Skip, disposable liners often use PFAS-based water-repellent coating coatings; no PFAS claim or transparency from brand.
Syntus crock pot liners are marketed as 'leak-proof,' a red flag for grease-resistant coatings that commonly contain PFAS. The brand provides no material disclosure, PFAS-free claim, or third-party verification.

Why this grade
Waterproof / stain-resistant treatment
water-repellent coating treatments have historically used PFAS.
Category baseline

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 28% 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.
