Parchment Paper Roll 50 sq ft up&up vs Baking Paper, Parchment, 70 Square Feet: which is safer?

Where these two actually differ

• We flag Thermal degradation of silicone or wax coating, Mineral oil or wax migration at high temperatures and Coating separation or flaking into food on the up&up and not on the If You Care.
• We flag Paper degradation and particulate shedding on the If You Care and not on the up&up.
• The up&up is Paper with silicone or wax coating where the If You Care is silicone-coated parchment paper, which is most of the difference in these two grades.
• The gap is 65 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 up&up grade, at 45% confidence against 82%, because it discloses less.
