Bottle liners work for breast milk storage?

I used baby bottle liners and rubber bands years ago to store pumped bm and it froze just fine and defrosted easier according to the daycare. I also found that it saved storage space. Keep in mind that this was years ago. I have no experience with dry ice. Are you donating?

The first package of bottle liners I bought said that they were fine for storing/freezing milk. I think they were for the Playtex bottles. That was with DD1, though, who never actually successfully USED the bottle, and ended up snatching the roll of liners and decorating the kitchen with them. So I can't actually tell you how well they work. We never got that far with them.

The problem with using any bags is waste!!!!!Because these bags are a continued cost, we put what ever amount of ebm in them and when we need to thaw and make a bottle, we have to thaw 2 or more bags to get one bottle!!! : That is why I invented a better way.....Milk Trays allows moms to freeze ebm in single ounce servings that also fit into any bottle on the market!!!! That way when babies bottle is made, it is made to order....If she needs 3 oz grab 3 Milk Sticks melt and serve!!!
It has worked great for me, I am hoping to convert more moms to freezing their ebm this way it is best for them and for their babies.

Well, I would be freezing milk in LARGE quantities, so bags it would be for me. I looked into different trays, but ultimately it's more time and I still end up using bags (to ship milk or at least deliver locally).

Thank you all! I'll have to check out some different liners and see which I like.
