The material of the breast milk storage bag is mainly polyethylene, also known as PE, which is the most widely used plastic. Some breast storage milk bags are labeled LDPE (low-density polyethylene) or LLDPE (linear low-density polyethylene), which are both types of polyethylene with different densities and structures, but there is not much difference in safety.
