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.
