Milkies “No-Break, No-Leak” Breast Milk Storage Bags
We created our Milkies Breast Milk Storage Bags with reinforced sides so the bag won’t break in the freezer, and a double zipper closure so your milk won’t leak out. Milkies Storage Bags also stand up so you can easily pour your milk into them without spilling a drop.
Milkies Breast Milk Storage Bags are easy to use. The bags are pre-sterilized and ready to be filled with milk right out of the box. To fill your bag, begin by writing your name, date and number of ounces on the bag label. Open the zippers and begin pouring your milk into the bag. The bag will stand up after 1-2 ounces have been poured.
Match up the zippers and push them together along the length of the bag to be sure the bag is closed tightly. Next, place your bag in the refrigerator, or for longer-term storage, place the bag in the freezer and lay flat to freeze. The breast storage guidelines written on every bag make it easy for caregivers to handle the milk in the best possible way.

These bags are really good. They hold quite a bit a milk and are thick. They have never leaked for me. I would definately recommend.

Decent bags, Impression is meh. Hard to write on the label. You must use a sharpie. Pens won’t even write on it.

These bags do not have a horrible plastic smell! I was mortified when I recently began closely inspecting my almost three month supply of frozen milk in preparation for my baby to start daycare to find that the other bags I was using smelled awful like plastic and left the milk smelling like plastic as well. I began searching for a different brand that did not have this awful smell as it seems to be a common issue.These bags are also a bit more durable than some other brands that tend to not have that plastic smell and the closure is a bit easier to seal. The only downside is it seems there is only a 50 pack available, but I will continue to purchase these.

I’ve tried a lot of brands of breast milk storage bags; momcozy, medela, lansinoh, and now Milkies. These are the easiest to seal, way better than any of the other brands. Another bonus is that they fit in the milkies storage container, unlike medela. They have breast milk storage requirements printed on each bag, which is handy information to have. The perforated top is easy to remove. The top has a space to write your name, volume, and date. There is no space to write the time, like lansinoh bags. There is also no temperature indicator like the momcozy bags, if that’s important to you. Overall, the ease of sealing these and that they fit perfectly in my milkies storage container makes these my new favorite bags.

These are nice strong bags, they are a bit difficult to pour into but a flange used as a funnel (especially a longer one) works well. The tabs at the top do curl which makes pouring sometimes difficult so I just cut off at the zipper. I can fit 8 bags of 7 oz in a gallon zip lock(it’s a snug fit and they need to be completely flat) and I fit 7 bags of 7 oz in the milkies freezer container, these also fit in first years freezer container (I store in 4 oz) I like them for the most part they work but are on the more pricey side but i never have to worry about one leaking or bursting.

These milk freezer storage bags have worked very well for me. I highly recommend them!!For anyone wanting advice about storing breast milk, here are the other items I've used that have served me very well:- I freeze my milk in these 1oz TRAYS ( which in my opinion are a genius product!!! I highly recommend them for anyone creating a stash of frozen pumped breast milk, as the 1oz serving size is perfect so you can defrost only exactly as much as you need, and the frozen bars are so easy to store.- I purchased these TONGS ( for transferring the frozen bars from the tray into storage bags. First I'd dislodge each bar out of its mold by pushing on the bottom of the tray and letting the bars fall into the tray lid. Then I'd use these tongs to pick up each bar and place them in a storage bag.- I bought 3 of these FREEZER STORAGE ORGANIZERS ( to stack my storage bags neatly in my freezer & make it easy to know which bars to defrost first.Best of luck to all you mamas out there building up a freezer stash!!

These Milkies bags are pretty good. Other brands are notorious for leaking or busting after freezing. So far, I’ve not had a single bag break on me.These are easy to seal, stand up on their own with at least one ounce in them, and the label is at the top where you can write the date / ounces. I never knew that you should label these milk bags only on an area where the permanent marker won’t leach onto the milk. *Lots of marker brands are nontoxic these days, but better safe than sorry.

These are some of my favorite breast milk storage bags. They are easy to open and pour into, and lay flat to freeze. My biggest peeve with bags is when the top doesn't open well and the milk catches it and spills all over or gets stuck in the "zip". I pump regularly and am a milk donor, so I have become very finicky about the bags we use because we go through them FAST, and these are up there with Lansinoh as some of the best in my opinion. It is also very nice that it has storage guidelines printed right there on each bag so we all know exactly how to handle the milk safely and to keep it at its best quality. Price is right, too.
