Kirkland Signature Plastic Wrap 11-7/8 x 750', 2-Pack
Lower PFAS concern, standard PE cling wrap rarely requires fluorinated treatments, but Kirkland makes no transparency claim.
Kirkland Signature plastic wrap is typically polyethylene, a non-fluorinated material with minimal inherent PFAS risk. However, Kirkland does not publicly disclose PFAS absence or coating details, leaving some uncertainty about proprietary additives.

The full breakdown
What it's made of and why it matters
Kirkland Signature Plastic Wrap is polyethylene (PE) film, a non-plasticized thermoplastic polymer chosen for food contact because it does not require phthalates or BPA to achieve flexibility. PE is chemically inert at room temperature and does not leach into food under normal storage conditions. The 11.75-inch width and 750-foot length indicate this is a standard household cling wrap designed for wrapping food, leftovers, and cold/ambient storage rather than microwave or oven use.
The brand's record and disclosure
Kirkland Signature (Costco's house brand) does not publish detailed material safety data sheets or chemical disclosure statements for plastic wrap products. No recalls or safety incidents involving this specific product are on record. The brand does not market transparency around PFAS, flame retardants, or other additives in food-contact plastics, which is typical for commodity wrap manufacturers but limits independent verification of formulation changes.
How it compares in its category
Polyethylene cling wrap is among the safest food-contact plastics because it avoids plasticizers and does not require fluorinated coatings for cling performance. Competing brands (Glad, Saran, store brands) typically use the same PE chemistry with similar hazard profiles. PE wrap is safer than PVC cling wrap (which may contain phthalates) but offers less cling; it is also safer than treated paper wraps that may contain PFAS-based water-repellents.
If you buy it
Do not use this wrap in microwave ovens or contact with hot foods above 130-140°F, as PE begins to soften and may degrade. Store in a cool, dry place away from direct sunlight to prevent the film from becoming brittle or sticky. Replace the roll every 1-2 years or when the film becomes difficult to unroll or tears easily. Keep away from fatty foods when possible, as lipids can accelerate minor migration of any slip agents in the film.
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.”
Polyethylene film degradation under heat
PE wrap is not microwave-safe and will soften, tear, or potentially release volatile compounds if exposed to temperatures above 140°F. This is a user error risk rather than a chemical contamination risk, but important to label correctly.
Slip agents and processing residues
PE cling wrap typically contains small amounts of slip agents (often oleamide, erucamide, or mineral oil) to prevent the roll from sticking to itself. FDA-approved slip agents used in PE film are not documented to leach into food at rates of concern, and no reported incidents exist for Kirkland wrap specifically.
Microplastics from degradation or tearing
If wrap tears or fragments during use and pieces contact food, ingestion of microplastics is theoretically possible. The long-term health significance of dietary microplastics is still being studied, but risk is minimized by careful handling and not leaving wrap fragments in contact with food.
BPA or phthalate leaching
Polyethylene does not require BPA, BPS, or phthalates for its cling or flexibility properties. No evidence of these chemicals in PE wrap exists, and regulatory oversight of food-contact plastics in the US is designed to prevent their presence.
Antioxidant or stabilizer residues
PE film typically contains food-grade antioxidants (such as hindered phenols) and UV stabilizers to prevent degradation during storage and use. These are approved for food contact and do not leach into food at detectable or harmful levels under normal storage conditions.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 82% 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.
