Reynolds Regular Size Slow Cooker Liners

F · High PFAS

Skip until coating composition is disclosed, slow cooker liners typically use grease-resistant treatments that may contain PFAS.

Reynolds slow cooker liners are single-use polyethylene films designed to repel grease and moisture. The brand does not disclose the chemistry of the coating treatment, and grease-resistant food-contact liners commonly rely on PFAS-based water-repellent coating chemistry.

What we don’t know

This grade is a model-based estimate from public materials, coatings, and brand disclosure at 45% 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.
