I posted this link on the other thread but I think its informative enough to warrant posting a second time: Freezer Burn

Although I know that frrezer burn is basically a result of the meat dehydrating during storage, I still find it amazing that this can happen when the water is in a deep frozen state.

Earlier in the thread, frost free freezers were mentioned. To be frost free they must dehumidify the air in the freezer compartment. Couple that with the fact that neither butchers paper nor the various plastic wraps/bags are made from a truely airtight material, and you can see how meat packages can start to dehyrate during storage, with the plastic bags used in vac-packers being the exception...
