Breast Milk Storage Bags

Information, the Pros and Cons, and Six Popular Brands

Your breast milk is an incredible fluid full of the nutrition your baby needs to grow and immune-boosting properties to protect your child from illness and disease. When you decide to pump and store your milk for your child, you want to choose a storage container that will protect it. Breast milk storage bags are one option. Keep reading for information about breast milk storage bags, the pros and cons of using them, and six brands to consider. 

Breast Milk Storage Bags

Breast milk storage bags are plastic bags made specifically for the collection and storage of breast milk. They are designed to withstand the freezing, storing, and thawing process. Since they are pre-sterilized, they're convenient and ready to use right out of the box. When choosing a brand of storage bags, you should look for reliable seals, and quality construction to prevent leaks.

With some brands of breast milk storage bags, you have to pump your breast milk into a separate container and then transfer it into the bag to store. Other brands come with a convenient adapter that allows you to pump directly into the bag. Of course, with either option, when you're ready to thaw out and use the breast milk stored in the bag, you'll still need to transfer the milk from the bag to a bottle for your baby. 

Can You Use Plastic Sandwich Bags or Bottle Liners?

Ordinary plastic sandwich bags may look similar to breast milk storage bags, but they are not the same. Sandwich bags are not made to store breast milk. They are not as strong as breastmilk bags, and they are more likely to break during the freezing and thawing process. 

Bottle liners are great for delivering breast milk to your baby, but they aren't so great when it comes to storing your breast milk. Bottle liners are not made to withstand the freezing, saving, and thawing of milk. They aren't as strong as breast milk bags, so they are also more likely to tear and leak wasting your precious breast milk. 

It may seem more expensive to buy plastic bags designed specifically for breast milk storage, but it's worth it. Breast milk storage bags are stronger, more reliable, more convenient, and safer than bags that aren't meant for the storage of breast milk. 

Other Breast Milk Storage Options

Plastic breast milk storage bottlesfood-safe glass containers, and breast milk storage trays are other available storage options. There are advantages and disadvantages to each type of container. Here are the pros and cons of storage bags.

The Pros of Breast Milk Storage Bags

  • Breast milk storage bags are usually less expensive than plastic containers or glass bottles.
  • Bags are convenient and easy.
  • Storage bags are disposable, so you can spend less time cleaning. 
  • Breast milk bags aren't as bulky as glass or plastic containers, so they take up less storage space in your refrigerator or freezer.
  • Breast milk storage in bags thaws out more quickly than milk stored in glass or plastic containers.

The Cons of Breast Milk Storage Bags

  • Breast milk storage bags are meant to be used one time. They cannot be washed and reused, so they aren't as eco-friendly as the other storage options. Plus, over time, the cost of buying new ones can add up.
  • Plastic storage bags are not as strong as glass or hard plastic containers, so they're more likely to leak or break during storage. Not only is it messy, but any tear or opening can contaminate your breast milk.
  • You cannot pump directly into all brands of storage bags. You may have to express your breast milk into a container that's compatible with your breast pump and then transfer the milk from that bottle into the plastic bag for storage. The extra steps can be time-consuming.
