Greaseproof Paper
Greaseproof coating type unclear. Skip if PFAS-concerned.
Glad greaseproof paper likely uses silicone or wax coating for grease resistance, but the specific treatment is not disclosed. Without brand transparency on PFAS content, caution warranted.

The full breakdown
What it's made of and why it matters
Glad greaseproof paper is cellulose base stock coated with either silicone or wax to repel grease and moisture. Silicone coatings are inert at room temperature but can degrade under high heat or prolonged contact with fatty/acidic foods, potentially releasing microscopic silicone particles. Wax-based coatings (paraffin or mineral wax) are inherently food-safe but less heat-resistant and may transfer wax residue to foods in contact with hot items. The exact coating formulation Glad uses is not publicly disclosed.
The brand's record and disclosure
Glad, owned by Clorox, does not publicly specify whether its greaseproof paper uses silicone or wax coatings, nor does it publish independent food-safety or migration testing data. The company has no known recalls or regulatory actions specific to greaseproof paper chemistry. Glad provides minimal transparency about coating composition or PFAS presence, which is consistent with industry-wide opacity on this product class but limits informed choice.
How it compares in its category
Greaseproof papers vary widely: some manufacturers explicitly state wax-only formulations (often parchment marketed for baking), while others use silicone or undisclosed blends. Glad's silence on coating type places it in the middle of the market for transparency. Alternatives like If You Care (certified chlorine-free, wax-coated) or unbleached parchment from specialty suppliers offer clearer ingredient labeling, though at higher cost and potentially lower grease resistance.
If you buy it
Use Glad greaseproof paper for room-temperature and warm (below 120°F) food contact only; do not wrap hot foods directly or use in ovens above 350°F, as coating stability is unknown. Replace if the paper becomes dark, brittle, or shows visible breakdown. Store in a cool, dry place to prevent moisture-driven degradation. For fatty foods (bacon, pastries), limit contact time to under 24 hours to reduce any risk of coating leaching into high-fat matrices.
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.”
Coating material leaching (silicone vs. wax unknown)
Glad does not disclose its coating chemistry. If silicone-based, microscopic particles could migrate to high-fat or acidic foods under heat; if wax-based, the coating is safer but less heat-resistant. No recalls or safety testing publicly available for this brand.
Heat-induced coating degradation
Greaseproof coatings degrade at elevated temperatures. Using Glad paper in ovens or wrapping hot foods increases risk of coating breakdown and potential contact with food. Exact temperature limits are not specified by the manufacturer.
PFAS in coating (unconfirmed)
Some greaseproof papers historically used PFOA or other PFAS as water and oil repellents. Glad's coating formulation is proprietary and not disclosed; PFAS presence cannot be ruled out without independent testing. Graded separately per instructions; concerns warrant precaution if you are PFAS-sensitive.
Microplastic or particle migration from coating
No established reports of visible microplastics from Glad greaseproof paper. However, silicone coatings can shed microscopic particles under mechanical stress or heat; risk is theoretical unless coating visibly deteriorates.
Bleach or chemical residues in base paper
Glad greaseproof paper is not marketed as unbleached or chemical-free. Standard bleaching processes (chlorine or oxygen-based) are regulated and do not typically leave unsafe residues, but no third-party testing is available for this product.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 45% 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.
