Stricktly from a physics point of view, I would imagine the only thing you would have to worry about is the air expanding or contracting. I don't think you would want those 65 year old vittles to explode or even seep out! My suggestion would be to keep them in room temperature - not hot or cold. But what do I know? I've grown up eating MRE's, right Rocky?!
