at the time of vacuum sealing the box did the vacuuming also suck
all the moisture of the cigars and the box or just out of the air?
Out of he cigars.
Science you can [almost] do at home:
* Moisten a sponge or paper towel to the point of "pretty darned
* Put it in a bell jar.
* Pump out as much air as your little vacuum pump is capable of
* Wait 5 minutes.
* Release the valve, letting the air back in.
* Inspect the sponge/paper-towel.
NOTE that you will find it quite dry.
I did your experiment with a Foodsaver vacuum packer. ?The unit
came with polycarbonate cannisters of various sizes for storing
bulk material. ?The lid of each cannister has a suck port and a
relief valve. ?
I moistened a paper towel with tap water and wrang it out until it
was wet but not dripping. ?It was then lightly crumpled into the 25
oz cannister (4" in diameter and 5-7/8" high). ?The vacuum pump was
attached and allowed to run on the "cannister" cycle. ?The towel
was allowed to reside in the cannister for 5 minutes post suck,
then the relief valve was pressed, the vacuum was relieved, the lid
removed, and the towel examined.
It was as wet as when it went in.

True, with a closed system as you find in the food-saver-jar, but
vacuum wraps vary a lot! Many are semi-permeable materials, some are
not. Some systems (checked w/ my Physics prof) .... however, it is
almost impossible to suck out the excess air without sucking out a
of the moisture. In fact, if the vacuum is good enough, you can
easily create (as Misc said) a freeze dried product with no freezing.
The Foodsaver system is kinda cool for many applications, but for a
true visual, do not use the jar ... use the bag. You can suck the
life out of bread with that machine (have been there and done that).
Alex's query is more in the vacuumed out baggie than the canister -
just a bit too much suction squashes the box, presses the 'gar, and
could quickly lead to problems depending on the film used. JMHO ;-)
I do have a Physicist and a Physical Chemist who will back me up.
For back ups, I generally rely on my IT guys.
