Reynold’s slow cooker liners help take the mess out of slow cooking by making clean-up a snap. Before tossing in your ingredients and turning it on, place a liner in your slow cooker. Once your meal is served, remove the liner, and clean-up is done! The liners prevent a baked-on mess and eliminate soaking and scrubbing your slow cooker after a meal. They are made with a special heat resistant nylon, BPA-free material that holds in even the heartiest ingredients without breaking or puncturing.
