I have a source for getting food grade 5 gallon pails, but is there some way I can vacuum pack the bulk food I store in them without having to vacuum pack the food in bags first before storing it in the bucket?
My pails were factor sealed back in 1999 (for y2k). I keep them not being sure whether the contents are of any value anymore. Got maybe 8 of them still.
Don’t have the $$$ now to buy anymore.
You can use mylar liners. Regular plastic is porous and does not keep out air.
Place the liner in the bucket, fill with wheat, rice, etc., place some oxygen absorbers on top, heat seal the mylar bag using an iron. Wait until the next day to pound down the lids, because the oxy absorbers will make the liners contract; you don't want the sides of the bucket to suck in.
