Benefits of Breast Milk Storage Bags

Most new moms often wonder why they can’t use a ziplock grocery bag to store their extra breast milk. After all, you use them to store adult food, so why not breast milk? Here’s why the best breast milk storage bags are better:

  • They have designs that prevent any spills, contamination, or leaks of breast milk.
  • These bags are BPA-free and thicker than grocery store ziplock bags. Their heavy-duty nature enables you to thaw, freeze, and warm milk without removing it from the bag.
  • A breast milk storage bag is pre-sterilized. This allows you to store the breast milk directly without worrying about any contamination. It also minimizes the risk of the baby becoming sick from any food germs.
  • Unlike most food containers, pouring milk from a breast milk storage bag is easier.
  • They are more durable.

However, it’s essential to note that breast milk storage bags are not the same as bottle bags. Bottle bags are flimsier and are only useful for feeding your little one.

Types of Breast Milk Storage Bags

The two types of breast milk storage bags are:

Food-Grade Plastic Bags

These are storage bags that are BPA-free. This ensures that your child is safe from chemicals and keeps the bag from smelling like plastic. They usually come pre-sterilized and, because of this, are disposable and designed for one-time use only.

Storage Cups

These are special cups you can use to store breast milk. Unlike normal containers, these storage cups are designed for the purpose of storing breast milk. They are also dishwasher safe.

What to Look for When Choosing the Best Breast Milk Storage Bags

Purchasing the best breast milk storage bags can be a challenge without the right knowledge. The things you should consider are:


The quantity of milk expressed is different for every mother. Therefore, look for a size that can fit the amount of breast milk you express. Most storage bag brands come with quantity markings, which makes it easy to choose one that fits all your milk in one go.


The second most important factor is the durability of the bag. You don’t want to lose any of your precious milk through a leak, do you? Look for storage bags with durable and soft materials, as well as being chemical-free.


Look for breast milk storage bags that are easy to use. It should also stand upright and easily pour milk without making a mess. The containers should also have sturdy seals that can help prevent any leaks from occurring.

Food-Grade Plastic

Ensure you select storage bags that are made from food-grade plastic. This ensures that the bag doesn’t leave the breast milk with the taste of plastic.


The last feature you should consider is whether you can pump milk directly into the storage bag. With such versatility, it makes the entire process easier.

For storage bags that don’t come with a specific breast pump, you can try mixing and matching. Try to check and see if the storage bags come with adapters you can use with your pump.


Faqs About Breast Milk Storage Bags

Here are some common questions moms ask about breast milk storage bags.

Can I Reuse Breast Milk Storage Bags?

No, not all breast milk storage bags can be used twice. And here are a few reasons you shouldn’t reuse these bags:

  • Most storage bags lose their pre-sterilization effects after the first use. It becomes challenging to sterilize them again due to the material.
  • Breast milk storage bags are budget-friendly and designed for one-time use only.
  • Reusing storage bags can increase the risk of breast milk contamination.

However, you can reuse breast milk storage cups, as they are easy to sterilize even after the first use.

How Long Can Breast Milk Last in a Storage Bag?

Experts like the CDC have provided safety regulations on how long to store breast milk in a storage bag. However, these guidelines depend on the use and storage of the milk.

Freshly pumped milk stored at room temperature can only be stored for four hours. If it’s refrigerated, it can last for four days. If it’s kept in the freezer, then the milk can last up to six to 12 months. For thawed breast milk kept at room temperature, it can last for one to two hours.

If it’s refrigerated, it can last for 24 hours. Remember, never freeze breast milk after thawing. For leftovers, make sure your little one drinks it within two hours.

How Should I Thaw Stored Breast Milk?

To thaw frozen breast milk, start by removing it from the freezer. Next, proceed by running the bag or cup through warm water. Remember, never use a microwave to warm milk while inside the storage bag or cup.

How Can I Tell If Stored Breast Milk Is Not Fresh?

Your child’s health is important, and no mum can serve their little one spoiled milk. Therefore, it’s important to check the state of the milk every time. Ensure you smell breast milk that exceeds its stay in the fridge for over three days. This will help minimize your chances of giving your little one spoiled milk.

Tips You Can Use to Handle Breast Milk Storage Bags Efficiently

  • Don’t overfill the bag as this can jeopardize its sealing capabilities.
  • Always place the storage bags at the back of your freezer. Storing it at the front shelf of your freezer can cause the breast milk to be exposed to different temperature variations.
  • Never mix two batches of milk in one bag to save space.

How to Use Breast Milk Storage Bags
