Leak-resistant, even when laid flat, these handy bags can store frozen breast milk for up to 6 months and can be pumped directly, saving time and preventing any messy milk transfers or spills. Our breast milk storage bags are made of food-safe polyethylene and are strong and flexible, so they won't leak, even when laid flat. Use Lansinoh breast milk storage bags easily: open the bag, fill it by pouring breast milk directly into the bag. Or use a Lansinoh breast pump to pump directly. Exhaust the air, seal, and record the date and amount!
