How long will Home-Made MRE past, if vacuum sealed?

Hello I am trying to make some homemade MRE for the long storage preparation time. It will be mainly dry goods (before flavored rice / pasta / noodles, etc), plus some chocolate bars, tea, coffee, etc. Assuming that the lower life expectancy (expiry date) is for the candy bar - say 1.5 years - How could be that life increaced useful if all the food is sealed in a single bag using a vacuum sealing machine? and stored in the following temps: Room Temp chilled frozen thanks in advance

Good luck. Note that this work is stored cooked for a year before a packed.
