Where these two actually differ

  • We flag Microplastic shedding from heat exposure, Migration of slip-coating additives and Degradation and brittleness over time 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 Polyethylene (PE) film with slip/stretch 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.

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 →
