Each Spectra Disposable Milk Collection Bag when filled with breastmilk, will stand upright allowing accurate readings from the measurement scale. After filling a milk bag, Spectra highly recommends labeling each bag with the correct date of use which is located on the front. It’s important to remember to leave at least 1 inch of milk from the seal when storing bags in the freezer as breastmilk will expand as it freezes.
PLEASE NOTE: These are for storage use only. You will require an adapter to pump directly into the bags. Adapter is not included.
