Food Safe Grease Proof Paper
Skip until Greenline discloses coating chemistry or certifies PFAS-free
Grease-proof paper typically uses waterproofing treatments; Greenline provides no coating details or PFAS claims. Without disclosure or third-party verification, PFAS risk cannot be ruled out.

The full breakdown
What it's made of and why it matters
Greenline's grease-proof paper is paper substrate coated with an undisclosed water- and oil-repellent treatment. Most commercial grease-proof papers historically relied on fluorinated compounds (PFAS) or paraffin/polyethylene wax coatings; Greenline does not specify which, making independent hazard assessment incomplete. The coating's durability and heat stability depend entirely on its chemistry, which directly affects whether it leaches into food.
The brand's record and disclosure
Greenline maintains a sustainability-focused marketing position but has published no technical data sheets, third-party certifications (such as GOTS, OK compost, or PFAS-free declarations), or independent testing results for this product. The brand's silence on coating composition is a red flag in a category where PFAS-free alternatives exist and are marketed transparently. No major recalls or safety incidents are on public record for this product line.
How it compares in its category
Grease-proof papers span a wide spectrum: some use mineral wax (safer, lower performance), others use polyethylene (disclosed, inert at room temperature), and legacy products use PFAS-based coatings (persistent, bioaccumulative). Greenline occupies the ambiguous middle; competitors like If You Care and some store-brand alternatives openly declare their coatings or carry compostability certifications that imply PFAS avoidance. The lack of transparency is what differentiates this negatively.
If you buy it
Store in a cool, dry place away from direct heat or sunlight before use. Use primarily for room-temperature food wrapping or cold storage; avoid prolonged contact with hot foods or liquids above 50 degrees Celsius, as coating migration risk scales with temperature. Replace sheets if they show visible wear, brittleness, or coating separation. Contact the brand directly requesting coating composition before purchasing in bulk.
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.”
Undisclosed fluorinated coating (PFAS concern)
Grease-proof paper coatings historically reliant on PFAS; Greenline does not disclose alternatives. Without certified PFAS-free or transparent chemistry, this remains a plausible risk. See separate PFAS grade.
Mineral oil or petroleum wax residue
If coating is paraffin or mineral oil-based (alternative to PFAS), low-level migration into fatty foods is possible, particularly at elevated temperatures. Safety threshold exists but is product-specific.
Coating degradation and migration
Unspecified coating durability means unknown susceptibility to wear, moisture, or temperature. Degraded coating particles could theoretically contaminate food if product is reused or stored improperly.
Microplastics from polyethylene-based coating
If coating is polyethylene, mechanical abrasion or heat could generate microplastic particles. Risk is low for food contact but non-zero with repeated use or creasing.
Lack of food-contact certification
No FDA clearance or EU food contact material declaration is documented for Greenline grease-proof paper. Absence of formal approval does not confirm harm, but reduces oversight assurance.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 35% 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.
