Product Description
Pumping breastmilk is a vital function for new mothers. Keeping the breastmilk safe and ready to store for future use helps to keep your baby healthy. This is why Medela has created these double-zipper and hygienically sealed breastmilk ready to use storage bags. The Medela Breast Milk Storage Bags have been hygienically pre-sealed with durable material and double-zipper protection to prevent leaking. These bags safely store breastmilk in the freezer, fridge, or when traveling. These ready to use breastmilk storage bags are constructed from a durable, double-layer material with a built-in double zipper seal to keep your breastmilk safely stored in the fridge or freezer.
The Medela breastmilk storage bags have been designed to be self-standing and come with a large write-on area. This allows you to document the date and other vital information for safer storage and use. Also, the Medela Breast Milk large 6-ounce Storage Bags have been designed to lay flat for space-saving storage. This unique feature allows quick thawing of frozen milk when your baby is hungry. To help you keep these breastmilk storage bags clean and organized, we’ve added a bonus resealable transport pouch that keeps unused bags organized and clean.
Medela offers two types of storage bags to fit your lifestyle. Our new breast milk storage bags are for moms looking for save only bags and who don't need or want to pump directly into the bag, while our Pump & Save bags are designed for moms who want the added convenience of pumping directly into the bag. With either choice, we've got you covered. Medela’s primary focus is on helping moms to successfully breastfeed their babies for as long as they choose. Meeting this goal responsibly is at the heart of everything we do.

- Reviewed in the United States on September 6, 2024Size: 200 CountUnit Count: 200.0Verified PurchaseMy baby is 3 months old and I'll be returning to work soon, I've been using these bags to store any additional milk I have for later. These bags have been great! They are durable and withstand freezing and unfreezing without leaking or compromising your milk. They hold approximately 6oz, but you need to fully unfold the bottom of the bag for it to read 6oz on the labeled scale. I normally freeze my bags laying flat for easier storage so I measure my milk with a bottle and then just pour in instead of using the bag for measurements. I like that they have a large area for labeling and the labeled area does not smear or run when using a marker. I tried several other products before this one and enjoy this is the most. These bags are as advertised and are a great value for your money.

- Reviewed in the United States on February 16, 2025Size: 100 CountUnit Count: 100.0Verified PurchaseThese are my favorite milk bags because they’re thick, compact, and stack well when frozen. I’ve tried others before but these are definitely my favorite.
- Reviewed in the United States on September 19, 2018Size: 100 CountUnit Count: 100.0Verified PurchaseI have purchased several breastmilk storage bags from Medela to Avent to Lansinoh to NUK. I found that I really like Medela bags the best follows by Lansinoh.
I remember when I was initially was shopping breastmilk storage bags, I wanted to see pictures of how the bags look when they held unfrozen milk and how they look when frozen, so I've provided a picture to compare several brands. I found that Medela bags are superior to the rest, the quality of the bag is high quality and none of the other brands (lansinoh, NUK, or Avent) can compare. As you can see in my picture, it stands the best though it does not lay the flattest for storage. Initially storing the milk in a freezer was huge concern to me on how flat the bag got but this it not too much of a concern anymore as I had to purchase a deep freeze just to store breast milk (thanks to the help of Mother's milk tea, Blessed Thristle and Fenugreek supplements when my supplied went low on few occassions because my pump malfunctioned and stopped working). I find that Medela bags are the easiest to pour out, (I initially would pump at work and pour into bags and then when I went home would pour it from the bags to bottles to store in the fridge for the near-future feedings) because of the sturdiness of the bag, I had more control and it was not flimsy or bent when and where I did not want it to. I was able to shape the top of the bag to make pouring the milk out easier.
I do not recommend pumping directly into the bags. I've attempted to do this on several occasions and was very frustrated with the process, I just decided to use bottles instead. I tried this method because I felt it was tedious to pump in the bottle and then pour it in the bag to go home and pour it out into another bottle for future feedings. However, the process was too cumbersome for me and now I simple just pump in a bottle which I refrigerate until I leave work and then pour it into my baby's feeding bottles (as you can see I have bottles I use just for pumping different from his feeding bottles though I could use these bottles for feeding as well, I'm just limited to slender or shorter larger bottles like the Medela 8oz or Gerber tall bottles I use Medela caps on and didn't want to buy more).
Overall, these are my absolute favorite breastmilk storage bags though I do wish they laid flatter but then again I tend to store 6-8 oz in a bag (yes, I know I shouldn't go over 6oz but I do). I highly recommend them over the others with the lansinoh as my second choice. As you can see in the images which are all holding 6 oz of unfrozen milk, both the Medela and lansinoh sits upright well while the lansinoh does lay flatter than the Medela bags.

Size: 100 CountUnit Count: 100.0Verified PurchaseLas bolsitas son perfectas para guardar la leche materna. Un tip es cerrarlas bien y ponerlas acostadas en el congelador y una vez congeladas ponerlas parada en un tupper para que te quepan más. Excelente producto.

5.0 out of 5 stars Excelente producto, mejor paquete relación precio por unidad
Size: 100 CountUnit Count: 100.0Verified PurchaseMuy buenas bolsas, súper fáciles de usar. Se abren sin ningún problema y sellan perfecto, ya hemos usado más de la mitad de las bolsas de este paquete y jamás hemos tenido una fuga, ni un problema. El espacio para etiquetarlas es suficiente. Dudamos si necesitaríamos tantas (mi bebé solamente toma leche materna), y en 8 semanas aproximadamente que las hemos usado, ya pasamos a la bolsa número 54, por lo que me parece el paquete de mejor opción por el costo de cada bolsa, especialmente porque No son reutilizables. La usas y debes tirarla. No tienen capacidad de 180 como dice en la bolsa, algo falla ahí, pero cuando saco 150 en mi sacaleche (de la misma marca) al poner la leche en la bolsa llega hasta la marca de 180. La recomendación es no llenar demás la bolsa o puede explotar al congelarse, pero yo he puesto hasta 160 ml sin problema.

5.0 out of 5 stars Great for creating a backup supply of breastmilk in the freezer.
Size: 100 CountUnit Count: 100.0Verified PurchaseThese Medela breastmilk bags are perfect for storing breastmilk. They have a very strong ziplock that will not open in the freezer once sealed properly. On the top of each bag is a place to write down (with a permanent marker preferably) the date the milk was frozen as well as the amount of milk in the bag. I would recommend not filling the bag to the top because this way you can lay the bag flat to freeze ensuring that the least amount of space is taken in your freezer. These bags are also great because the bottom of the bag expands to allow them to stand if you need some stability while filling the bag. Another thing I noticed is that the milk contained inside stays in perfect quality especially if you ensure proper rotation in the freezer. My baby never refused defrosted milk. These bags can be easily submerged into warm water to defrost and warm the milk. I have found that adding 3-4 ounces of breastmilk works the best for freezing and also is a good amount to defrost for feeds.
