Well, the Ball jars work best if you can get them to seal as well, but typically, if you're "canning" stuff to be sealed, you need to heat up the contents, cover them, and then let them cool to get the air-tight seal.. There are these things called "C-Vaults" which are allegedly much better than the Ball jars because they are like the jars @witchyhour posted, but have a much better seal.. I've never used them but know a few folks who do and they say they work better..
