Operating Instructions
Filling the Bags:
- Ensure the bag is clean and dry.
- Open the wide mouth of the silicone bag.
- Carefully pour breastmilk or baby food into the bag. Each bag has a capacity of 12oz (360ml) and features visual measurements for accurate portioning. Do not overfill.

The 4.3-inch wide mouth design facilitates easy pouring and cleaning.

Each bag holds 12oz (360ml) of breastmilk, with clear volume indicators.
Sealing the Bags:
- Once filled, gently squeeze out any excess air from the bag.
- Slide the plastic sealing rod firmly across the top of the bag to create a double leak-proof seal. Ensure the seal is completely closed to prevent leakage.

The double seal design ensures no leakage, keeping your breastmilk secure.
Storage:
Nuliie bags are designed for versatile storage in the refrigerator or freezer. They can be stored upright or laid flat to save space.
- Refrigerator: Store filled bags upright or flat in the refrigerator.
- Freezer: For freezing, lay the bags flat initially to freeze evenly, then store upright or stacked to maximize freezer space.
- Labeling: Use the provided label stickers to record the date and volume of breastmilk for proper rotation.

Bags can be stored upright or flat in the refrigerator or freezer to optimize space.

Reusable and BPA-free, these bags come with labels for tracking date and volume.
Thawing and Heating:
These breastmilk bags can withstand both cold and heat. Frozen milk can be thawed and warmed using various methods:
- Bottle Warmer: Place the bag in a bottle warmer.
- Warm Water Bath: Place the bag in a bowl of warm water.
- Microwave: Use with caution. Ensure milk is evenly heated and check temperature before feeding.
- Oven: Use with caution for warming, ensuring temperatures are appropriate for food-grade silicone.
Always check the temperature of the milk before feeding it to your baby.

The bags are compatible with bottle warmers for convenient heating.

Troubleshooting
If you encounter any issues with your Nuliie Silicone Breastmilk Storage Bags, please refer to the following common solutions:
- Leakage: Ensure the plastic sealing rod is fully and firmly slid across the top of the bag, creating a complete double seal. Check for any damage to the silicone or the sealing rod.
- Difficulty Sealing: Make sure the edges of the silicone bag are clean and dry before applying the sealing rod.
- Odor Retention: While rare with food-grade silicone, strong-smelling foods or improper cleaning can sometimes lead to odor. Ensure thorough cleaning and disinfection. Soaking in a baking soda solution for a few hours can help neutralize odors.
- Stains: Certain foods may cause temporary staining. This typically does not affect the safety or functionality of the bag. Ensure prompt cleaning after use.
