Item in Stock   |  

Store & freeze every drop of your precious breast milk with this box of 25 zip-lock storage bags that are leak-proof, pre-sterilised & self standing.  

Nuby breast milk storage bags are perfect for storing & freezing. They're self standing to help prevent spillages & pre-sterilised for that extra peace of mind. You can also write on the label your name (if you're planning on taking to your babies nursery or somewhere else) plus the date & volume to keep you on track & organised (useful if you have some of the infamous 'baby brain' creeping in). If size matters to you (chuckle all you like here), these bags have been made to hold approx. 300ml/10oz which is usually plenty big enough.

Made with a premium material that has a better oxygen barrier to keep breast milk fresher for longer while protecting & preserving nutrients (impressive hey?), they're honestly very handy to have if you're a breastfeeding mummy! 

Boxed Contents: 25 x Breast milk Storage Bags

Is this BPA free?

Yes this product is BPA free.

Are the Breastfeeding Milk Storage Bags Reusable?

No - they are pre-sterilised so unfortunately they are one use only. 

Do the Breastfeeding Milk Storage Bags need to be sterilised?

No - since they are pre-sterilised and one use only, you will never need to sterilise them.

How long can breast milk be stored in the Breastfeeding Milk Storage Bags?

According to the NHS guidelines you can store breast milk in our Breasting Milk Storage Bags:


  • In the fridge for up to 8 days at 4C or lower. (If your fridge is any higher than 4C use within 3 days.)


  • In the freezer for up to 6 months, if it is lower than -18C or lower.


Please note that breast milk that has been cooled in the fridge can be carried for 24 hours in a cool bag with ice packs.

How do I defrost the breast milk in the Breastfeeding Milk Storage Bag?

We would advise that you allow the breast milk to defrost overnight in the fridge. Alternatively, you can hold the bottle or bag under warm water (max. 37°C). Do not thaw or heat frozen breast milk in a microwave or in boiling water. This is to avoid vitamin and mineral loss and to avoid scalding your baby.
