What machine?The plastic can be expensive and so is the initial purchase of the machine.
I will be experimenting with canning deer meat this year, if I can get the stuff together in time. It's not easy to find used jars, when you wait till prime canning time of the year lol.
It is quite literally, a roll of Saran Wrap that gets used before the brown paper.
This is not about vac-sealing the stuff, just a simple wrap of thin plastic to seal away the air!
Which works really well!
