For a ridiculous price, you can have 25 bags to store your milk and it will never be missing from your home again.

They can be used either in the fridge or in the freezer, although, as you may have imagined, they will last just 48 hours in the fridge, while in the freezer you can store them for a longer period of time.

One of its aspects that has conquered me personally is that it allows you to write on the outside so that you can have a multitude of factors under control, such as the day you put the milk in the freezer.

It is a BPA plastic bag that, however, is completely sterilized, in such a way that it will not give you any type of health-related problem.

The only thing that I did not like at all, is that every time you fill a bag, you will have to make sure that not a single bit of air has remained inside because otherwise, it could end up damaging the structure.

Benefits breast milk storage bags

The preservation of breast milk is perhaps the topic most touched by mothers since there are many opinions on the subject, the type of container and the storage time.

Everything must be adapted to your needs and those of your baby, at the same time as the volume of milk production you have. Storing your baby’s milk can be a great help for the father or some other family member to create bonds with the baby while you rest, take a shower, take a meal with ease, etc.

When deciding to create a milk bank, the extraction time of the milk is important, since as it is expressed, milk production is stimulated, which benefits the bank since it will grow steadily.

It also gives us peace of mind to be able to leave the baby in the care of someone else if we have to leave or return to work.

The breast milk storage bags have gained considerable popularity as they fulfil the functions of plastic or glass bottles, but they save us a lot of space, as well as being easy to use and disposable.

You will save a lot of space in the freezer, contrary to if we use bottles, being these more expensive and require specific maintenance while these bags are completely disposable, as well as being easy to transport and keep milk inside, without risk of accidents.

Breast milk bags have become the best friend of mothers who seek exclusive breastfeeding with their children, but who due to illness or work must extract it and store it for later use. Different methods can be used for the extraction and for its storage you can use bottles or bags directly, being able to connect both directly to the breast pump to avoid more work.

Before acquiring a breast milk bag we should mainly study the capacity of the same, since depending on it we will know the time and speeds to use when the breast pump is activated. It is also important that they have a space to write the extraction data, making its storage and subsequent use much easier.

Its type of closure will make it practical to store or simply to extract in a container other than the bottle, since when you use a breast milk bag you are making the process more hygienic, reducing the number of bacteria that can be found inside the bottles after its cleaning, depending on the model, can be stored in the smallest parts, with the bags you are sure that everything will be clean throughout the process.

The different scenarios after giving birth do not have to limit your commitment to breastfeeding since with the extraction and conservation of milk you give your baby all the benefits necessary for optimal development for a longer time.

How to use breast milk storage bags?

You must start by washing your hands very well before starting to pump. At the end of the process, you can open one of the bags to pour everything extracted. Use the safety zipper in the right way. Most bags have a double seal and a form that indicates how to use them and how to keep them properly sterilized. It is important that all packages are labelled with the extraction date so that you can monitor their validity and thus there are no dangers in the healthy nutrition of the child. The storage bag should be in a special area so that it does not mix or deteriorate with the food you have in the refrigerator.

How to transport breast milk storage bags?

First of all, you must guarantee good quality in the market because the cheap has its cons, and in this case, it can negatively affect the child’s health. Use one that has the property of maintaining the temperature. Once the bag has been opened, you must move it to the bottle and when you get the desired heat, you will be able to feed the baby wherever you are. Check that they are waterproof, that they seal well, and make sure that the liquid does not acquire a plastic odour, which can generate the frustrating rejection in the infant.

What to consider when choosing

Before choosing one, it is essential that you look at a series of qualities that will make your selection more accurate and you can ensure that you have the right model on hand and that it suits your needs, so before buying, it is essential that you look at these details:


This quality is measurable with the thickness of the bag. If your purpose is to store the milk to freeze it then you should make sure it does not leak. A thick bag will be more durable than a thin bag.


Generally, these bags are filled through two systems. Or you pump directly into the bag, or you do it in a bottle and then into the bag. You should go with the one you find most comfortable and practical.

It is advisable not to fill it beyond its capacity because however resistant they are if you overlap it will be more prone to leakage. You should check which of the sizes works best for you. They come in sizes of 4 ounces and 6 ounces.


You should avoid union seals or labels because they are more prone to leaks. I recommend screw caps or double zippers.

Easy to use

A bag that is not difficult to fill and that is thick and with a pouring spout will come in handy. Do not complicate your life.


Given the delicacy of the content, you must ensure much of this point. I recommend you go with a brand of remarkable reputation with all its certifications.


This refers to storage. The good is that you get everything in one. Bag and breast pump to do all the work at once.


You must make sure that they have this feature. The opposite can be an unnecessary risk to the health of the baby or a lot of complication for your lives.


Babies usually drink certain amounts of milk, so a bag in which you can measure the content is a very useful idea. So you can pour into the bottle only the amount that the child will drink.

Vertical position

Since they will surely go to the refrigerator or freezer, the fact that they can sustain themselves without having to put them in a horizontal position which carries risks of leakage. This quality is essential because you can place it in the fridge or countertop without worrying about falls and spills.

Compatible with a pump

Some bags come package all in one, but if it is not the case you must make sure that the selected one is compatible with your milk extractor pump.

Freezer frendly

Given the storage levels you have designed for these bags, the most advisable is that you decide for a group that is resistant to cold and able to get into the freezer. It will facilitate your life, storage, it will last longer and you will be calmer.

It is sold in a dispenser

This allows compact storage and undoubtedly takes away from problems and complications.
