Storage Bag Specifications at a Glance

Breast Milk Storage Bags: Seal and Leak Protection

A storage bag is only as good as its seal. These breast milk storage bags are engineered specifically to prevent the leaks that ruin a freezer stash:

• Double zipper seal - Every one of these breast milk storage bags uses a double zipper closure, so milk stays sealed even when bags are stacked or shifted in a full freezer
• Reinforced seams - These breast milk storage bags are made with reinforced side seams designed to hold up under the pressure of a stacked freezer without splitting
• Self-standing fill design - Each bag in this pack of breast milk storage bags stands upright on its own, so you can fill it hands-free without spilling a single ounce
• Freezer-safe, space-saving shape - Once frozen, these breast milk storage bags lay flat for compact storage, then stack or stand upright to maximize freezer space

Capacity and Tracking

Keeping an organized freezer stash means knowing exactly what you have and when it was pumped. These breast milk storage bags are built for that:

• Six-ounce capacity - Each bag in this set of breast milk storage bags holds up to six ounces, matching a typical pumping session so nothing goes to waste
• Clear measurement markings - Printed ounce markings on every bag let you see exactly how much milk is stored at a glance, no separate measuring or labeling tools required
• Built-in space for labeling - A flat writing surface on each of these breast milk storage bags makes it simple to note the date and amount as you fill it
• 100 bags per pack - With 100 breast milk storage bags per pack, most moms get weeks of consistent freezer storage from a single order

Breast Milk Storage Bags: Material and Safety

• BPA-free - These breast milk storage bags are BPA-free, so nothing that touches your milk contains this common plastic additive
• Free of PVC and latex - Every bag in this pack of breast milk storage bags is also free of PVC and latex, reducing the risk of irritation or unwanted chemical exposure
• Single-use hygiene - These breast milk storage bags are intended for one-time use, which keeps every feeding as hygienic and safe as the last
• FSA/HSA eligible - These breast milk storage bags are FSA/HSA eligible, so you can use pre-tax dollars toward your freezer stash supplies

How to Use Storage Bags Safely

Most storage failures come from handling, not the bag itself. Follow these steps to protect every ounce you pump:

Don't Overfill

Fill each of these breast milk storage bags only to the marked fill line. Overfilling is the leading cause of leaks in any storage bag, because milk expands as it freezes and puts pressure on the seal and seams.

Remove Excess Air

Press out excess air before sealing your breast milk storage bags to reduce freezer burn and make stacking easier. Less air in the bag also means milk freezes flatter and thaws more evenly.

Label as You Go

Label each bag with the date and amount as you fill it, so older breast milk storage bags get used before newer ones. The flat writing surface on each bag makes this a two-second habit rather than a chore.

Freeze Flat, Store Upright

Lay breast milk storage bags flat while freezing, then store upright once solid to save freezer space. Flat-frozen bags stack cleanly and thaw faster than bags frozen in a lump.

Thaw Safely

Do not boil or microwave these breast milk storage bags. Thaw stored milk in the refrigerator or under warm running water instead. Milk stored in these bags can typically be refrigerated for up to 4 days or frozen for 6 to 12 months, depending on your freezer type.

Who Should Stock Up on These Breast Milk Storage Bags

• Moms returning to work - Want reliable breast milk storage bags to build a stash before their first week back at work
• Moms sending milk to daycare - Need breast milk storage bags that store and travel well for daycare drop-off
• Moms building a backup supply - Rely on breast milk storage bags to organize a growing NICU or backup freezer supply
• Moms who exclusively pump - Prefer breast milk storage bags with clear markings over guessing at ounces in unlabeled containers
