180 CT (3 Pack of 60 Bags) Value Pack Storage Bags - 7 OZ, Each PRE-STERILIZED by Gamma Ray, BPA Free, Leak Proof Storing Double Zipper Seal, Self Standing, for Refrigeration and Freezing

Ok so I bought these thinking, “hey they hold up to 7 ounces max, are about the size of name brand Lansinoh (though, Lani can hold up to 8 oz, I never put more than 7 oz into the milk bag at a time) the opening looks just as wide to fit over my breast pump attachment to pump directly in the bag too.” I was excited... alas, no. You should not ever fill up bags to recommended full line bc really it is overfull (most companies just fudge their measurements & it will cause bags to break or bust easier. I always only fill under 1 oz of their max - so if their max is 7oz I don’t go over 6oz). When I opened the packaging I was disappointed to see: no double zipper/secure closing (updated to say: they do actually have a double zipper! It’s just so crappy it doesn’t look like but 1, like on a ziplock bag, the quality is obviously not a priority, still with their double zipper it’s not a secure closing), & the thickness was overly bulky like most cheap brands (thickness does not mean better quality!), & within minutes I’ve found what looked like a wide enough opening for the breastmilk bag was not meant to be for my breast pump so I could pump directly into bag (it didn’t fit). The opening of the bag is actually very small bc the thickness of the bag prevents it from being able to open up.It states it also holds 7 oz. I would not recommend anyone put 7 oz into these breastmilk bags, ever. As you can see from pictures, the bag will not lay down flat (as compared to Lansinoh, both holding 6 oz only, not even 7. These bags really aren’t even made for more than 4 oz, maybe 5 oz max). After finding out that it wouldn’t fit my breast pump parts, I went on to test the bag & how flat it lays. I measured 6 oz from a bottle & weighed it as well to be exact (with water). The Lansihol bag was weighed as well with breastmilk bc it was already done from yesterday’s pump. Both 6 oz exactly, both look very different. Laying breastmilk bags down flat isn’t just about storage (it is a big part), but will also help prevent from breaking or busting the bag, & leaks.I also flipped the milk bag upside down to check to see if it leaks, I only gave it a small squeeze, and wouldn’t you know.... it leaks!!! So, technically, I shouldn’t use any of these bags, nor should you, if they’re leaking from a little pressure holding less than their recommended max (& yes, it was fully closed, I double checked). You want the breastmilk IN the bag, not OUT of the bag! I really wish I didn’t waste my money & I bought the 180 count, now I’m out of $20 for a bad product.

I have used medela, Lansing, up&up, and these. These bags are the best! They are sturdy. They don't get leaks. They have a small lip for easy pouring. Seriously this is the only brand I like.

Update** after trying multiple other bags and having them break on me, I do have to say now that I have gotten to these from my freezer stash, these bags are very thick. I haven't had not one leak on me. That's most important so I give these a few more stars. Still not my favorite as I over produce and need as much space as possible and these don't give much room in my freezer. But, these definitely are strong think bags.I really wanted to like these bags. For the price and how many you get it would be a steel however, these bags are REALLY hard to open! The zip on them makes it almost impossible! I've used 3 different freezer milk bags and these seem a bit excessive on the "zip lock" also another plus WOULD BE that these hold 7 oz. While most others only hold 6. But again after freezing them laying flat, the bottoms bow out a lot more making them less convenient for storage. My end thought is, I will not be recommending these nor buying them again. Pictures are to show how I would expect laying the milk flat should look like with another brand and how it does look like with this one..

I was nervous because there are so many reviews about them leaking but I've had zero issues with that. They've held up great, exactly what a milk storage bag should do. They were exactly what I needed... A lot for costing very little.

The bags are nice and sturdy. The opening to the bags are a little smaller so you can't fit the bigger top bottles into the opening to dump it, but smaller bottles like ameda and medla work well. One thing I am not sure if it is common or not is out of one of my 60 count bags I had 5 bags leak out of the side under the ziplock. I don't know if when they were made they weren't all the way sealed or what. I tried to contact the company about it, but never heard back from them.

These bags are almost identical to the Medela bags except that they can hold 7 oz instead of 6 oz.; the plastic feels the same as Medela, its firm. So far no leakage and they can stand up. Won't hold any more than 7 unlike the Lansinoh bags that have a tiny bit more room. I like that they come in a box of 180 though.

The zipper feels super secure. The top is perforated, so it is easy to use when you don't have access to scissors. They are sturdy in the freezer and we're the best value I could find at the time I bought them.

THIS ONE IS THE BEST! It's thick so the milk doesn't seep out, it warms the milk quickly, it freezes flat to save freezer space and it's perfect with a permanent marker (without any second thoughts that the ink could seep through). It's higher quality than most other bags. The Kiindes are great but they don't freeze flat. The Lanisoh ones are really cheap but they rip easily and milk can often leak after frozen.
