They sell an adaptor for the Medela to pump into their bags. Medela bags are smaller and I always pump at least 4 oz from one of my breasts. So I just cut a slit in the flap of these bags (There is a double purple line that I use) and use the Medela adaptor part. Works great! best tip I got as a BF/working/pumping mom. I hated coming home after 14 hours and having to transfer milk and wash and sterilize bottles. **Q: Can I reuse these bags or must throw away after use?** A: These bags are single use and are supposed to be thrown away. There's no way to "re-sanitize" them, so to speak. **Q: Can I pump directly into these bags from a Ameda pump?** A: I do it that way. i use tape to attach the tops of the bags onto the pump. i pump both sides at the same time.The 4 reasons i pump directly into the bag is 1-less waste, i dont waste/spill a single drop transferring from bottle to bag2-less work bc no bottle to wash out3-saves time bc i dont have to pour from bottle to bag or wash out the bottle4-less bacterial contamination because there's no transferring step **Q: Can this be use for Spectra?** A: Hi JT. Thank you for your question. Unfortunately, our Lansinoh pump adapters are not compatible with Spectra pumps. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great quality bags! *by I***A on April 30, 2026* These bags are very durable and easy to use. I’ve never had any leaks, and they freeze flat, which saves a lot of space. Highly recommend for breastfeeding moms! ### ⭐⭐⭐⭐⭐ Great product *by J***Z on April 19, 2026* These work really well. No spillage, thick plastic. Easy to use. Easy to freeze. Highly recommend ### ⭐⭐⭐⭐⭐ Better than Medela *by L***N on June 3, 2010* After discovering that Madela bags can make your milk smell and taste rancid, I switched. But, I also did a little comparison work: Lansinoh bags can hold up to 6 ounces of breast milk. Medela bags can hold up to 5 ounces of breast milk. Lansinoh: On the simplest level, the Lansinoh bag is easier to open and pour milk into than the Medela bag. The reason I find it easier is because of the material the bag is made out of and the bag is more pliable. You open the bag by removing a small strip that is perforated on the top. There are two seals on these bags, which is a huge plus. It's a comfort in preventing leaks. The reason why Lansinoh wins the freezing process is because they lay flat very well. I've found that when laid flat, the bag freezes into a solid rectangle of milk that is consistent in thickness. It is also easy to "stack" once frozen which is very helpful for organizing. It's also important to squeeze all the air out of the bag which is much easier to do since there is not a large plastic section at the top, like in the Medela bags. Medela: The Medela bags have the ability to be attached directly to a pump. As a result, there is a large plastic area on the top of the bag that is perforated. This makes these bags a little bit more awkward to open. Lansinoh: Since these bags are fantastic for the freezing process, they are easier to thaw because they are consistently the same thickness. They look like a perfect rectangle of frozen milk. Or you can freeze the bag standing up. My husband loves how easy it is to thaw these out. Way easier than Medela. Medela: Bag leaks when you thaw it and sometimes they leak in the freezer (which really is a mess). This is because there is only one seal instead of the double seal on the Lansinoh bags. ## Frequently Bought Together - Lansinoh Breastmilk Storage Bags, 100 Count, Baby Essentials, Fast Freeze & Thaw Breast Milk Bags for Baby Bottle Feeding, Superior Strength & Stretch, 6 Ounce - Lansinoh Stay Dry Disposable Nursing Pads, Soft and Super Absorbent Breast Pads, Breastfeeding Essentials for Moms, 100 Count - Earth Mama Organic Nipple Butter™ | Nipple Cream Safe for Breastfeeding | Postpartum Essentials for Nursing | Non Lanolin Nipple Cream, 2-Fluid Ounce --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/718261-lansinoh-breastmilk-storage-bags-100-count-baby-essentials-fast-freeze](https://www.desertcart.co.uk/products/718261-lansinoh-breastmilk-storage-bags-100-count-baby-essentials-fast-freeze) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-19*
