Signature Food Wrap Stretch-Tite Premium Size: 12 vs Reynolds Heavy Duty Aluminum Foil Roll: which is safer?

Where these two actually differ

• We flag Fluorinated polymer barrier coatings (food-contact surface), Plastic migration under heat or extended contact, Microplastic or coating fragment shedding during use and Cumulative exposure through repeated use 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 film with unknown moisture/grease barrier 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 45% confidence against 82%, because it discloses less.
