lansinoh milk storage bag

Each Lansinoh breast milk storage bag holds 6 ounces of milk.

Lansinoh breast milk storage bags are sold in several package counts, commonly 25-, 50-, and 100-count boxes.

The bags include a double-zipper seal, reinforced double-sealed side seams, and a tamper-evident tear-away top to help prevent leaks.

They are designed to freeze flat for compact storage and use a fast freeze/thaw approach intended to promote faster, more uniform thawing.

Lansinoh bags are designed for direct pumping with Lansinoh pumps and are compatible with most major pump brands when used with a pump‑into‑bag adapter (sold separately). Some reviews also note included adapters in certain cases.

Their lay-flat design freezes flatter for more compact freezer storage; they can also stand in the fridge for compact storage or be poured into bottles.

The bags are presterilized and feature a tamper-evident, fully sealed tear-away top, reinforced seams, and a double zipper to help prevent contamination or tampering.
