You'd need a shrink-wrapper, or you could get some shrinkwrap paper at home depot and then use a hairdryer to seal it. Thing is that it won't be the right size so it won't look quite right without the shrinkwrapper.

If you have any buddies that work at gamestores, all of em have a shrinkwrapper, though. They play games and then reseal the packages as new all the live long day.
