Extra Large Roaster Liners Fits 1622 Qt Oval Roasters
Skip, opaque coating disclosure on single-use plastic roasting liners raises PFAS concern.
Presto does not disclose what coating or material these roaster liners use. Single-use plastic liners in cookware often receive grease-resistant or nonstick treatments that historically contained PFAS.

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.
