How did we get our start?
Adhering to the brand concept of “redefining comfort with scientific design”, Momcozy has been committed to providing the more comfortable and high-quality mom & baby products in the global market since its establishment in 2017. Most members of our team are mothers with children.

What makes our products unique?
Focusing on the three major areas of quality, function, and appearance, Momcozy continues to optimize product performance in terms of humanized design, material upgrades, and process innovation.
TEMP-Sensing Discoloration: Help parents to keep track of milk temp at any time. Purple is Cold (<36℃/96.8℉), blue is Optimum Feeding Temperature (36-40℃/96.8-104℉), and white is Hot (>40℃/104℉).
Double Strong Sealing: Designed with double sealed side seams & double zipper to protect and freeze breastmilk. When sealing, press your fingertips and make a sound. Presterilized & BPA free thickened milk bag, safely build your milk bank.
Zero Contamination: Milk import/export separation design ensures that there is no contamination. Simply open the sealing strip when pouring milk, and cut along a cutting line when you need to breastfeeding. It’s that easy!
Space-saving Design: Breast milk storage bags can be freezed super flat or upright. This unique feature also allows defrost or freeze milk quickly. Friendly Tips: Capacity is not exceed 6OZ. After milk is poured into the bag, it is necessary to release the air. After thawing, heat it to 40°C (104°F).

Practical and safe breast milk storage bags
These bags are excellent quality. They are strong, easy to seal, and completely leak-proof. I really like the temperature indicator—it makes it simple to check if the milk is safe for the baby. There’s also enough space to write the date and amount. Very practical and reliable for storing and freezing breast milk.

Best Milk Storage Bags I Have Ever Used
These Momcozy Milk Storage Bags are excellent—the best I’ve used so far. They feature a secure double zipper seal that has proven to be completely leak-proof, even when freezing and thawing. The bags are thick and durable, and the area for writing the date and volume is easy to use. They also freeze flat, which saves a ton of space. Highly reliable and essential for any pumping mom!

Love love LOVE!
These are such good pump bags. They tear super easy in the corner when you need, they don’t leak, the temperature gauge is so helpful for sink warming milk, and they fit so much milk. We love them!

Temp sensing, easy thawing, great quality
Absolutely love these and will be purchasing again. The temp sensing on the bag was so great for thawing, ran them under hot water when i needed a quick bottle on the go. Very quick and easy to travel with and no leaking at all. It also comes with so many this pack lasted me a really long time

No downfalls yet
I’ve been using these for about a week & a half. I started with the Lansinoh bags but they fell apart in my momcozy bottle warmer when I thawed them from frozen. Milk was everywhere. With these, I can thaw them in the warmer & they keep their structure. They’re pretty sturdy bags, actually. Everything I have is momcozy— the bags, the pump & the warmer so I imagine they were intended to be used together. They do not buckle when I pour my milk in from the pump (& I usually pour them FULL like 6-7 oz). The bottom opens up & flares out when they’re full making them self standing so that’s nice. My husband lays them horizontally in our freezer & the bottom collapses again to freeze them flat so we don’t have any issues with space. I have held them upside down, played w the milk inside like a squishy, & simply dropped them & haven’t had any issues with leaking. They’re built tough. I will consistently buy them for storing milk. It’s a really nice, thick plastic bag. I wouldn’t reuse them or anything, definitely once & toss, but they’re worth the money spent for sure.

Great quality bags.
These are great bags! Great quality and has good storage capacity. Love that they have the temp sensing on them as a second back up for making sure the milk isn’t too hot or too cold. Very functional!

Great quality
These are great! The blue and purple colors are really just two different colors or purple. So that was a little confusing at first. Haven’t had any to leak. They are easy to use. They are a quality thick plastic like Motif or sprucely bags. Not like the thin Lansinoh bags.
