Kirkland Signature All Purpose Cling Film
Lower concern; standard PVC cling film carries minimal PFAS risk, but Kirkland makes no transparency claims.
Kirkland's cling film is PVC-based, a material not typically formulated with PFAS in food-wrap applications. Standard PVC does not require Teflon-type coating or Teflon-family coating coatings. However, Kirkland does not publicly disclose composition or conduct third-party testing, so absolute assurance is not available from the brand.

The full breakdown
What it's made of and why it matters
Kirkland All Purpose Cling Film is polyvinyl chloride (PVC), a widely used plastic for food wrapping due to its strong adhesion and clarity. PVC cling films typically require plasticizers, most commonly diisononyl cyclohexane-1,2-dicarboxylate (DINCH) or legacy phthalates, to achieve flexibility; Kirkland does not publicly disclose which is used. The material is designed for short-term food contact and is not intended for high-heat cooking or long-term storage of fatty or acidic foods.
The brand's record and disclosure
Kirkland Signature (Costco's house brand) has made no public commitments to chemical transparency regarding cling film composition or phthalate phase-out. The brand does not publish safety data sheets or material certifications for this product category. Kirkland has not faced documented recalls or regulatory action specific to cling film, and the product carries standard food-contact compliance markings typical of retail-grade film in North America.
How it compares in its category
PVC cling film is the industry baseline for foodservice wrapping globally; alternatives (polyethylene, polypropylene, silicone-based wraps) are less adhesive or more costly. Kirkland's offering is chemically equivalent to store brands from major retailers and does not stand out as higher or lower risk within conventional PVC cling films. Premium brands like Glad or Saran do not disclose phthalate status either, making true comparative risk assessment difficult without independent testing.
If you buy it
Do not use for covering foods during microwave heating; transfer to microwave-safe dishes instead. Avoid prolonged contact with fatty, oily, or acidic foods (citrus, vinegar, cheese) which can increase plasticizer migration. Replace the roll if the film becomes brittle, discolored, or difficult to unwind, signaling degradation. Store in a cool, dry place away from direct sunlight to prevent adhesive loss and material embrittlement over time.
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.”
Phthalate plasticizers (legacy formulations)
PVC cling films historically used dibutyl phthalate (DBP) and diisodecyl phthalate (DIDP); current Kirkland formulation is not publicly disclosed. If older DINCH or higher-alkyl phthalates are used, migration to fatty foods is low under normal conditions, but risk exists with prolonged contact or heat.
Plasticizer migration during microwave use
Industry and regulatory bodies (FDA, EFSA) have documented that PVC cling film should not contact food during microwave heating. Kirkland product labeling should warn against this, though heat-induced plasticizer leaching into food is the primary non-PFAS chemical hazard.
Vinyl chloride monomer (VCM) residue
PVC cling film manufacturing standards in North America require VCM residue to be minimal and non-detectable in finished product. No specific recalls or concerns for Kirkland cling film have been documented; regulatory compliance is assumed for retail sale.
Coating degradation and microplastic shedding
Over extended storage or with repeated unrolling, PVC cling film can become brittle and shed small fragments. Risk is low during normal use (wrapping food briefly) but increases if film is stored in heat or UV light or if used for long-term food storage.
Adhesive residue transfer to food
The adhesive layer on PVC cling film is designed to remain on the film surface; no established public health concerns exist for adhesive transfer to wrapped food under normal use. Kirkland product meets standard food-contact regulations.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% 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.
