Kirkland Signature Non Stick Parchment Paper
Skip until coating composition is disclosed by Kirkland.
Parchment paper with non-stick coating, but brand provides no coating details or PFAS statement. Silicone coating is likely, but Teflon-family coating risk cannot be ruled out without disclosure.

What Kirkland Signature Non Parchment Paper is made of, ingredients and materials
Kirkland Non-Stick Parchment Paper is paper substrate with an applied non-stick coating that Kirkland does not publicly specify as silicone, Teflon-type coating, or another Teflon-family coating. The coating enables release from food and baking surfaces without added fat. Without transparent ingredient disclosure, you cannot verify whether the coating contains legacy PFAS (like PFOA), newer PFAS replacements, or non-fluorinated alternatives. The chemistry of the coating determines both safety and performance longevity.
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.
Non-stick, chemistry undisclosed
Marketed as non-stick without stating the coating chemistry.
Non-stick coating composition (undisclosed)
Kirkland does not specify whether the coating is Teflon-type coating, silicone, or a Teflon-family coating alternative. Undisclosed coatings may contain PFAS or PFAS replacements; without transparency, residual monomer or degradation products cannot be ruled out.
Thermal degradation and fume release
If the coating is Teflon-type coating-based or contains Teflon-family coating, overheating above 500°F can produce fumes (polytetrafluoroethylene decomposition). Risk is low at normal baking temperatures but increases with broiling or direct flame contact.
Coating migration to food
Non-stick coatings can shed microscopic particles or monomers into fatty foods (oils, butter, fatty meats) or acidic foods, especially if the coating is worn or degraded. Degree of migration depends on coating chemistry and food contact time.
Microplastic/coating particulate shedding
Non-stick parchment coatings may shed visible or microscopic particles over time with repeated use, creasing, or heat cycling. Some users and researchers have documented white or gray coating particles on food; health impact of ingestion is unclear but constitutes a contaminant pathway.
What’s reassuring
Bleaching and sizing chemicals in paper substrate
Kirkland does not disclose whether the paper is chlorine-bleached or processed with problematic sizing agents; generic food-grade parchment paper typically meets FDA limits, but no specific testing for this product is on record.
How is this PFAS grade calculated?
The brand's record and disclosure
Kirkland Signature (Costco's private label) has not publicly committed to PFAS-free formulations across its cookware and food-contact product lines, nor does it disclose coating chemistry on product labels or websites. The company has not faced major recalls tied to parchment paper, but its silence on non-stick coating composition is consistent with an industry-wide pattern of opacity. Costco/Kirkland has lagged peer retailers in demanding supplier transparency on PFAS alternatives.
How it compares in its category
Uncoated parchment paper (such as If You Care or Naturepedic brands) carries no synthetic coating risk and is widely available at similar or lower cost. Pre-silicone-coated alternatives (like King Arthur Baking Company parchment) explicitly label silicone as the coating, offering more transparency. Some brands market PFAS-free non-stick coatings, though verification is limited. Kirkland's lack of disclosure places it in the middle-to-lower transparency tier.
If you buy it
Use at temperatures below 420-450°F (typical range for Teflon-family coating coatings to minimize thermal degradation and potential fume release); avoid direct flame. Replace the sheet if you see visible peeling, browning, or coating separation. Store in a cool, dry place away from prolonged sunlight. Consider rotating purchases toward uncoated parchment or brands with explicit coating disclosure to reduce uncertainty.
