What Amazon.com: King Arthur Parchment Paper is made of, ingredients and materials
King Arthur parchment paper is cellulose-based paper with an applied water- and grease-repellent coating. The specific chemistry of that coating is not disclosed by the brand on product labeling or their website. Water repellence in parchment typically comes from either silicone (lower PFAS risk) or fluorocarbon treatments (higher PFAS risk), making transparency essential for informed choice.
What’s concerning
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
PFAS
Without disclosure of fluorocarbon vs. silicone treatment, PFAS content cannot be ruled out. This is the primary reason to exercise caution.
Source, ATSDR ↗Coating transfer to food under heat
Any water-repellent coating can migrate into fatty foods or under sustained high heat. Risk increases if coating type and thermal stability are unknown, as with this product.
What’s reassuring
Bleaching residues in paper substrate
No record of dioxin or chlorine residues in King Arthur parchment. Standard food-grade paper production limits this risk, though unbleached alternatives eliminate it entirely.
Mineral oil or hydrocarbon contamination
No published incidents or testing results identify mineral oil in this product. Parchment made under standard FDA food-contact rules is not expected to have this issue.
Off-gassing or odor from coating
No consumer complaints or test data on record for odor or fume release during typical baking. Risk is low at normal oven temperatures (below 420°F).
How is this PFAS grade calculated?
The brand's record and disclosure
King Arthur Baking Company has not published PFAS disclosure, safety certifications (e.g. FDA migration testing), or coating composition details for this product. The brand markets itself as heritage and quality-focused but does not align with modern transparency standards for food-contact materials. No recalls or contamination incidents are on record for this specific SKU.
How it compares in its category
Most major parchment brands (Reynold's, If You Care, unbleached alternatives) now disclose whether coatings contain PFAS or state PFAS-free claims. King Arthur's silence places it below category leaders in transparency. Unbleached and silicone-coated parchments from competitors offer clearer ingredient disclosure, though cost is typically higher.
If you buy it
Use only up to 420°F (manufacturer limit typical for parchment), as high heat can degrade the coating and increase leaching risk. Do not reuse sheets repeatedly; discard after one or two uses. Store in a cool, dry place away from direct sunlight. If the coating shows visible wear, yellowing, or darkening, discontinue use and replace.
