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!

They do the job!
I have found these to be the best breastmilk storage bags. They are easy to use, not super expensive, & freeze relatively flat.

Best bags ever
These are the only bags that don’t leak. I sell my breastmilk and every time I switch brands, I get complaints about leaking. Lansinoh has never let me down and I love how flat they freeze with 6oz in the bag. Super durable during defrost and are thick enough that you don’t have to worry about tearing.

Very reliable storage bags. They seal well, do not leak, and are easy to label and store. The material feels strong and durable. I’ve used them many times and feel confident storing breast milk with these bags.

Much Better Than Medela Bags
I used the Medela bags when I first started pumping. So you know, I pumped for a year with my first child and have been pumping three months so far with my second so I have a lot of experience storing milk. Here are the issues I had with them: - Medela bags only hold 5 ounces and will not close properly if more is added; - Medela plastic is firmer which I didn't like; - Medela bags only have one seal and it's not dependable. The milk in some of the fuller bags (4-5 ounces) I put in the freezer expanded and the seal came apart and the milk spilled out!! I lost many bottles of milk using these bags; and, - Medela bags ounce measurement lines aren't accurate (at least from my experience. Why I love the Lanisoh bags: - Lanisoh holds 6 ounces or more of milk. It is riskier to put more milk in but I have put 7-8 ounces in many times and even frozen it and haven't had any issues. - Lanisoh is made of softer plastic which I love for two reasons. One, you can more easily get the air out of the bag and seal it. Two, when the milk chills the fat of the milk rises to the top and also tends to cling to the sides of the bag. What I do to mix the fat back in is take my finger nail on the OUTSIDE of the bag and gently scrape the fat into the rest of the milk The soft plastic makes this easy to do. - Lanisoh has two seals and they work! I have even held a full six ounce bag upside down for a couple seconds and it didn't leak at all. I have frozen 100+ of these bags and never lost any milk for any reason other than that it was too old : ) Only reason I gave these bags 4 instead of 5 stars is that I can't easily pump straight into the bag like you can with the Medela ones. However, I have taken the medela bag pump attachments and pushed the sides of the Lanisoh bags onto the attachments so they hung like the Medela bags. It does work but it is not as convienent and not a dependable way to pump. Instead, I usually pump into Medela bottles and pour the milk into the bags. Some reviewers have had issues with these bags which is unfortunate because I have used upwards of 200+ of these bags in the fridge, freezer, and travelling and have not had one singe issue.

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.

This was the first BM storage bag that I tried and I thought all brands must be the same.. Boy, was I wrong! I tries another brand (bcz I urgently needed next day delivery which Lansinoh didn't have then). That was my worst mistake! Anyway, I never faced any issue with Lansinoh bags.. they r very easy to use and have never leaked. The price is on the higher side but now I know why! There is a big difference in this brand and others! Going to order again
