Greenline · Grease-Resistant Paper Products

Custom Greaseproof Paper

F · High PFAS

Skip without coating transparency; greaseproof typically uses PFAS.

Verdict: SkipGreenline's silence on coating transparency combined with standard PFAS use in greaseproof paper makes this unverifiable for safety.

Greaseproof paper typically requires fluorinated coatings to repel grease and moisture. Greenline provides no coating specification or PFAS disclosure, raising concern.

The full breakdown

What it's made of and why it matters

Greaseproof paper is cellulose-based paper treated with a hydrophobic (water and grease resistant) coating. Greenline does not publicly specify which coating chemistry is used on this product. Standard greaseproof coatings historically rely on PFAS "forever chemicals" (PFAS) to achieve grease resistance, though some manufacturers have begun switching to non-fluorinated alternatives like silicone, wax blends, or clay. Without disclosure, you cannot determine whether this product contains legacy PFAS, newer alternatives, or their relative safety profiles.

The brand's record and disclosure

Greenline does not publicly disclose coating formulation, PFAS content, or certification against PFAS-containing inputs on their website or product labeling available in public sources. No third-party certifications (e.g., Nordic Swan, Blue Angel, or PFOA-free claims) are documented for this product. The brand's silence on this known risk area in greaseproof paper suggests either lack of due diligence or unwillingness to disclose, neither of which supports consumer confidence.

How it compares in its category

Greaseproof papers as a category carry inherent PFAS exposure risk because the grease-barrier function traditionally requires fluorinated chemistry. Competing brands such as If You Care (wax-coated, PFAS-free certified) and Footprint (clay-based alternative coatings) explicitly market non-PFAS options. Greenline's lack of transparency puts it below category leaders that disclose their coating chemistry and certifications, making it harder to assess than branded alternatives with stated standards.

If you buy it

Do not use with foods intended for infants, young children, or frequent consumers. Greaseproof paper should not be microwaved or used in contact with hot, fatty foods for extended periods, as heat can accelerate migration of coating components into food. Store in a cool, dry place and replace immediately if the coating shows visible wear, cracking, or darkening. If avoiding PFAS is a priority, source a greaseproof paper brand that explicitly certifies PFAS-free coating or use untreated parchment or cloth alternatives.

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.”

Possible

Coating leachates (non-PFAS)

Even if Greenline's coating is PFAS-free, alternative coating chemistries (silicone, wax, clay) can leach minor compounds under heat or prolonged fatty food contact. No safety data sheet or migration testing is publicly available for this specific product.

Possible

Microplastics from coating degradation

If the greaseproof coating is a polymer or synthetic base, mechanical wear (folding, repeated use, heat) can generate small coating particles. No studies specific to Greenline's coating durability under typical kitchen use are on record.

Possible

Unlabeled additives in coating

Greaseproof coatings often contain plasticizers, stabilizers, or slip agents that are not disclosed on retail packaging. Without a full formulation statement or third-party certification, presence and identity of these additives cannot be verified.

None known

Heavy metals in bleaching or processing

Paper manufacturing historically used chlorine bleaching and may involve trace heavy metals. No recalls or testing results for Greenline greaseproof paper specific to lead or cadmium are documented, and modern bleaching standards have largely reduced this risk.

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.
