Nuliie Silicone Breastmilk Storage Bags, 7-Pack 8oz Reusable Double-Seal Leak-Proof

Nuliie 7 Pcs Silicone Breastmilk Storage Bags are reusable, food-grade silicone pouches that hold up to 8oz (240ml) each and feature double seals for leak-resistant freezing, heating, and feeding.

These silicone milk storage bags are designed as a reusable, eco-conscious alternative to single-use plastic breastmilk bags. Made from thick, food-grade silicone that is BPA-free and non-toxic, each pouch stands on its own for easy filling and has a wide-mouth opening for straightforward cleaning and transferring. The set includes seven 8oz bags, measurement markings, and label stickers so you can organize and track milk volume and dates.

How do these bags prevent leaks and spills?

The Nuliie silicone pouches use two separate seals—an inner and an outer closure—built into a single molded piece. This double-seal design dramatically reduces the risk of accidental leaks during storage, transport, or freezing.

• Inner and outer silicone seals for redundant protection
• Thick, one-piece construction eliminates seam failures
• Easy-grip closure to prevent slipping while sealing
• Stand-up form reduces tipping when filling or storing

What makes them easy to clean and use every day?

Each pouch has a wide opening so you can access the interior for thorough hand washing and dishwasher cleaning. The large mouth also simplifies pouring pumped milk, adding solids or purees, and fitting into bottle warmers or cups when reheating.

• Wide-mouth design for fast, complete cleaning
• Dishwasher-safe and hand-washable materials
• Transparent silicone with volume scale for quick measurement
• Label stickers included to note date and amount

Can I freeze, heat, and transport milk safely in these pouches?

Yes—the silicone construction tolerates a wide temperature range so you can freeze pouches flat or upright and reheat them in compatible warming devices. Their compact, flexible shape also makes them convenient for carrying in cooler bags or diaper totes without taking much space.

• Freezer-safe for long-term breastmilk storage
• Compatible with bottle warmers and safe for microwave reheating when used correctly
• Flexible, space-saving shape for travel and storage
• Works well with portable breast pumps for direct transfer

How much milk does each pouch hold and how are they organized?

Each silicone pouch stores up to 8oz (240ml) and includes visible volume markings so you can portion accurately. The set of seven gives you a week’s worth of storage options, and included label stickers help you track pumping dates and volumes.

• 8oz / 240ml capacity per pouch with measurement scale
• Seven reusable pouches included in the set
• Transparent material for quick content checks
• Label stickers for date and volume tracking
