We use a ziplock first, squoosh the air out, and then wrap in heavy duty aluminum foil. The foil is secured with duct tape, and we then write the date and contents on the tape with a magic marker.
Vacuum packed chicken and meats on plastic trays get wrapped with heavy-duty foil.
Items that are vacuum packed in heavy plastic (sides of ribs, corned beef briskets, etc) go straight into the freezer.
I freeze homemade soups, broths and such in freezer weight ziplocks.
I also rotate my stock. We just got a new freezer, and since you always lose what's in the bottom, DH filled it with milk jugs of water laid on their sides, and placed a piece of cardboard on top. Now we can easily see and reach everything we have, and since it's just the 2 of us now, we still have plenty of room.
We get by with a little help from our friends
