Excellent advice from traindiesel above, especially if you're planning to unpack shortly after the move. Additional things to consider if the storage will be longer term are protection from the elements, stackability, and ability to identify the contents.
I like the weathertight plastic totes for trains that I take to shows - they're pretty rigid, seal tightly, and are semi-transparent. However, they can get pricey, but shopping around can reduce the cost. Many of the cheaper plastic totes will buckle when stacked and don't offer great protection.
