Kanga Care Pail Liners are a cylindrical shape tapered slightly towards the bottom to allow more volume and fit your pail perfectly! This pail liner keeps the waterproof TPU (thermoplastic polyurethane) laminate on the inside where the dirty diapers are. The Kanga Care Pail Liners will fit almost any pail size. To use place pail liner in a tall kitchen trash can or diaper pail with a closable lid. Cinch the drawstring down with the toggle for a snug and exact fit. The fabric is cuffed at the top of the liner so when you use it in a pail you will see the fun color folded over the top! Kanga Care uses a water resistant polyester TPU (thermoplastic polyurethane) which is a solvent-free polyester fabric that has been laminated with a thermoplastic polyurethane using a heat bonding process not chemicals making it safer for your family.
