/Gerber Seal N Go Breast milk bags, 6 Ounce, 50 Count

Good

These are my first breastmilk bags so i don't have others to compare them to. They do the job. One thing that bothers me about them is that they are a bit difficult to open and keep open when you are pouring the milk in.

Fast shipping from seller. Bags have a strong plasticky smell. And have a tendency to leak if liquid is above 4 oz. In general I think the Lasinoh bags are better.

We have twins and are having frozen breast milk shipped to us via fedex twice a week on a combination of wet ice and freezer packs in a styrofoam container (Insulated Shipping Containers, 13 3/4" x 11 3/4" x 11 7/8"; http://www.amazon.com/gp/product/B000ZJSH3I/ref=cm_cr_ryp_prd_ttl_sol_6). The bags were not overfilled and were frozen flat. We found out early that some bags do not hold up well so I ordered every single breast milk bag I could and kept track of how they did (I am a scientist). Here are the results from worst to best (NOTE: this review is most relevant if you are shipping breast milk as fedex is not gentle on packages; if you are not shipping other bags we don't like might be fine but I can tell you which is best overall). Hope you can learn from our experience.Honeysuckle breast milk storage bags: terrible. More than half of these broke during shipping whereas in the same shipment other bag types held up well. I would avoid these.Lansinoh breast milk storage bags: second worst. About 1/4-1/3 of these typically broke/leaked upon shipping. It is not hard to tell they are the flimsiest. P.S. If you use these, a tip I found to help thaw them is to put each bag in a zip lock so it the bag leaks you can still use what stays in the bag (versus what leaks into the ziplock).Medela breast milk storage bags: ok, not great. Hold up better than Honeysuckle and Lansinoh. About 1/6 - 1/5 of these would break/leak. They are also more difficult to pour out of and tend to lose a little milk in the pouring process (trick is to pour fast out of these).Ameda breast milk storage bags: never used them as they come with twist ties and not ziplock seals.Dr. Brown's breast milk storage bags: work great. never had one break. stand up well on their own. very easy to pour out of. Recommended except there is an option just as good and cheaper.NUK/Gerber Seal N Go Disposible Liner: the winner! One bag out of very many has leaked. Stayed intact even when other bags did not survive. Good to pour out of (not as easy as Dr. Brown's but good enough). Thaw well. Better priced than Dr. Brown's (which is why we went with these).

For my first baby, I used the Medela milk storage bags. We encountered many problems with those. They'd leak while thawing, were thick even when compressed to a flat brick and took up more storage space in the freezer, and only had a single ziplock seal. Additionally, you had to tear off the sterilized part and the silly straps with each bag. Since I didn't use the attachment part for the breast pump (I found this to be a MESSY way to pump, and chose instead to pour from a bottle into the bag), there really was no reason to stick with the Medela brand.I've used this brand for my second baby and, let me tell you, they are a night and day difference to the Medela ones! Not only are they cheaper. They fit more milk (if you want to store more), or if you stick to 4-6 ounces they freeze much flatter and take up less room in the freezer. They freeze flat on their own. I found with the Medela ones, because of the stand-up design, I had to squish them between two flat objects (I had the compression storage box) to achieve a desirable "flat" shape - which was often askew and didn't store well anyway. The plastic on the NUK/Gerber brand seems very durable and I love that there are 2 seals, just in case! We went through 2 boxes of these and not a single leak (except for the one my husband dropped on the floor). Additionally, I didn't encounter any strange milk smells from using these bags. I highly recommend!

A COMPARACIÓN DE LAS BOLSAS MEDELA QUE YA ME HABIA DADO LA OPORTUNIDAD DE PROBAR, ESTAS LAS SIENTO MAS LIGERAS, PARECEN UNA BOLSA COMUN Y CORRIENTE, CUMPLEN SU FUNCION DE ALMACENAMIENTO QUE ES BASICO... QUE DE FORMA GENERAL ESTAN BIEN NO EXCELENTES.
