Kirkland Signature 12" Plastic Food Wrap, 3000 ft
Polyethylene film with a release agent of unstated chemistry, and no PFAS statement from the brand.
Kirkland's plastic wrap is polyethylene with an undisclosed slip agent to prevent sticking during unroll. The slip agent chemistry is not stated. Polyethylene itself is not a material linked to PFAS, but commercial cling wraps sometimes use PFAS-based slip additives. Kirkland has no PFAS statement on record.

What Kirkland Signature 12" Plastic Food Wrap, is made of, ingredients and materials
Kirkland 12" wrap is polyethylene (PE) film, the most common food wrap plastic globally. PE is chemically inert at room temperature and does not contain BPA or phthalates by design. The slip/release agent (typically silicone or fatty acid derivative) enables the wrap to unroll smoothly; if fluorinated, this could introduce PFAS, but Kirkland has not disclosed the slip coat chemistry. PE does not leach at temperatures typical of food storage (fridge/pantry), though direct contact with hot foods or prolonged microwave use is not recommended for any PE film.
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.
Microplastic shedding during use
PE film can degrade and fragment if repeatedly stretched, heated, or exposed to UV light, though food wrap sees minimal mechanical stress during typical application. Risk is low under normal storage and wrapping conditions.
Slip coat leachables (fluorinated or otherwise)
Kirkland does not disclose slip agent chemistry. If the coating contains fluorinated compounds, PFAS transfer risk exists; if silicone or fatty-acid based, risk is minimal. Undisclosed formulation is the limitation, not an established hazard.
Thermal degradation at elevated temperature
PE film begins to soften above 80-100°C (176-212°F) and should not contact hot foods or be used in microwave ovens. Direct contact with hot surfaces can cause melting and potential ingestion of film fragments, though this is user error rather than product defect.
What’s reassuring
BPA & bisphenols
Polyethylene film does not contain BPA or BPS by manufacturing standard. No recalls or warnings exist for Kirkland wrap on this hazard.
Source, FDA ↗Phthalate plasticizers
PE is naturally flexible and does not require phthalate plasticizers. This product class does not use them.
How is this PFAS grade calculated?
The brand's record and disclosure
Kirkland Signature (Costco's house brand) does not publish material safety data sheets or PFAS disclosure for this product. Costco has faced no major recalls tied to food wrap safety in recent years. The brand maintains lower public transparency than premium alternatives (e.g., If You Care, Stretch-Tite) but offers no known history of hazardous formulations in plastic wrap. Absence of disclosure is typical for commodity food wrap and does not indicate a safety failure.
How it compares in its category
Kirkland PE wrap is functionally equivalent to store-brand PE wraps from other retailers (Glad, Saran, Trader Joe's). It carries the same material hazard profile as mainstream alternatives, inert plastic with undisclosed slip coat. Premium brands that disclose non-fluorinated slip agents (If You Care) offer marginal additional transparency but similar practical performance. Price and roll length (3000 ft) place it as a bulk value option with no safety disadvantage over name brands.
If you buy it
Use only on room-temperature and cold foods; do not cover hot dishes or place wrap in direct microwave contact. Store in a cool, dry place away from heat and light to prevent film brittleness. Replace the roll if the film becomes tacky, discolored, or embrittled, which signals potential slip coat breakdown (uncommon but indicates end of shelf life). Standard food-contact warnings apply, wash hands before use and keep wrap away from open flame.
