Kirkland Signature Plastic Wrap 11-7/8 x 750', 2-Pack
Lower PFAS concern since standard polyethylene 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 disclose PFAS absence or coating details, leaving uncertainty about proprietary additives.

What Kirkland Signature Plastic 750', 2-Pack is made of, ingredients and materials
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.
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.
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.
Microplastics
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.

Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
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.
BPA & bisphenols
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.
Source, FDA ↗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.
How is this PFAS grade calculated?
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 has lower concern for plasticizer-related hazards 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 presents lower concern for phthalate-related hazards compared to PVC cling wrap, but offers less cling; it also presents lower concern for PFAS-related hazards compared to 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.
