Now you wouldn't think that water would be able to evaporate straight out of frozen food, but it can. You see, freezer air is so dry that it can literally rip water molecules off of frozen food, in a process called sublimation. The result? Frost on the sides of your freezer, and freezer burn on your food. This is especially a bad thing for meat, which can become so leathery and dry, that basically it becomes unpalatable. There is, however, one way to prevent this: proper packaging. Freezer-bound meats such as chopped steaks, fillets and cutlets, should be wrapped in at least two full layers of plastic wrap, and then that should be sealed inside at least two full layers of heavy-duty aluminum foil. And you might want to crimp in the ends just to ensure that no air can get in there. And, of course, you want to label that with a magic marker, the name of the product, and, of course, the freezing date.
