Lansinoh breastmilk storage bags are the #1 selling milk bags for breastfeeding in the US. Lansinoh milk storage bags are ideal for storing and freezing precious breastmilk. Breast milk bag storage can take place in the fridge or freezer.

You can pump directly into the bags using a Lansinoh pump. If you have another brand of pump, you can attach pump adapters to the expression set and pump directly into bags. Lansinoh pump adapters are included.

Lansinoh milk storage bags come pre-sterilized and have a patented double Click ‘n’ Secure seal to prevent leakage. With reinforced side seals and a double-sealed gusset, Lansinoh breast milk storage bags are the strongest available. BPA and BPS free.

IMPORTANT! Ensure your Lansinoh Breastmilk Storage Bags have white and purple flowers and a white line above the logo. If your bags do not have this design, it is not compatible with pumping directly into the bag. For optimum performance, remove the excess air from the bag, verify that the bag is not overfilled, zipper close the top making sure it is sealed all the way to the ends, and lay flat to freeze.
