A pail liner is used inside your nappy storage bucket/basket. The stretchy elastic collar fits snug over the bucket rim and the bag itself can hold about 25 nappies (size 73 x 63 cm). The main advantage of using a pail liner is that it makes transferring your nappies into the washing machine really easy with no need to handle them. Simply put the whole lot in the machine and leave the bag open so everything can escape in the wash. It helps to have two pail liners so that you always have one to hand. The pail liner can also be used for storing any wet swim suits or other laundry. As with nappy covers, pail liners dry quickly but should not be left in direct sunlight as this will damage the waterproof fabric.
