Breastmilk Storage Bags

Our Breastmilk Storage Bags are perfect for mums to store breastmilk in the fridge or freezer, lying flat or standing up.

You can pump directly into our Breastmilk Storage Bags from any Breast Pump, just tear open the perforated seal and gently slip the neck of the breast pump into the bag. Pull down on the bag slightly to line up the pump neck with the white line on the Breastmilk Storage Bag.

They’re a great way (if possible) for mums to create a bank of breastmilk that can be stored until they are needed for up to 6 months. Made from food-safe polyethylene, they are tough, flexible so they won’t leak and no toxins will reach the breastmilk.

After use our bags can also be recycled, so you can use them knowing that you are helping create a better future world for your baby. Most councils will recycle plastic type 4 (LDPE).

The bags now come with a hygienic, tamper-evident and secure tear away top along with the write on tab making it easy for mums to keep track of how long the breastmilk has been stored.

The bags also have double-sealed side seams for extra strength, and are pre-sterilised, they’re also BPA/BPS free so no harmful substances can contaminate the stored breastmilk.

    • What type of plastic are your bags made of?

      Made of Low Density Polyethylene (LDPE 4), which is recyclable. To check if your council accepts this type of plastic, check your local authority website.
    • Are your bags reusable?

      Lansinoh Breastmilk Storage Bags are designed for one-time use only, however they can be recycled to minimise the impact on the environment.
    • How do I thaw my milk if frozen in your bags?

      When thawing your milk it is important to handle it as gently as possible to preserve all the valuable nutrients. If the bags have been stored flat they will take less time to thaw. Breastmilk frozen in our bags can be thawed in the refrigerator or at room temperature. You may also place the sealed bag in a bowl of warm tap water but never use extremely hot or boiling water.
    • Can I microwave my milk while it is in your bags?

      No, microwaving is never recommended for breastmilk as it destroys valuable nutrients and vitamins in the breastmilk. Additionally, it can create dangerous “hot spots” that could burn your baby when feeding.
