Parchment paper, butcher paper etc can have a variety of different treatments used. PFAS is a common one. Silicone or a combination of PFAS and silicone is another one. Acid treated without a coating is less common although that was the original parchment paper back in the day. Personally, I use "If you care" brand from whole foods which has been independently tested to have the least PFAS.

This voluntary phase-out doesn't include parchment paper you use at home. It's for food packaging
