If you have a food grade bucket is it necessary to use a mylar bag?
It is not necessary to use a bylar bag within a food grade bucket, but the use of one provides an additional level of protection. That way you are ensuring that your food storage investment is kept in the best possible shape and stays that way until you need it. The plastic buckets are slightly porous and will allow some air transfer – the use of mylar bags will cut that O2 transfer down to almost nothing.
