- Make sure that it’s freezer-safe
For more detailed information, read through our buying guide below.
Check If It’s Sterilized and BPA-Free

Unlike regular sandwich or zip lock bags, breastmilk storage bags are pre-sterilized. This is to make sure that the breastmilk will not be contaminated and is safe to drink by your baby. Since these are made of plastic, always check if the material is BPA-free.
As an additional security measure, some milk bags have safety or tamper-resistant seal - the extra piece of plastic that you need to tear off before having access to the zip feature of the milk bag. It ensures that no particle or dust enters the bag while inside the box. It also shows that no other human contact has been made.
Milk bags should be sterilized, clean, and convenient. Make sure that the milk bags are clean and dry before transferring the milk to ensure that it doesn't get contaminated.
Look for Storage Bags With Ounce Markers

Look for milk storage bags with ounce markers, so it’ll be easier to measure and track how much milk has been poured inside the bag. These volume indicators are especially helpful for moms who pump directly into breastmilk storage bags.
One of the main guidelines in storing breastmilk is to label each milk bag with the pump date and amount of milk inside. So opt for milk bags with a designated space for writing labels. This helps you monitor which milk should be consumed first.
Ounce markers and labels also make it easier to tell how much milk needs to be thawed and rewarmed for your baby’s feeding. You’ll also know which milk bag should be discarded should it reach the breastmilk storage bag expiry date.
The "first in, first out" rule applies here. And it will be very convenient for the mothers to monitor the milk that needs to be consumed first.
Select the Size of the Milk Bag Depending on the Amount of Milk You Express

A baby usually drinks around 1-4 ounces of breastmilk in a single feeding, so storing that amount per storage is a good idea. Consider that the milk will expand when it freezes and that each bag can be filled up to 3/4 only. The bag must not be too full to avoid any waste because of spilling.
You can choose between milk bags that can hold 3 oz, 4 oz, 6 oz, and 8 oz. Some have volume indicators in terms of ml, wherein one bag can safely hold 60 to 120 ml of milk. When it comes to size, the deciding factor would be the amount of milk that you can express per pumping session.
You can try 1-2 sizes at first until you become more familiar with your “usual volume,” so no plastic storage bag will be wasted. Most storage bags come in a box of 25 or 50 pieces. This can last from 2 weeks to one month, depending on how often you pump breastmilk in a day.
The sizes will depend on the amount of milk that you can express. This will be a trial and error at first, so make sure to try the small ones first instead of using the big ones immediately.
Consider Its Zip Seal and Structure

Since it'll be hard to inspect the zip seal or zipper closure of the breastmilk storage bag, check the comment section of the shop for customer feedback. Most milk bags feature a double-zipper closure or even a triple-zipper seal which ensures that they are leak-proof.
Check the structure of the milk bag as well. It's fairly easy to figure out how to store breast milk in a feeding bottle, but it'd be helpful if the bag has a wide opening. This is for easy transfer from the pump bottle as well as a spout when you need to pour the milk into the baby bottle.
The storage bag must also have reinforced sides for easy freezing and durability. The bottom area must be of high strength, too, and is anti-slip, so the bag can stand up when you're transferring milk.
Getting advice from experienced mothers will be helpful in navigating the first few months of being a mother. Make sure you do your research first before purchasing some baby things. With regard to milk bags, thorough research is a must. This is so you can maximize your purchase since they can be a bit of an investment.
Make Sure That It’s Freezer-Safe

Since unused breastmilk storage bags don't expire, it's more important to check if the bag can withstand different temperatures. It must be freezer-safe and can also be thawed when placed in warm water. The thickness of the bag will also come into play because the length of thawing and rewarming depends on its thickness.
As mentioned before, it is trial-and-error when choosing some baby products. That is why it is important to do your research. When it comes to choosing the right milk bag for you and your baby, it will still depend on how much milk you can express. If you are exclusively breastfeeding, it is helpful to check the thickness so you can gauge how many minutes you need to thaw the milk bags.
