Durable and Thick, Easy to Use, 6 oz Max Capacity
Awesome storage bags! The plastic is thick and durable. Each bag is sealed and a little piece of plastic needs to be ripped off just prior to use. This keeps these bags clean and free from any contaminates. They fit 6 oz in each bag. The bag is clear and the fill lines are easy to see. The bottom opens up as you are filling to stand upright which is very helpful. It is easy to get the air out of the bag and the double ziploc makes it easy to seal shut. I have never experienced any leaking. The tab to write information is on the top of the bag, which is great if you forget to write on it prior to filling. There is a spot for date, time, and amount. These bags freeze flat and make it easy to defrost. I love these bags and will continue to purchase!

Best breastmilk storage bags I’ve used
I’ve tried a few different breast milk storage bag brands, and in my experience, Lansinoh has been the best quality by far. They’re thick, durable and freeze really well. Across both of my sons, I’ve had only a few bags ever break — which is amazing compared to other brands I’ve tried. They freeze flat, which is great for storage capacity in the freezer and makes thawing much quicker. I also appreciate that they’re BPA-free and have the tear-away tops so you know the bag is completely sealed before and overall very easy to use. While I normally don’t pump directly into bags, these are designed for that option if you prefer — just keep in mind you may need an adapter if you’re not using a Lansinoh pump. I go through bags quickly, so I love that you can buy a 200-count box to cut down on constant reordering. The price is affordable too, especially for the quality. Highly recommend these for pumping mamas!

Reliable, easy to store
These are the most reliable bags I’ve found for breastmilk storage. I’ve never had a leak, they hold the most about of milk, freeze flat for ease of storage, and are thick plastic. They fit great into gallon size bags in the freezer and are very easy to use and keep track of the date you store your milk

Great Storage Bags
These work be a great to store all of our extra breastmilk! We’ve stored over 150 bags, and none of them have leaked. The seal is very strong and they’re easy to use. They’ll even stand up leaning on something which helps with the milk pouring process. It’s also very easy to pour out of the corners so appreciate that design. These bags are nice and compact for easy freezer storage.

Reliable and leak resistant
These bags feel sturdy and trustworthy for freezing and storing milk. The seal closes well and the bags stand up nicely when filling. They freeze flat and make organizing the freezer much easier. Great staple if you pump regularly.

Reliable and durable — my go-to storage bags!
These Lansinoh breast milk storage bags are some of my absolute favorites! They’re nice and thick, hold a great amount of milk, and freeze beautifully without any leaks or tears. I’ve never had one rip, even after being stored flat and stacked in the freezer. They’re also super easy to label, which makes organizing my stash a breeze. Most importantly, I completely trust them to safely store my precious liquid gold. Highly recommend to any pumping mom!

Slim but LEAKS
I loved how slim the bags were in the freezer when milk was frozen flat. However, about 75% of the bags I thawed leaked.

Making my life easier
I recently purchased the Lansinoh Breastmilk Storage Bags, and I have to say, they have made my life a lot easier as a new mom! The 200 count value pack is really convenient, especially when you're pumping frequently. Each bag holds 6 ounces, which is a perfect size for feeding. What I appreciate the most is how strong and durable these bags are. I’ve had issues with leaks in the past from other brands, but I haven't encountered any problems with Lansinoh. The double-seal design really seems to do the trick. Plus, they freeze and thaw quickly without any issues, maintaining the quality of the milk. The markings on the bags are super helpful for keeping track of dates and amounts, making organizing my stash a breeze. Overall, these bags have been a reliable addition to my baby feeding routine, and I would definitely recommend them to fellow parents looking for good quality storage options.

Ces sachets de conservation pour le lait maternel représentent pour moi le meilleur produit de ce type sur le marché: solide, de grande contenance et sans bisphénol A. Les seuls avec lesquels je n'ai jamais eu d'accident, pas de déchirure, pas de sac renversé, la matière plastique est top et prévient ce type d'accident. Par ailleurs ils sont vendus par paquet de 50 et à un prix plus intéressant que ceux des autres marques. Je les recommande.

Muy comodo el doble cierre y el espacio para marcarlas. Se pueden almacenar de pie o apiladas por lo que ahorras mucho espacio en el congelador y quedant muy bien puestas.
