I know my mother would come home from the store and re-wrap meat in freezer paper and put it in the freezer.
Maybe I'm lazy, but I just put the meat in its original package into a freezer ziploc bag. When I use the meat, I save the freezer bag in the freezer for the next package of meat, unless it doesn't look clean. I never use the meat bag for any other food. The bag is marked for meat only.
If I buy meat from the service meat counter at my store and I tell them it's for the freezer they will wrap it in freezer paper for me.
I leave bread in its original packaging in the freezer.
If it is buns from the deli, I put the bag into a ziploc freezer bag first because I have had the deli bag become brittle in the freezer and crumble.
