Many mothers have an excess of breast milk and either pump it or want to collect milk for various reasons, and they should store it safely. The 44 breast milk storage bags from Cangaroo are perfectly suited for this purpose. Breast milk has the ability to inhibit bacterial growth, allowing it to be stored longer than commercially produced milk, which must be used immediately. The Cangaroo breast milk bags are made from LDPE food-grade material and are free from Bisphenol. They are single-use items that are pre-sterilized and specifically designed for freezing breast milk. This allows them to be frozen in an upright position, saving space, and they are intended for home use only. Breast milk can be stored in the refrigerator in a separate freezer compartment for one to two weeks, and for six months or longer in the freezer.
