappi Fine Papers is Cellulose with grease-resistant 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 Sam's Club is the one to buy.
- We are less certain about the Sappi Fine Papers grade, at 35% 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 →
