Hello Jessica, Thank you for sharing this feedback on our Breastmilk Storage Bags. We're sorry to hear about your experience with them. Lansinoh® bags use a premium monolayer film that is very strong but also more elastic (easier to stretch and work with) than other competitive brands which use a more rigid laminated film. Our Breastmilk Storage bags should not be placed in a microwave or bottle warmer. Please retain your product and reach out directly to wecare@lansinoh.com with your best contact information. A member of our Consumer Affairs team will get back to you to learn more about your bags. We look forward to working with you.

Hello Abbigale, We're so sorry to hear about your experience. We take these sorts of reports very seriously, and will do everything we can to provide the resources you need. For the best performance, we recommend filling with six ounces or less, removing the excess air before sealing, and laying flat to freeze. Having said that, we'd like to learn more. Please retain your product and reach out directly to wecare@lansinoh.com with your best contact information. A member of our Consumer Affairs team will get back to you to learn more. We look forward to hearing from you.
