Freezing chicken

Okay so I cooked a lot of chicken plain in the crock pot and shredded it. I was planning to split it into portions and freeze it to use is casseroles. Buuuuut I don't have any freezer bags. Or regular zip lock bags. I have no idea how that happened. I'm going in the hospital Monday and I have absolutely no time to go to the store and get any.

So how can I freeze this crap? Can I wrap it in foil or cling wrap or something? I have a lot of Rubbermaid storage bowl things. Are those good for freezing? I have no idea lol.

usually i wrap in clingy wrap, and then foil over that

if cling wrap is what i think it is then yes that will work .

I would probably wrap it in plastic wrap and then foil and put it in.

Or, maybe I'd wrap it in plastic wrap tightly and put it into the tupperware.

Okay cling wrap and foil it is, thanks!
