In years past I've used a food grade plastic bucket for my sauerkraut. But, it's old, and I'm afraid that it might not be up to the task anymore.
So, I went looking for another 3.5 gallon food grade plastic bucket. Boy are those things spendy... as in $30 or more for one.
But, while looking, I came across food grade heavy duty bucket liners... The material says they're good for food storage or for brining, etc. I figure making sauerkraut is kind of like brining, so I'm going to give them a try.
$10 for a roll of 24 for the 5 gallon size.
I'll stop and get a Home Depot 5 gallon plastic bucket to hold everything.
The worst that happens is that the bag springs a leak, so I'll need to be gentle with them.
