Should I reseal Mylar bags?

by Rccr

I just started using Mylar bags and buckets in my food storage plan. Most of the bags suck down to a crinkled mass with no visible air left in them,but there are some that still had a small amount of air left after sitting over night. Like a puffiness to the top of the bag. Should I reseal those in question or is this a normal thing with items like oats, flour, pasta etc. ?


There should not be any puffiness in the top of the Mylar bag after sitting overnight. You may need to reseal and use new oxygen absorbers. It's difficult for me to tell you for sure without seeing them, however.
