Milk storage bag, also known as breast milk preservation bag, breast milk bag. It is a plastic product used for food packaging, mainly used to store breast milk. Mothers can express the milk when the breast milk is sufficient, and store it in a milk storage bag for refrigeration or freezing, in case the milk is insufficient in the future or cannot be used for feeding the child on time due to work and other reasons. The material of the milk storage bag is mainly polyethylene, also known as PE. It is one of the most widely used plastics. Some milk storage bags are marked with LDPE (low density polyethylene) or LLDPE (linear low density polyethylene) as a type of polyethylene, but the density and structure are different, but there is not much difference in safety. Some milk storage bags will also add PET to make it a better barrier. There is no problem with these materials themselves, the key is to see whether the additives are safe.
If you need to store breast milk in a breast milk bag for a long time, you can put the freshly squeezed breast milk into the freezer of the refrigerator to freeze for long-term storage. At this time, the milk storage bag will be a good choice, saving space, smaller volume, and better vacuum sealing.
