What Are Breast Milk Storage Bags?

There are reasons why you may way to store your breast milk. It might be from overproduction of milk, or you are unable to breastfeed your newborn for personal reasons correctly. Either way, it's important to find the right way to store this important food for your baby. That's where the breast milk storage bag comes along.

These are bags marked with measurement lines and the tight seals to store your breast milk without it leaking out or getting contaminated by forms of bacteria. These bags are usually disposable and come with the features needed to keep your breast milk safe to consume during your baby's next feeding session.

It's also beneficial for those whose breast milk flow isn't strong enough when it's time to feed their baby.

Storage Bags vs. Bottles

Before anything else, you might be wondering about the difference these storage bags have and the baby bottles parents use when storing milk.

  • One main difference (and advantage) storage bags have over bottles is the fact that they're cheaper. A pack of 50 storage bags is already two to three bottles! Also, storage bags are easier to thaw as compared to thawing milk from bottles.
  • Storage bags are the best for storing milk since they take up less space. But bottles are much more durable and convenient since you can reuse it for storing more milk and can also attach to breast pumps to efficiently add and store your milk. But fortunately, there are now storage bags that can connect to some breast pumps as well!
  • If you want to save time from cleanups and need to do store more than a few bottles of milk, then storage bags are the best choice.

Benefits of Using Breast Milk Storage Bags?

Why bother using storage bags in the first place? Here are the pros when using these bags:


Using storage bags are very easy to use since you only need to fill it up and seal them properly. They are also disposable and save you time cleaning it up! Also, it thaws out quicker than any other bottle because of its plastic material.


As compared to using bottles or other storage methods, these bags are more affordable, but with the similar features when securing your breast milk.

While they are only meant to be used once, you can purchase multiple bags at very affordable prices. Most packs can last for a few weeks to months!


No need to worry about looking for extra space to store milk, because plastic bags take up less space and have the leak-proof feature to avoid it from spilling.

Tips on Storing Breast Milk

How can you correctly fill the storage bag with your breast milk? Here are some tips to follow:

  • Make sure that your hands are clean and sterilized before handling your breast milk and storage bags. Wash your hands before and after doing so.
  • Before sealing the bag, make sure that you squeeze out any excess air, leaving a bit of open space and pressing the bag down until all air is gone. Then seal it tightly.
  • After properly filling your breast milk into the storage bags, label the date and time you produced the breast milk, as well as when you filled the bags. That way, you know until when the milk can be consumed. Refrigerated milk would last for about three to eight days. Milk stored in the freezer lasts for six months.
  • Freeze milk at the back of the freezer, away from the door or sides. Also, do NOT refreeze the milk. It must be consumed within a day of thawing it in the fridge.

Now that you know everything about these storage bags, how can you tell which one is the best to buy? Here are some tips and factors to consider when purchasing these storage bags for you and your newborn:


​Make sure that the bags you purchase are made out of the strong material free from any chemicals. This will help keep the milk in place without worry of contamination or leaks.


​How big do you need each bag to be? Get the adequately sized bags to fit your freezer and the amount of milk you produce for your newborn's next feeding. The standard size would be around six ounces, while you can find bigger bags that can take up to eight ounces for those who need more volume.


​While you'll need to focus on the customer reputation and purchase from trusted brands, you'll also want to focus on your budget. Remember not to scrimp and buy cheap quality, but that doesn't mean you should break the bank getting the most expensive ones! Set a reasonable budget and start your search from there.
