What kind of container should I use to store expressed breast milk?

Before you pump or handle breast milk, wash your hands with soap and water. Pumping milk also is called expressing. Store the expressed milk in a clean, capped food-grade glass container. Or use a hard plastic container that's not made with the chemical bisphenol A, also called BPA. You also can use special plastic bags designed for milk collection and storage.

Don't store breast milk in disposable bottle liners or plastic bags made for general household use.
