Rubbermaid plastic bins.
Don't use aluminum at all. I just stay away from metals on a whole. I have no trust in plastic bags either. If your meat has an exposed bone, it's bound to puncture it. I also find with that so much liquid in the bags even the toughest zip locks leak at the seams after a bit of handling and what not.
