Vacum Sealed bags for your boxes... good or bad?

As some of you know some companies ship there boxes in "food saver" like bags.. i was wondering if this would be okay as a long term storage for them- inside a humidor. My problem is beetles, i had to throw away 5-6 boxes and some- in the same shipment are beetle free... 6 months later. theyve been frozen and thawed and refrozen etc but im still scared so these would be the boxes i keep in a vacum sealed bag. I know it locks out humidity but it also locks whats i there... in.

So what do you think should i vacum seal them in bags and stick them in the cabinets or.... consider another option.

thanks for your help! cheers!
