Our award-winning Breastmilk Storage Bags are perfect for parents looking to store a bank of breastmilk in the fridge or freezer, without taking up too much space. Leakproof, even when laid flat, our handy bags can store frozen breastmilk for up to 6 months and can be pumped directly into with any Lansinoh Breast Pump, saving time and preventing any messy milk transfers of spills.

Made from food-safe polyethylene, our freezer bags for breastmilk are tough and flexible, so they won't leak, even when laid flat. Each milk storage bag comes complete with a hygienic, tamper-evident, and secure tear-away top to ensure no toxins reach the breastmilk. Plus, the write-on tab makes it easy to keep track of how long the breastmilk has been stored, by noting down the date.

Simply tear the perforated seal and either pour your breastmilk into the bag or pump directly using a Lansinoh breast pump. Gently squeeze out any air before sealing the top of the bag and write the date and amount expressed on the top tab. NHS guidelines state breast milk can be stored in the fridge for up to 8 days or in the freezer for up to 6 months, either laid flat or upright.


TIP: Place a piece of kitchen roll between each bag before freezing to avoid any moisture on the outside of the bag freezing and sticking the bags together.
