Member's Mark Heavy Duty Food Service Foil vs Norpak Grease Resistant Paper Sheet - 12 x 12 Red: which is safer?

Where these two actually differ

• We flag Aluminum leaching from acidic foods on the Sam's Club and not on the Systempak.
• We flag PFAS in grease-resistant coating (reported separately), Coating migration into high-fat foods, Thermal degradation and volatile release and Coating degradation and particulate shedding on the Systempak and not on the Sam's Club.
• The Sam's Club is Aluminum foil where the Systempak is grease-resistant coated paper, coating unspecified, 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 Systempak grade, at 35% confidence against 82%, because it discloses less.
