Milk storage bags are specially designed pouches used for storing breast milk. They are typically made from food-safe plastic and are available in various sizes. These bags are convenient for mothers who want to express and store milk for later use, ensuring that the milk remains fresh and safe for their babies. These bags often come with a double zipper seal to prevent leaks and contamination. Many milk storage bags are pre-sterilized, making them ready for immediate use. They can be easily labeled with dates and quantities, helping parents keep track of their milk supply efficiently.
