Product Description

The NUK Breast Milk Storage Bags are very useful for lactating mothers. These self-standing milk storage bags are freezer safe so that you can save milk for your baby to be fed when you are not around. They come in an innovative design and a leak-proof double zipper seal that make the process much more efficient. The baby milk storage bags come available in 25-count, 50-count and 100-count packs, and they easily fit most disposable bottle holders. The bags can go into the freezer standing up, and the volume markings on the front allow you to see how much is in each bag. They thaw easily, making meal time quick and easy. These freezer storage bags also feature a space to write the date on the bag so that you know how old the milk is.

Helped me save 2500 OZ with ZERO leaks!

Helped me save 2500 OZ with ZERO leaks!
I pumped during EVERY nursing session for 5 months straight, in an effort to bank as much milk as possible for my second baby. In that time, I froze and stashed 2500 ounces of breastmilk. With my firstborn I used a variety of different bags, but was having problems with leaking, so I eventually settled on these. So with my new baby, I already knew that these bags would be my go-to for what I was about to attempt. I have used the Nuk bags exclusively the entire time, and went through about 640 bags to get to 2500 ounces when I stopped, and we have had NOT ONE LEAK.I can’t really speak for the measurements on the bag because I didn’t really use them... since the weight of breastmilk itself can vary depending on a number of factors like how much water you drank or fat you consumed that day. I weighed my pumped milk with a small digital kitchen scale and used those weights for my ounce measurements.I never once spilled milk while pouring it into the bag for storage...I held the bag in one hand with the top lip/spout folded down and out of the way, and poured the milk in from the pump bottle with the other hand. Zipped it up and laid it flat for freezing to optimize storage space. Done, zero issues.The most I ever stored in one bag was about 6 ounces, but the majority of my frozen bags held 5 ounces exactly because I estimated that was how much my baby would be eating in one sitting by the time he was 6 months. It also made the most efficient use of the capacity of the bags without pushing their capacity limits, and I could fit 11 five ounce bags snugly into a gallon size freezer ziplock bag (I call them milk bricks), for optimized freezer storage space. By the time I was done I had saved about 48 milk bricks in my freezers.My son is now exclusively drinking my frozen breastmilk, so we have already thawed about 150 of the bags. We place the frozen bag in a bowl of warm water for a few minutes to allow it to thaw and warm, and then pour from the bag into his bottle. The flap/spout at the top of the bag allows us to pour without spilling one drop. Again. Zero leaks during the thawing process.Honestly, these bags were perfect... we definitely put them to the test and they held up beautifully. They were one of the most affordable options available that from my experience ensured the quality I was looking for, and when you’re saving your precious liquid gold that you worked SO HARD to make, you want the most reliable option you can find!100% recommend!

I exclusively pumped and used A LOT of bags. I used lasinoh, momcozy and Medela bags and these were my favourite. They felt sturdy and zipped tight. Didn't experience any leaks.
