Lansinoh Breastmilk Storage Bags 100 Count

These Lansinoh breastmilk storage bags come in a 100-count pack of 6-ounce capacity, designed for parents who need reliable freezer-safe milk storage. The bags are made from low-density polyethylene without BPA or BPS and arrive pre-sterilised for immediate use. They suit families building a frozen milk supply for bottle feeding.

Simple pour-and-seal use with pump adapter option

Each bag features a tamper-evident tear-away top and a double zipper that seals securely after filling. You can pump directly into the bag using a Lansinoh pump or most major brands with a separate pump-into-bag adapter. The flat-lay design freezes quickly and stacks neatly, though overfilling past the 6-ounce mark can stress the seams during expansion.

Check pump compatibility

Verify that your breast pump brand works with the Lansinoh adapter if you plan to pump straight into the bag. Ensure your freezer has enough flat surface area to lay the bags down while they freeze solid. The bags stand upright once frozen, but they need initial horizontal space for the fast-freeze design to work properly.

Questions about this item

How can I confirm the Lansinoh bags seal properly after I fill and freeze them?

The double zipper and reinforced double-sealed seams on the sides and bottom create a secure closure; a properly sealed bag will lay flat in the freezer without leaking when thawed.

What comes in the box and what must I purchase separately to pump directly into the bags?

The package contains 100 presterilised 6 oz Lansinoh breastmilk storage bags; a pump-into-bag adapter for direct pumping is sold separately.

Which capacity should I choose if I want the standard size that fits most pump adapters and freezes flat?

The 6 oz bags are the standard capacity designed for fast, flat freezing and compatibility with most major breast pump brands via an adapter.
