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 devices 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.

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.

Foot function

Since they will surely go to the refrigerator or freezer, the fact that they can sustain themselves without having to put them in 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.

Ready freezer

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.
