Where these two actually differ

  • We flag PFAS in release agent coating, PVC chlorine leaching (if PVC formulation), Microplastics from degradation and Coating degradation and unknown leachates on the Kirkland Signature and not on the Reynolds Wrap.
  • We flag Aluminum leaching into acidic or salty foods and Sharp edges and mechanical injury on the Reynolds Wrap and not on the Kirkland Signature.
  • The Kirkland Signature is PVC or polyethylene film with undisclosed release agent/coating where the Reynolds Wrap is aluminum foil (bare), 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 Reynolds Wrap is the one to buy.
  • We are less certain about the Kirkland Signature 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 →
