One of the best things you can do to help preserve food is to keep air *out* ... so the containers that are the most airtight are also the best at preserving. Freezing or keeping food cold is also advisable, because a container by itself can only do so much.
Seran or plastic wrap work pretty well. Tin foil also is a nice alternative if the others are not on hand. Overall, food cannot be preserved indefinitely by wrapping alone, but rather through freezing in order to preserve it as long as possible.
There are many types of containers and wraps that are suppose to keep food fresh. The best one will be airtight for sure, like Ziploc.
