Hi,
Put them in a zip loc bag. Those plastic containers aren’t meant to be frozen but are good as storage so you can wash and reuse if you want.
Recommend just patting them down with paper towel before you do or spreading them out on a towel to air dry briefly. If they are wet they will stick together when frozen...same goes for any veggie.

I freeze peppers and blueberries and strawberries. I found it good to dry and put on a baking pan and freeze for about an hour or two uncovered or until they are frozen. Then you can just dump the whole thing in a zip loc and they are individually frozen.
