Reynolds Kitchens Bulk Slow Cooker Liners

These liners come in a bulk pack of twenty, designed to fit 3- to 8-quart round and oval slow cookers. They are BPA-free and constructed from a nylon blend that resists heat up to 400°F and prevents food from sticking to the sides. Best for large households or batch cooking, this option emphasizes quick cleanup in seconds. A potential limitation is the need to ensure the liner fully covers non-standard shapes to avoid leaks.
30 Pack Slow Cooker Liners, Large Size

This set includes 30 liners measuring 13″ x 21″, compatible with 3- to 8-quart slow cookers. The liners are BPA-free and heat-tolerant up to 400°F, made from a thick nylon blend that resists punctures and leaks. Best for bulk meal prep or frequent use; it’s important to verify the fit for unusually shaped slow cookers to maximize leak protection.
Reynolds Kitchens Slow Cooker Liners, 6 Pack

Six liners measuring 13 x 21 inches fit 3- to 8-quart round or oval slow cookers. They offer easy cleanup and help prevent food from sticking to the sides. Best for occasional cooks or small households that want dependable liners without stockpiling. A limitation to consider is the smaller quantity compared with bulk options.
Syntus Crock Pot Liners, 20 Count

These 20 liners measure 13″ x 21″ and fit most 3- to 8-quart crocks, including round, oval, and rectangular shapes. They’re made from a thicker nylon blend, BPA-free, and heat-safe up to 400°F. Best for users who need a versatile fit across shapes, with the note that rectangular crocks are less common in some households and may require verifying fit.

The 100-count set is designed for high-volume cooks, with liners sized 13″ x 21″ to fit 3- to 8-quart slow cookers. Made from BPA-free material and a robust nylon blend, these liners withstand up to 400°F. Best for large families, meal prep services, or occasional batch cooking at scale. A limitation is the sheer quantity, which may be more than needed for casual users.
Buying Guide: How To Choose Crock Pot Liners
- Size and fit: Confirm the liner dimensions (commonly 13″ x 21″) and whether your cooker is round, oval, or rectangular. Choose a liner that fully covers the inner sides to prevent leaks.
- Material and safety: Look for BPA-free materials and a sturdy nylon blend. Heat resistance up to 400°F is typical and important for long cooking times.
- Pack size and value: Bulk packs save money for frequent users; smaller packs suit occasional cooks. Consider your weekly cooking frequency when selecting quantity.
- Ease of use: Some liners are designed to be unstuck and pulled out individually; others may need careful removal after cooking. Check for puncture resistance to avoid leaks.
- Flavor and texture impact: High-quality liners should not alter the flavor of cooked dishes. BPA-free liners prioritize safety for food contact.
- Shape versatility: If you own rectangular crocks, verify the liners’ compatibility; some sets are optimized for round or oval shapes.
