Signature Kirkland Non-Stick Parchment Paper vs Baking Paper, Parchment, 70 Square Feet: which is safer?

Where these two actually differ

• We flag Coating thermal degradation and fume release, Microplastic or coating particle shedding into food and Migration of coating additives into fatty foods on the Kirkland and not on the If You Care.
• We flag Paper degradation and particulate shedding on the If You Care and not on the Kirkland.
• The Kirkland is paper with non-stick coating, composition unspecified where the If You Care is silicone-coated parchment paper, which is most of the difference in these two grades.
• The gap is 70 points, wide enough that this is not a close call, and the If You Care is the one to buy.
• We are less certain about the Kirkland grade, at 35% confidence against 82%, because it discloses less.
