When it comes to storing breast milk, you’ll want to use a storage bag that is leak-proof and durable. The best bags will be made of a thick material without BPA, have double zipper seals, lay flat for freezer-friendly storage, and feature space for labeling and volume measurements. They should also be pre-sterilized and ready to use.

They are made from a durable material, have a double-zipper seal to prevent leaks and bursts, and lie flat for freezer-friendly storage. They are also self-standing and have a large write-on area to help track dates. Plus, they come with a resealable transport pouch to keep unused bags clean and organized.
The Momcozy Silicone Milk Storage Bags (view at Amazon) are another good option if you’re an exclusive pumper or want to save money in the long run. They are a bit pricier than some single-use plastic options, but thousands of women say they’re worth it. In our testing, they were the most leak-proof and sturdy of the silicone bags we tested, and they are dishwasher-safe for easy cleaning. They also hold up to 8 ounces, which is ideal for those who pump larger quantities. If you aren’t an exclusive pumper, you can also use them for other food or baby formula later on.
