If you can, there are some great borosilicate glass containers out there. I use them for everything. The ones I have seal well enough that I can fill it with soup and stick it in a backpack, ride somewhere and it's fine on the other side.
Thick enough to be basically unbreakable, microwavable, dishwasher-safe, etc. Don't need to worry about tomato staining either like on plastic. I've been thrilled with mine.
