20 Count Disposable Slow Cooker Liners and Cooking Bags
Skip unless the brand confirms PFAS-free; grease-resistant coatings often use PFAS.
These plastic liners resist grease and moisture, functions historically achieved with PFAS-based coatings. The brand provides no material specification or PFAS verification.

What 20 Count Disposable Slow Cooking Bags is made of, ingredients and materials
Slow cooker liners are thin plastic films, typically polyethylene (PE) or polypropylene (PP), coated with a grease-resistant finish to prevent food from sticking and leaking. The coating is the critical unknown, grease-resistant treatments on disposable food-contact bags commonly rely on fluorinated compounds (PFAS) to repel oils, though some manufacturers now use silicone or non-fluorinated alternatives. The plastic substrate itself (PE/PP) is heat-stable up to approximately 220-250°F, which is suitable for slow cooker use (typically 170-210°F). Without the brand's material disclosure, the coating composition cannot be verified from public sources.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
PFAS
Fluorinated compounds are common in grease-resistant food-contact coatings but are not confirmed in this product. The brand's lack of disclosure prevents definitive assessment; assume possible PFAS presence unless brand confirms otherwise.
Source, ATSDR ↗Coating degradation under heat stress
Repeated or prolonged exposure to slow cooker temperatures approaching 210°F may gradually degrade the grease-resistant coating, increasing leaching potential over the product's shelf life. Impact is low if liners are used within specification.
What’s reassuring
Microplastics
No published reports of microplastic generation from intact slow cooker liners during normal use. Torn or heavily degraded liners could theoretically shed particles; proper inspection before use mitigates this.
Source, EPA ↗BPA & bisphenols
PE and PP do not typically contain phthalates or BPA as primary plasticizers; neither compound is expected in these liners at regulatory concern levels. No specific recalls or test data contradict this for the brand's product.
Source, FDA ↗Allergen or irritant residues from manufacturing
No documented sensitivity or allergic reactions linked to slow cooker liners. Standard food-contact plastic manufacturing should remove residual monomers; risk is theoretical and not reported.
How is this PFAS grade calculated?
The brand's record and disclosure
The brand has not publicly committed to PFAS-free formulations across its private-label food-contact products, nor has it disclosed the specific coating chemistry of these liners. No peer-reviewed studies, independent test reports, or product safety recalls specific to slow cooker liners are on record. The brand's silence on PFAS in grease-resistant coatings is typical of large retailers that have not adopted full transparency policies; this is a disclosure gap, not proof of hazard, but it prevents confident assessment.
How it compares in its category
Most disposable slow cooker liners sold at major retailers (including the brand, store brands, and name brands like Reynolds) use similar PE/PP film with grease-resistant coatings; few brands explicitly state PFAS-free status. Lined versus unlined slow cookers avoid the coating issue entirely, and reusable silicone liners eliminate the single-use plastic question but require cleaning. The brand's product is price-competitive but offers no transparency advantage over competitors; purchasing from brands that explicitly market lower concern coatings (such as some premium or eco-focused brands) may be an option if available and affordable.
If you buy it
Use liners only within the slow cooker's normal temperature range (do not exceed 210°F); do not use on stovetop or in ovens. Do not allow liners to come into direct contact with raw acidic foods for extended periods before slow cooking begins, as acidic conditions may increase leaching risk. Replace liners if tears or punctures occur, and discard any that show visible degradation or clouding. If concerned about PFAS exposure, contact directly requesting coating material data; consider switching to unlined slow cookers or reusable silicone alternatives as a precautionary measure.
