Kirkland Signature Culinary Parchment Paper Non Stick 205+205 Sq Ft 2

Bad

Skip until Kirkland discloses non-stick coating chemistry.

Verdict: SkipUnidentified non-stick coating raises PFAS concern; otherwise typical parchment. Use cautiously until Kirkland discloses chemistry.

Parchment paper's non-stick coating is typically Teflon-family coating-based but Kirkland provides no ingredient disclosure. Without transparency or third-party verification, PFAS risk cannot be ruled out.

What’s concerning

♾️

Non-stick, chemistry undisclosed

Marketed non-stick without stating the coating chemistry.

60/ 100
♾️

Category baseline

food packaging is a category where PFAS exposure is more common.

75/ 100
♾️

No PFAS disclosure

No public statement about PFAS in this product.

85/ 100
♾️

Non-stick coating identity (fluorocarbon risk)

Kirkland does not disclose whether the non-stick coating is silicone or fluorocarbon-based. If fluorocarbon, it likely contains PFAS compounds (covered separately in PFAS grade). This opacity is the primary safety concern for this product.

70/ 100
🫧

Coating degradation and micro-particle shedding

Parchment papers with poorly adhered or low-quality coatings can shed micro-fragments into food when heated or cut. No recalls are on record for Kirkland parchment specifically, but degradation risk increases with temperature and acidic foods.

45/ 100
🍳

Migration of coating binders into fatty or oily foods

Fats and oils are known to accelerate leaching of coating polymers from food-contact surfaces. Without knowing the specific binder chemistry, risk cannot be ruled out for high-fat applications (roasting meats, baking pastries with butter).

70/ 100

What’s reassuring

Bleach and brightening agents in paper substrate

Kirkland does not specify whether this cellulose is chlorine-bleached or oxygen-bleached. Food-contact grades are regulated to safe residue limits in most jurisdictions, but unbleached or oxygen-bleached alternatives exist if this is a concern.

95/ 100

Thermal stability of coating at common baking temperatures

Standard food-grade parchment coatings are rated to 420 F; no information suggests Kirkland's coating differs. Testing data specific to this product is not publicly available.

95/ 100

The full breakdown

What it's made of and why it matters

This product is cellulose paper (wood pulp base) coated with an unspecified non-stick agent. Kirkland does not publicly identify the coating chemistry on packaging or their website. Most food-grade parchment uses either silicone or fluorocarbon-based coatings; the lack of transparency here prevents confirmation that fluorocarbons (PFAS compounds) are absent. The paper substrate itself is generally safe, but the coating is where safety concerns concentrate.

The brand's record and disclosure

Kirkland Signature (Costco's house brand) maintains minimal public disclosure on chemical composition for most food-contact products. No independent certifications (e.g., Nordic Swan, Green Seal) appear on this parchment product. Costco has not published a PFAS policy or commitment to phasing out fluorinated coatings in cookware or food-contact items. This silence is notable given industry movement toward disclosure, particularly after PFOA/Teflon-type coating scrutiny in non-stick cookware.

How it compares in its category

Kirkland parchment is standard commodity parchment. Competitors like If You Care and Regency offer certified compostable or silicone-coated alternatives with public transparency about non-PFAS coatings. Pre-cut parchment papers from major brands vary widely: some explicitly state silicone coating; others (including some store brands) remain silent. Price is Kirkland's advantage; safety transparency is not.

If you buy it

Use below 420 F to avoid thermal stress on the coating. Replace the roll if you see browning, tears, or flaking of the non-stick layer, as coating breakdown may release unknowns into food. Store in a cool, dry place; moisture can degrade cellulose. Do not use in direct contact with acidic foods (vinegar, citrus, tomato) for extended periods, as acids can weaken both paper and coating adhesion. Consider contacting Kirkland/Costco to request coating chemistry disclosure before purchasing bulk.
