Eco Friendly Compostable Black Grease Resistant Bags 4 3/4" x 1 1/8" x 6 3/4" GPB3B, Pack Of 100 | by ClearBags
Skip, grease-resistant food bags typically rely on PFAS coatings; manufacturer silence on chemistry is a red flag.
BioPac markets these as 'eco-friendly' and 'compostable,' but provides no disclosure of what coating achieves grease resistance. Grease-resistant food packaging commonly uses PFAS-based treatments (like Teflon-type coating).

Why this grade
Waterproof / stain-resistant treatment
water-repellent coating treatments have historically used PFAS.
Category baseline
food packaging is a category where PFAS exposure is more common.
Vague safety claims only
Uses vague language ("eco-friendly", "clean") without a specific PFAS statement.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 32% 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.
