Impulse Sealer

Hi
I am attempting to make some home made MRE’s for long-term preparedness storage.
They will consist mainly of dried goods (pre-flavoured rice / pasta / noodles etc) plus some candy bars, tea, coffee etc.
Assuming that the shortest lifespan (sell-by date) is on the candy bar – lets say 1.5 years – how much could that lifespan be increaced if all the food is sealed into a single bag using a vacuum sealer machine? and stored at the following temps:
room temp
refrigerated
frozen
thanks in advance

You don’t really need to go to that length. Keep it in an airtight container and stick it in the freezer.
You’ll use it all up before it goes bad.
