How to Make the Best Purchasing Decision When It Comes to Breastmilk Storage Bags

Now that you’re aware of some of the best breastmilk storage bags on the market, it’s time to choose the ideal product for you. Scroll down to discover my step-by-step buying guide, detailing everything you need to know to make the most educated decision possible.


As with any child-related product, you want to be sure that the product you’re buying is safe for both you and your child. With traditional breastmilk storage bags, they were previously produced using plastics that contained BPA, PVC, phthalate and BPC chemicals.

It’s been proven countless times through studies that these chemicals are easily absorbed into children’s delicate skin and can affect their bodies in such a way that it can cause damage or, in other ways, hinder their development and growth, or their reproductive systems.

To eliminate any risk of this happening, it’s highly recommended that you choose products that have been expertly designed to be free from these chemicals.

As you can see from my selection, there is a complete range of breastmilk storage bags that go out of their way to ensure that their products do not contain these chemicals. The best way to check is by simply referring to your products packaging or product description.

Ease of Use

When you’ve got a crying baby in one hand, you’re late for work and your daily list of jobs is piling up, you don’t want to be messing around trying to figure out how to use your storage bags.

Look for bags that have been designed to be as easy to use as possible. Some good features to look for include easy-to-open bags that have dedicated pull tabs as well as gravity-assisted features that help the milk to drain down into the bag eliminating the risk of it sitting at the top.

To make things even easier, look for bags that you can directly attach your pump to. These may be more expensive, but it will save you so much time when it comes to transferring and storing your milk because you simply won’t have to do it.

It’s worth noting that some bags are truly universal whereas others are simply universal with other products in their brand’s product line, so always check the description before you buy.

Leak-Free Protection

You don’t want to spend hours every day filling up your storage bags only to realize that they’ve burst and the milk is now rendered useless. Fortunately, there is a whole range of features that can stop this happening.

The first and most obvious of which is the seal at the top of the bag. Whether you’re laying your bags flat or standing upright, if there’s a gap at the top of the bag, the chances are that the milk is going to spill out at some point. To alleviate this problem, look for bags that have leak-free zips and seals or double-seals that minimize the risk of the milk spilling out.

Some bags will also come with reinforced sides that will stop the bags from splitting once they go in the freezer. Be aware that the bags will expand slightly when freezing them so don’t fill them to the top, only to the maximum level.

The base of the bag is also very important to check. Ensure the seal around the base of each bag is tightly sealed and is strong enough that it won’t leak.

Storage Capabilities

If you’re producing a lot of milk, the chances are that you’ll have a lot of bags. Ensure the bags you purchase are able to free-stand in your freezer or lay flat, ensuring that you can maximize the storage space in your freezer.


Purchasing the right breast milk storage bags may seem like an easy task. You could simply walk into your local shop and purchase the first ones you see, but you’re then taking the risk of having a stressful and time-consuming experience.

Rather save yourself the time and the hassle by investing in a fully-featured storage bag, guaranteed to make your life easier while granting you more time to spend loving your little bundle of joy.
