LansinohBreastmilk Storage Bags, 100 Count, Baby Essentials, Fast Freeze & Thaw Breast Milk Bags for Baby Bottle Feeding, Superior Strength & Stretch, 6 Ounce

These breast milk storage bags have been a total lifesaver during my pumping journey. They’re super easy to use, with a wide opening that makes pouring in milk mess-free. The double zipper seal gives me peace of mind that nothing’s leaking, even when stored flat in the freezer. They are perfect for the "brick" storage concept as well.I also love how durable they feel—no flimsy plastic here. The measurements on the bag are clear, and there’s a space to write the date and amount, which makes organizing a freezer stash so much easier. Personally, I like the clear plastic color so I can see any air bubbles or freezing issues.Overall, great quality, easy to store, and a must-have for any breastfeeding or pumping mom. Highly recommend!

After discovering that Madela bags can make your milk smell and taste rancid, I switched. But, I also did a little comparison work:Lansinoh bags can hold up to 6 ounces of breast milk.Medela bags can hold up to 5 ounces of breast milk.Lansinoh: On the simplest level, the Lansinoh bag is easier to open and pour milk into than the Medela bag. The reason I find it easier is because of the material the bag is made out of and the bag is more pliable. You open the bag by removing a small strip that is perforated on the top. There are two seals on these bags, which is a huge plus. It's a comfort in preventing leaks.The reason why Lansinoh wins the freezing process is because they lay flat very well. I've found that when laid flat, the bag freezes into a solid rectangle of milk that is consistent in thickness. It is also easy to "stack" once frozen which is very helpful for organizing. It's also important to squeeze all the air out of the bag which is much easier to do since there is not a large plastic section at the top, like in the Medela bags.Medela: The Medela bags have the ability to be attached directly to a pump. As a result, there is a large plastic area on the top of the bag that is perforated. This makes these bags a little bit more awkward to open.Lansinoh: Since these bags are fantastic for the freezing process, they are easier to thaw because they are consistently the same thickness. They look like a perfect rectangle of frozen milk. Or you can freeze the bag standing up. My husband loves how easy it is to thaw these out. Way easier than Medela.Medela: Bag leaks when you thaw it and sometimes they leak in the freezer (which really is a mess). This is because there is only one seal instead of the double seal on the Lansinoh bags.

The storage capacity is great. They have never ripped or torn on me, very sturdy and easy to open and close.

These bags work well. I’ve used them with both of my children. I haven’t had any problems with them leaking this time around, the first time, I did have a couple leak. The bag is fairly thick, and easy to use. They store quite a bit of milk and the design leave some room at the top to allow the air to escape so you can lay them flat for the freezer.

These are great for breastfeeding Mamas. The quality if the bags are amazing. It is easy to fill and does notleak. It is easy to warm up the frozen milk too

Never got to use these as I never produced enough. But from what I could tell, you get what you paid for. Bags themselves seem pretty durable & could hold fluid that could be frozen if need be. Price is not that bad for the amount you are getting. Clear in color. Decent thickness. And a normal size for a breast milk baggie.

These are good bags, but I’ve noticed a few would leak once I thawed them. I do love how easy they zip together and have double the durability. They also store nicely, I lay mine so they are flat. They are easy to open but still lock the goods in safely. The plastic is kinda thin, which is why I think they leak (they leak in the corners of the bottom) overall, they are good bags and do the job, with the exception of a few that leak.

I use these every day! I have used this brand for all three of my babies and feel like they hold up the best! They store 6 oz but honestly, 5 oz is perfect. 6 oz it gets a little hard to squeeze all the air out to lay flat. It’s supper easy to open. The double zip makes it sure that the milk stays in. The bags are thick enough that they are sturdy. The bags can stand up if you open it enough when pouring in the milk. I love that you can document everything on the bag. These are perfect for pumping mamas!
