I too seal everything that goes in the freezer...
Make sure its at least tapped dry with a paper towel before sealing...juice in the seal doesn't melt the plastic too good and the seal will not hold !!
I even freeze tomato sauce with it...Freeze in tuperware first...take it out then into a bag ! works like a champ !!
And like NJ Bob said ...mark everything...I hate mystery meat in the freezer !!!
Just wish the bags were a little cheaper ...can buy online to save a couple of bucks...
