Question on Canning Jars and Lids
 

I bought a bunch of canning jars and extra lids that I want to stockpile/store
in case things go really south.
I have the extra lids packed in plastic zip lock bags with as much of the
air evacuated as possible.
The Jars have lids on them.
Can I just leave the lids on the jars ?
How long will the lids that are on the jars remain usable?
Should I take the lids off the jars?
Is there a better way to store the lids?
How long can you store the lids and still use them?
I am worried about the sealant compound oxidizing and rendering the lids unusable.
Thanks in advance for any input.

Re: Question on Canning Jars and Lids
 

I buy lids in bulk, and pack the regular size in wide-mouth pint jars. The wide-mouth lids go into mylar bags. Both jars and bags are then vacuum sealed, and stored in a cool, dark place.

I've used lids that had been kicking around in their original cardboard cartons for ten years: and had no problems. I expect the vacuum-packed ones will be good long after I'm gone.
