Sealpac · Butcher & Deli Paper
Member's Mark Unbleached Parchment Paper 205 sq. ft. 2 pk.
Parchment paper typically uses silicone; PFAS risk unclear without testing.
Unbleached parchment paper is coated for water and grease resistance. Brand does not disclose coating details or PFAS status; silicone-coated parchment is generally lower concern than Teflon-family coating-based alternatives, but confirmation requires third-party testing.

The full breakdown
What it's made of and why it matters
Member's Mark Unbleached Parchment Paper is kraft paper (unbleached pulp) coated with silicone on both sides to create a non-stick, grease-resistant surface. Unbleached means it avoids chlorine-based bleaching residues, reducing exposure to dioxins and related compounds that have historically contaminated bleached parchment. The silicone coating is food-contact approved in the US and EU, but modern silicone coatings sometimes contain PFAS compounds as surfactant aids during manufacturing, though this is not disclosed on the package.
The brand's record and disclosure
Sealpac (the manufacturer) does not publicly disclose PFAS testing results or commitments to PFAS-free sourcing for this product line. Member's Mark (Costco's private label) has no established record of transparency on PFAS in food-contact paper products. Neither brand lists third-party certifications (e.g., FDA testing, NSF, Cradle to Cradle) specific to PFAS or chemical safety on packaging. This silence does not confirm a problem, but limits consumer ability to verify claims.
How it compares in its category
Unbleached parchment is generally considered safer than chlorine-bleached versions because it skips the bleaching step, which historically introduced trace dioxins. Most bulk parchment papers on the market use silicone coatings (not Teflon-type coating), making silicone the standard risk profile. Some premium brands (e.g., If You Care) test for PFAS and market PFAS-free silicone; Sealpac does not advertise this distinction, placing it in the middle tier of transparency.
If you buy it
Use parchment up to 400-425°F (oven-safe limit for silicone); do not use directly over open flame or on stovetop. Replace rolls every 1-2 years or if the surface becomes visibly worn, torn, or sticky, as degradation may increase leaching. Store in a cool, dry place away from heat to prevent silicone breakdown. If you want lower PFAS risk, seek brands that test and label PFAS-free silicone coatings.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Teflon-type coating or silicone coating integrity
Product uses silicone (not Teflon-type coating), which is safer at normal oven temperatures, but no data on this specific brand's coating durability or potential for particle shedding over repeated use.
Microplastic or silicone particle migration
No recalls or published studies of silicone shedding from unbleached parchment at normal cooking temperatures; risk is theoretical and not established for this product.
Dioxin or bleaching residues
Unbleached formulation avoids chlorine bleaching, which historically introduced trace dioxins in some parchment papers; this product carries lower residual risk than bleached alternatives.
Thermal degradation of coating above safe limits
Silicone coatings can begin to degrade above 425-450°F; overheating is user error rather than product defect, but no manufacturer guidance is visible on packaging for this SKU.
PFAS in silicone surfactants (manufacturer undisclosed)
Silicone coatings sometimes contain PFAS aids; Sealpac does not test or declare PFAS content, leaving exposure status unconfirmed. See separate PFAS grade (25/100).
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 45% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
