Medela Breast Milk Storage Bags, 100 Count, Ready to Use Breastmilk Bags for Breastfeeding, Self Standing Bag, Space Saving Flat Profile, Hygienically Pre-Sealed, 6 Ounce

It is late evening, the pump session is finished, and there is milk that needs to go into the fridge or freezer before bed. This is the point where a bag that is already sealed and ready saves a step.

The pack contains 100 Medela Breast Milk Storage Bags, each holding 6 ounces, plus a resealable transport pouch for keeping unused bags together in a diaper bag or drawer. The bags arrive hygienically pre-sealed and are made from BPA free, food-grade material in a double layer, with a built-in double zipper closure. Each bag stands on its own while being filled and has a wide blank panel for writing the date and any other details. The flat profile means filled bags stack neatly rather than taking up shelf depth in the freezer.

• 100 bags, 6 ounce capacity each
• Double-layer material with double zipper seal
• Self-standing, lay-flat design with write-on area
• Bonus resealable transport pouch included

Bags are single use, so keep the transport pouch closed to store the unused ones cleanly.

When filling the bags, leaving about an inch of space at the top before sealing gives the milk room to expand during freezing without stressing the zipper. Once sealed, laying the bags flat in the freezer while the milk is still liquid lets them freeze in the thin, uniform shape that makes stacking straightforward. A bag that freezes standing upright or at an angle takes up more space and is harder to slot alongside others. The wide write-on panel is large enough to fit the date, the session time, and a volume note, which matters when rotating through a mixed stock of bags filled at different times.

These bags suit pumping parents who want to move milk from a work bag to a home freezer without transferring it to a different container, since the bag goes directly from pump output to storage. For anyone comparing storage options, the 6 ounce capacity fits a typical single pump session for most people without leaving large amounts of unused space that could introduce air. Single-use construction means there is no cleaning step between uses, which is the main practical difference from hard-sided reusable containers.
