We use the vacuum packing system on all of our sausage, steaks, roasts and vegetables. It doubles the amount of time in the freezer that stuff will last. When properly frozen corn on the cob tastes just as fresh a year later as it did a week later from the freezer.
There are two different types of sealers out there, the most common requires the use of a special bag, the other was found online from a place in California. Mine will seal any type of plastic bag. The other kind requires a special bag which costs about 15 cents each and when you do three to four deer a year, that cost can add up quick. This is why we use the other kind of sealer, it keeps the cost down.
