Breastmilk storage bag question

[AbiAbi]

Are they any different to regular freezer storage bags for food?

I want to express tonight but couldn't find any breastmilk storage bags in Sainsburys tonight.

TIA

i think they are sterile (but i might be wrong)

I think they are sterile too. Some bottles are freezable though if you haven't any bags.

Aha, that makes sense I guess.

Thank you both!

Yup, pre-sterilised. Some also have sticky straps so you can pump straight into them.
