It mostly depends on how long you want your meat frozen.
For short-term freezing, you should wrap the meat in freezer paper with the wax coating on the meat and the paper on the outside. This should be tightly sealed and taped, and then wrapped in aluminum foil for extra protection.
Freezer bags and butcher paper are the best options for long-term freezing. The butcher paper should be wrapped in the same way as freezer paper, with aluminum foil acting as a second barrier. These are the thickest materials that help to keep meat fresher for longer, as freezer paper isn’t strong enough to maintain oil, grease, blood, and liquid for long periods.
For the protection of your freezer, wrap meat in freezer bags or butcher paper and aluminum foil.
