7 of the Best Plastic Bottles for Breast Milk Storage

Plastic breast milk storage bottles are durable, reusable, and designed to withstand the freezing and thawing of breast milk. They're stronger than breast milk storage bags, less expensive than glass containers, and hold more breast milk than storage trays. Plastic bottles are also convenient. You can often use the same bottle to collect your breast milk directly from your breast pump, store your breast milk, and feed your baby.

Using Plastic Bottles With a Breast Pump

Some plastic breast milk collection containers can only be used with a particular breast pump. Other containers are a standard size and work with pumps that use standard size collection containers. Some pumps have adapters that let you use other brands or types of collection containers.

So, before you purchase breast milk storage bottles, check to see which ones are compatible with your pump. 

What to Look for When Buying and Using Plastic Bottles

Look for food-safe, BPA (Bisphenol A)-free plastic storage containers. Some bottles are sold in pre-sterilized packages, while others have to be washed before you use them.

Before you use your storage bottles for the first time, read and follow the package instructions carefully.

Pros of Plastic Breast Milk Storage Bottles

  • Plastic breast milk storage bottles are time-savers since you can use the same bottle for pumping, storing, and feeding.
  • Plastic storage bottles cost less than glass bottles.
  • Frozen breast milk stored in plastic bottles thaws out more quickly when compared to breast milk in glass bottles.
  • Plastic bottles do not break as easily as glass bottles, and they're stronger than plastic storage bags.

Cons of Plastic Breast Milk Storage Bottles

  • Plastic bottles are not disposable like breast milk storage bags. You need to wash them after each use. 
  • Bottles take up more storage space in the refrigerator and freezer compared to plastic storage bags.
  • You have to make sure that your storage bottle has an airtight seal, so you have to use bottles specifically designed for use in the freezer.
  • You cannot fill a breast milk storage bottle to the top if you plan to freeze it. You should only fill it 2/3 to 3/4 of the way to allow for the expansion of your breast milk during the freezing process. If you overfill a bottle, it could burst.
