Does anyone know if a stainless steel cannister with steel or acrylic snap-lock lid and silicone ring is good (with O2 absorber) for multi-year food storage---as good as, say, a heat seal on a mylar bag? I'm wondering if a pressure seal is as good as a heat seal for keeping out the atmosphere for at least 6-9 years. If so, I am thinking about using the cannisters for storage of smaller amounts of food.
For that matter, would using a basic mason jar (snap or screw lid) with an O2 absorber be good for that long a time period? Would some kind of a coating like wax or silicone sealant around outside area help seal integrity?
I guess I like the idea of reusing the jars v. using heat seals on the mylar bags only once or maybe a few times if I could figure out how to preserve some of the heat-seal area for re-seals after the first opening
Thanks in advance for informed replies.
