I have a hand-held battery-operated vacuum sealer that uses special bags with a round valve on the corner where the air is sucked out. The largest bags I can find for it are one gallon size. In order to vacuum seal an 8 pound wheel of cheese, I have to cut it in half. So I went back to waxing. Is there some other system of vacuum packing that allows for larger size bags? For me, the waxing has worked out very well. Very few wheels end up with mold under the wax and the 5 pound blocks of wax on cheesemaking.com for $20 plus shipping will wax a lot of cheese.
