PFAS score
Great Value · Slow Cooker Liners
Extra Large Roaster Liners Fits 1622 Qt Oval Roasters
Lower-concern single-use product, but coating composition unspecified, moderate uncertainty remains.
Great Value roaster liners are single-use plastic films with unknown coating composition. No public PFAS disclosures exist for this product. Roaster liners are typically food-contact films where PFAS concerns are lower than in durable nonstick cookware, but the brand provides no transparency on treatment chemicals.

What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 55% 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.
