Q1: Are Silkmum storage bags safe for my baby?
A: Absolutely. Our bags are made from high-quality, food-grade materials that are 100% BPA, BPS, and Phthalate-free. They are FDA-approved and come pre-sterilized, ensuring your milk stays pure and safe.

Q2: Do I need to wash or sterilize the bags before use?
A: No. Every bag is sterilized during production and sealed for hygiene. They are designed for immediate use straight out of the box to save you time and ensure maximum cleanliness.

Q3: How do the bags prevent leaks?
A: We use a Reinforced Double Zip Seal. This two-track closure provides an airtight, leak-proof barrier that prevents spills and protects your milk from absorbing odors in the refrigerator or freezer.

Q4: Can I store the bags lying flat?
A: Yes! While the bags have a self-standing base for easy filling, they are designed to lie flat in the freezer for optimal storage. This saves space and allows the milk to thaw much faster and more evenly when you're ready to use it.

Q5: What is the best way to thaw the milk?
A: Place the sealed bag in a bowl of warm water or leave it in the refrigerator overnight. Note: Never microwave or boil the bags to preserve the milk's nutrients.
