Breast Milk Storage Bags

Introducing Wonderbewbz Breast Milk Storage Bags

Designed by mums, for mums.

Our breast milk storage bags are the culmination of handling over 23,000 bags (as of February 2025) in our daily operations. We've taken the best features and improved upon the rest to bring you a storage solution that truly works.

Key Features:

• Thicker, Triple-Layered Material: Prevents freezer burn and ensures durability, so your precious milk stays safe and fresh.
• Double Zip Seals: Provides extra security against leaks, giving you peace of mind whether storing in the fridge or freezer.
• Inner Spouts with Rectangular Design: Eliminates awkward shapes, making pouring neat and effortless.
• BPA-Free & Food-Grade: Your baby's health is our priority; our bags are made from safe, pre-sterilized materials.
• Optimal 180ml Max Fill Line: Designed to prevent overfilling and overstretching, while 150ml or below is best for flat freezing to save space.
• Transparent with Gusseted Bottom: Easy monitoring with a self-standing design for convenient storage options.
• Writable Space Above Zipper: Label dates and notes without risk of ink contaminating your milk.
• Minimalistic Design: Sleek and functional, reflecting the elegance of simplicity.

Why Choose Wonderbewbz?

After encountering countless brands, we've seen it all - the good, the bad, and the leaky. Our hands-on experience has driven us to create a bag that addresses common issues like tearing, leaking, and storage inefficiencies. With Wonderbewbz, you're choosing a product born from real-world use and a deep understanding of what mums truly need.

Optimal Storage, Designed for Real-Life Use

Our 180ml max fill line is designed to prevent overfilling and overstretching, ensuring durability and leak resistance. For optimal flat freezing, we recommend filling up to 150ml or below. This keeps your milk storage organized, compact, and safe without bulging in the freezer.
