MilkWorx Breast Milk Storage Bags are created to make pumping, storing, and freezing breast milk simpler and more dependable. Each bag is pre-sterilized and made from BPA-free materials to help keep your milk safe for your baby. The durable construction and secure double-zip seal help protect against leaks, whether you’re storing milk in the refrigerator, freezer, or on the go. A wide pour spout moved to the bottom of the bags where leaks are most likely to occur allows for easy transfer of milk with less mess and less waste. Not only do these bags give you the little reminder you need for how amazing you're doing, they're functionally designed to stand upright for filling and lay flat for storage, these bags help maximize freezer space while keeping milk organized and easy to label.
