Good containers for home-made baby food?

I've just recently started making my own home-made baby food. I'm 100% against anything in a jar, or formula cause of the things that are going on with stuff killing babys and stuff like that. So I decided to make my own baby food. My main question is does any one have any recommendations on some good containers to store my baby food in the freezer? I found a few containers online but I thought maybe there was a decent ziplock container. Something small and convient so when it's time to eat all I need to do is take it out and thaw it or warm it up. So I guess it needs to be BPA free.
