Amazon.com : King Arthur, Pre-Cut Natural & Unbleached Baking Parchment Paper, Heavy Duty, Nonstick, Reusable, Resealabl
Lower concern; bare parchment unlikely to contain PFAS but no brand disclosure.
Natural, unbleached parchment paper is generally lower risk for PFAS than coated nonstick alternatives. No brand statement on PFAS found; traditional parchment does not require fluorinated treatments.

What Amazon.com : King Arthur Resealabl is made of, ingredients and materials
King Arthur's parchment is cellulose paper treated with silicone to create a nonstick surface; unbleached means no chlorine-based whitening agents were used during manufacture. Parchment paper does not leach like plastics or coated metals because silicone is chemically inert at typical baking temperatures (up to ~420°F) and does not migrate into food under normal use. The material itself has no known concern for BPA, phthalates, or microplastics.
What’s concerning
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.
Silicone coating degradation at high heat
Silicone surface can break down above 420, 450°F, potentially shedding microparticles; this is more a functional failure than acute toxicity, but the product is not rated for oven broiler use or direct flame.
Bacterial or mold growth if stored wet
Cellulose paper can support microbial growth if stored in humid conditions or after contact with wet ingredients; this is a storage and handling issue, not inherent to the material.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Chlorine residue in bleached parchment
This product is unbleached, so no chlorine-based whitening agents are present. Bleached parchment alternatives carry this concern; this product avoids it by design.
Mineral oil or wax contamination in pulp
No public record of mineral oil, wax, or recycled fiber contaminants in King Arthur or similar commodity unbleached parchment. Standard food-grade parchment uses virgin pulp or certified recycled fiber.
How is this PFAS grade calculated?
The brand's record and disclosure
King Arthur Baking Company does not publish specific PFAS testing or disclosure for this parchment product, which is standard industry silence rather than a red flag. The brand has no recorded recalls or safety controversies tied to this product line. No third-party certification (e.g., FDA clearance beyond baseline food-contact standards) is claimed, but parchment paper typically meets FDA food-contact material rules as a commodity item.
How it compares in its category
Unbleached parchment paper sits at the lower end of chemical concern compared to bleached parchment (which may retain chlorine residues) or plastic-coated alternatives (silicone-lined or Teflon-type coating). Reusability claims are marketing; parchment degrades with repeated use and should be discarded when it yellows, tears, or loses nonstick grip. Most competitors in this category offer similar unbleached formulations with no meaningful safety differentiation.
If you buy it
Use parchment below 420°F; do not use at broiler temperatures where silicone can degrade. Replace the sheet every 8-12 uses or when it becomes brittle or discolored. Store in a cool, dry place away from direct heat or solvents, which can accelerate degradation. Do not reuse for savory cooking if previously used for sweet items, as residue may impart flavor.
