GLAD Parchment Paper Baking Sheet vs up&up Parchment Paper Roll: which is safer?

Where these two actually differ

• We flag PFAS in grease-resistant coating, Silicone migration, Thermal degradation of coating and Microplastics from shedding on the Parchment Paper by Glad and not on the Parchment Paper by Kroger.
• We flag Coating degradation and paper fiber exposure, Thermal decomposition at excessive heat and Mold or bacterial growth if stored improperly on the Parchment Paper by Kroger and not on the Parchment Paper by Glad.
• The Parchment Paper by Glad is bleached paper with silicone and grease-resistant coating where the Parchment Paper by Kroger is silicone-coated paper, which is most of the difference in these two grades.
• These two are level, close enough that price and fit should decide it rather than our grade.
• We are less certain about the Parchment Paper by Glad grade, at 45% confidence against 72%, because it discloses less.
