What Are Breast Milk Storage Bags?

best breast milk storage bags

First of all, they are beneficial when a mother has too much milk; when the baby had enough, these handy bags are used for storing the milk for later use. Next, there’s the milking and baby’s hunger synchronization, which can often be unbalanced.

The problem of breastfeeding in public is another concern of which many debates have happened. Breast milk storage bags are very convenient in this situation. Whenever you’re out for a walk with your beloved child, you can carry a breast milk storage bag and have it ready for a quick feed without attracting unwanted attention.


Furthermore, there is the breast milk storing and spoiling issue, which is solved with breast milk storage bags very efficiently. As it is well known, this milk is sensitive and not as durable as other types, so it’s the best to store it in the fridge as soon as possible if you’re not going to feed it to the baby. These bags are specially designed to keep the freshness and all the nutrients of the breast milk for a significant time.

How to Use Breast Milk Storage Bags?


Using these bags usually involves a breast pump of some sort, which is used to draw the liquid into a sterilized bottle. The bottle is usually connected with a bag by a small pipe. The milk is transferred to the bag by that same pump, or by simple tilting of the bottle. The bags usually have a hermetic sealer or a mechanism that protects the milk, among other features.

Storing the milk in the breast milk storage bags is quite simple, you only need to care about the storage times. For the milk to retain its freshness and nutritional values, you should keep it stored for seven hours on the room temperature, around five days in the fridge, and around 12 months in the freezer.

What to Look for In Breast Milk Bags?


There are several factors to consider when buying breast milk storage bags, and here we’re going to categorize them by importance:



Firstly you should consider the product’s configuration; does it come with a breast pump and a bottle, or the package contains only breast milk storage bags. Depending on your current equipment, you should aim for a complete solution or a breast milk storage bags refill. Having 100% compatible breast milk storage bags and a pump & bottle, all from the same manufacturer, ensures perfect functioning and performance and enables direct pouring into the bag.

If you have a bottle/pump already, you should look for products that are compatible with your equipment, simply because of the possible issues that incompatible bags might bring.


Pump compatibility and seals, safety standards

If you do have your own pump and bottle, make sure to inspect the bag’s compatibility with the pump and bottle. You don’t want to get a bag which isn’t compatible with your equipment – that will cause leaks and problems while connecting.

While speaking of leaks, check the bag’s sealing; this feature will keep the milk inside when handling the bag and protect it from the external damage. High ratings on seals and features like double zippers are the way to go. Furthermore, check if the bag’s safety standard regulations.


Size and measuring units

The size of the bag directly determines the amount of milk it will hold. The possible capacity can go from 3oz to 7oz. Depending on how much milk you produce daily, you might need larger bags.

Furthermore, there should be a measurement system of some sort on the bag, simply because you should know how much milk you’re pouring inside. Knowing this can be quite useful.



The thickness and overall durability of the bag usually aren’t stated on the information online, but many breast milk storage bags reviews can be a big help here.


Pre-sterilized or not

When you shop for breast milk storage bags, you need to pay attention to this little information. Many bags do come pre-sterilized, but there are some that don’t. Make sure to check the product’s description, and if it lacks this information, you may want to contact the seller or ditch the product.



The price comes as one of the important factors since it determines the quality and number of bags you will get in a package. Make decisions depending on your needs and budget.

Coming from one of the top manufacturers in the market, Mommy’s Precious, these breast milk storage bags have a lot of reputation to defend and justify. Even though not the strongest, this brand is quite popular because of the quality products and decent prices.

The manufacturer advertises them as high leak proofing, self-standing, and highest safety breast milk storage bags on the market. They consist of standardized BPA-free, Phthalate-free, and Latex-free material. The durability is on par with the standards, and the self-standing feature is neat and functions well.

The bags come pre-sterilized and labeled with accurate measurement lines. Alongside the cute giraffes design, a nice bonus to this measurement system are the writeable tabs, which you can use to add details like date & time on the bag, making sure to use the milk in its finest state on time. Bags are refrigerator-ready out of the box.

The seals on the bags are quite strong, designed in a straight line using perforation technology for quick closing and opening. The double zip lock is added on top of that for maximum security, but unfortunately, it doesn’t open the already closed bag quickly, especially after freezing.

Sized at 3.9 x 0.1 x 8.3 inches, the bags come with 8oz capacity (250 milliliters), and you get 110 bags in the package, for a decent price.

Things I liked

  • Design & measurement system + writable tabs.
  • Durability, protection of the milk.
  • Self-standing feature.

Things I didn’t like

  • Opening can be quite a nuisance, especially after freezing.
Medela Breast Milk Feeding Gift Set

Here we have an all-around option for moms-to-be and ones who are starting to stack up with equipment for the baby. Medela is among the top manufacturers on the market, and a reputable name in the industry. Their products are aimed to provide the complete experience to customers, and they do their best to provide as much features and functions as possible.

This set contains an abundance of precious items for a mom-to-be. From the bottles, pumps, nipples, collars, slow-flow nipples… Everything is there. Here are the exact contents of the package:

  • 3 x 5oz bottles with bonus equipment.
  • 20 x 5oz / 150ml breastmilk bags.
  • 2 x connectors.
  • 6 x 80ml (2.7oz) bottles with lids.

Firstly, with this set, you get the perfect, 100% compatibility and flawless functioning. No spilling or problems connecting anything will happen to you. The bottles are made of high-quality polypropylene, everything in the set is BPA-free, and provides incredible versatility. You can stack on breast milk in both bottles and bags, and organize the feeding based on your schedule.

The nipples included in the package are soft and have good milk flow, so your infant will love them. The bags themselves are on par with the rest of the package, providing enough space for 150ml or 5oz of breast milk.

They have writable labels on top and have a double measuring system painted on top. Opening and closing them is slightly better compared with the previous product, but still not as good as I’d like. One more thing – the set would be perfect as a gift if it would include a pump, but that’s not the case.

Things I liked

  • Versatility.
  • Compatibility.
  • Durability.

Things I didn’t like

  • Not a complete starter kit.
  • A bit awkward smell from the bottles out of the box.
Nurture Right 6oz Breastmilk Storage Bags

Currently in the process of becoming the best distributor of child care products, Nurture Right attracts customers with attractive designs, quality products, a lot of versatility & compatibility with other products, and affordable prices. Their breastmilk storage bags are advertised as of high-quality, meeting all security standards, having beautiful design and functionality, and all that for a reasonable price. Let’s check them out:

The bags are made from durable, thick material, and assembled using high-quality processes. That impression comes from the interior of the bags, which doesn’t have that plastic smell that you may encounter using similar bags. They come pre-sterilized, BPA, Phthalate, and Latex free, and sealed with a leak-proof double zip seal. The bags can house 6oz of milk comfortably, without leakages or spills.

One downside I encountered with these is the narrow opening on the bags, thanks to the strong double zip seals. Don’t get me wrong, double zip seals are great, but you might encounter difficulties pouring the milk. Self-standing bottom design helps with this issue, though. Seals are excellent, with no leakages, but the opening is, again, a bit problematic.

Measurements and writable tabs are a big advantage on these bags; you’ll have enough space to write down every info you’ll need. The price is a bit higher, and you get 100 bags in the package, which is a decent deal, but you can’t help but notice that there are better on the market.

Things I liked

  • Design & measurements, writable tabs.
  • Durability.

Things I didn’t like

  • Opening.
  • Narrow at the top – not easy to pour milk in.
  • Pricey.
Kiinde Breast Milk Storage Twist Pouch
(Via: amazon.com)

Here we have a modern and efficient solution for the whole breastfeeding process – a single pouch with a twist sealer, which can be used for both milking, feeding, and storing. Quite the impressive set of features on the first glimpse. The Kiinde company is not as long on the market as other manufacturers, but their scientifically backed solutions are getting them more and more customers every day.

Their breast milk storage bags come with a unique feature – the twist technology that performs surprisingly well on the both sides of the breastfeeding process, both while milking and feeding. Furthermore, the bags are quite durable, made from quality polypropylene, and labeled with clear measurements.

There are 6 and 8oz bags available for purchase, with several buying options (20-160 pieces per package), all reasonably priced. The twist mechanism matches on any pump you can get (the special adapter is required for some pumps).

The pouches are designed to be used for direct feeding, so they collapse while the baby is sucking milk (oval nipples are included in the package), so there’s no air in the baby’s meal, eliminating colic. Kudos to Kiinde for this neat feature.

Things I liked

  • Simple and convenient to use.
  • Innovative and very efficient.
  • Removes the mess from breastfeeding.
  • Very durable.

Things I didn’t like

  • Plastic smell out of the box.
  • Pricey.

Coming from a reputable brand (started by a breastfeeding mom), these breast milk storage bags are among the best-selling products on the entire market. This speaks quite a lot about the quality, the brand, and the performance these bags deliver.

One of the biggest selling points of these bags is the pour-into-bag-directly feature. It allows you to connect your pump directly to a bag with a patented Click ‘n’ Secure seal which is advertised to prevent any leak possible. The truth is that some leaks might occur since we’re human beings and are handling bags with liquid here.

The measurement labeling is clear and spacious and accompanied with some lovely flower designs. The side seams are double reinforced and advertised as the strongest and the largest milk storage bags available on the market.

The bags come pre-sterilized, without smells, built BPS and BPA free. The bags can hold 6oz of milk comfortably, but after pouring more than 4oz, you increase the risk of spilling and leakages. There are five different buying options for you to consider (each having 50 more bags), based on your preferences.

Things I liked

  • Pre-sterilized, odorless.
  • Money/value ratio.
  • Nice measurement labeling & design.

Things I didn’t like

  • Not 100% leak free.
  • Good for storing, not for feeding or pumping.
