Of course... but the point is that once you open that seal it's not vacumm packed any longer and you have to repack it.

I got my sealer from WalMart. They're kinda expensive at $70-$100, but they pay for themselves in the amount of money they save you for stored foods NOT going bad...as well as the ability to keep frozen rodents good a lot longer.
Mine is a FoodSaver. Works great!
