Breast Milk Storage Bags Lansinoh 20417 — pack of 4, disposable pre-sterilized bags for freezing and storing expressed milk

Lansinoh 20417 breast milk storage bags are a pack of four disposable, pre-sterilized bags designed for hygienic freezing and short-term storage of expressed breast milk. Each bag is made from a multilayer film that provides a secure barrier against leaks and freezer burn while maintaining milk quality during storage. The clear writable area on the front allows parents to record date and volume, and the wide opening and secure seal make pouring and sealing straightforward. The bags are compatible with many standard breast pumps and fit common storage systems, enabling organized, space-saving milk handling in refrigerators and freezers.

Advantages

These Lansinoh storage bags come pre-sterilized to reduce the risk of contamination and save time on preparation. The double-seal closure ensures a leak-resistant barrier, and the sturdy film minimizes the chance of punctures or cracks in cold storage. The transparent design and writable labeling area allow accurate tracking of collection dates and volumes for safe rotation and feeding. Designed for direct pouring from pump flanges or transfer via a funnel, the bags simplify portioning and freezer organization.

Suitable for

• Freezing expressed breast milk for later use
• Short-term refrigerated storage and organization
• Portioning milk by volume for single feeds
• Transporting milk between home, work, and childcare settings

Key specifications

• Pack quantity: 4 disposable bags
• Material: multilayer sterilized film for leak and puncture resistance
• Closure: double-seal, leak-resistant seal
• Writable label area for date and volume

How to use

Before use, check each bag for integrity and the sterilization seal. If pouring directly from a breast pump, follow the pump manufacturer’s guidance and pour breast milk into the bag’s wide opening or attach a compatible pump adaptor if available. Record the date and volume in the writable area before sealing. Close the double-seal firmly to prevent leaks, then lay the bag flat in the freezer or stand in the refrigerator as recommended for the intended storage duration. Thaw frozen milk in the refrigerator or under warm running water and gently swirl to mix; do not microwave.

Usage recommendations

Store bags flat to maximize freezer space and promote even thawing. Use older milk first by labeling each bag with the collection date. Do not refreeze thawed milk. Follow safe handling practices: wash hands before expression, handle bags by sealed edges, and inspect contents after thawing for any off-odors or color changes.
