Norpro Natural Parchment Paper
Silicone-coated parchment poses lower risk, but coating transparency would help.
Parchment is cellulose based and typically coated with silicone for grease resistance, not Teflon-type coating or known Teflon-family coating. Norpro offers no PFAS statement, and some manufacturers historically used PFAS in grease treatments.

What Norpro Natural Parchment Paper is made of, ingredients and materials
Norpro Natural Parchment Paper is silicone-coated parchment, not the older bleached sulfite base treated with silicone. The silicone coating provides non-stick properties without relying on fluorinated compounds like Teflon-type coating (Teflon). The paper base itself is pulp-derived and chemically inert at normal baking temperatures (up to roughly 400-420°F). Silicone coatings are food-contact-approved by the FDA and do not off-gas volatile organic compounds (VOCs) at typical kitchen use temperatures.
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.
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
Silicone coating leaching at high heat
Silicone is stable at normal baking temperatures but prolonged exposure above 450°F may degrade the bond between paper and coating, allowing trace silicone oligomers to migrate into food. No established recall or contamination case for this brand, but risk exists if product is misused at very high temperatures.
Silicone particle shedding
Heavy or aggressive use (folding, high heat, abrasion during food removal) can cause microscopic silicone particles to shed into baked goods. This is not acutely toxic but represents undesirable food contact. Visually inspect paper before each use and discard if surface appears degraded.
Coating adhesion and delamination over time
Repeated heating and cooling cycles can cause the silicone layer to separate from the paper base, compromising non-stick performance and increasing shed risk. No long-term durability data is published by Norpro; consumer reviews suggest variable lifespan (3-6 months of regular use).
What’s reassuring
Bleach residue or chlorine byproducts in paper base
Norpro does not disclose whether the parchment base is chlorine-bleached or oxygen-bleached. Industry standard suggests chlorine-free processing, but no independent testing of this product for dioxins or chlorinated residues is publicly available. FDA-approved manufacturing processes should render any residual chlorine minimal.
Heavy metals
Silicone coatings do not typically contain aluminum, lead, or cadmium if sourced from reputable suppliers. Norpro's manufacturing standards are not independently verified, but the brand operates under FDA food-contact material regulations.

The brand's record and disclosure
Norpro (a Prestige brand subsidiary) does not publish detailed material safety data sheets or independent certifications for this specific product. The brand has not publicly addressed PFAS content or committed to fluorine-free sourcing. No safety recalls, contamination incidents, or third-party testing issues are on public record for this line. Marketing language emphasizes 'natural' origin but lacks transparency on coating sourcing or manufacturing controls.
How it compares in its category
Silicone-coated parchment is a mid-range safety choice within baking liners. It sits above older chlorine-bleached parchments and Teflon-type coating non-stick papers (which can off-gas fumes above 500°F) but below uncoated or minimally processed alternatives. Many commercial bakeries and home cooks choose silicone-coated parchment for its balance of non-stick performance and material stability. Glass baking dishes and cast iron are lower-contamination options if PFAS or coating leaching is a primary concern.
If you buy it
Do not exceed 425°F; silicone coating remains stable at this threshold but prolonged exposure to higher heat may degrade the coating and increase leaching potential. Replace if the paper shows visible pitting, browning, or coating separation. Store in a cool, dry place away from strong solvents or oils; silicone coating is inert but can absorb odors if damaged. Wash hands after handling to avoid transferring any silicone particles to food, though ingestion of small amounts is not acutely toxic.
