Where these two actually differ
- We flag Aluminum leaching from acidic foods on the Sam's Club and not on the Sealpac.
- We flag Coating composition undisclosed (general toxicity risk), Migration of coating into food (oleophilic contact), Thermal degradation (heat exposure) and Microplastics from coating degradation on the Sealpac and not on the Sam's Club.
- The Sam's Club is Aluminum foil where the Sealpac is Paper with grease-resistant coating, composition undisclosed, 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 Sealpac 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 →
