I contacted someone from the powerbook list who sent the following info. It appears
I'm on the right track for successful storing of old laptops.
I have to say that I'm very appreciative of all the help and positive thoughts
coming from contributors to my question. It's amazing how we make each other think,
produce a response, and then improve upon it with help from another. Thanks to
everyone who's been helping.

Chuck,
I don't follow this list, but I agree with Dan if you want a vapor
proof
bag, you need a metalized bag, polypropolyne and most other flexable
plastics, absorb water and outgas both into the air and the bag.
Vacuum
sealing with the right bag, desiccant and a VCI inhibitor would do the
trick. A company I have delt with is CORTEC Corp., 4119 White Bear
Parkway,
St. Paul, MN 55110, Phone 612-429-1100. As an aside, if the desiccant
bag
is sized properly, and the item double bagged leakage is not a
significant
issue over 10 years or so, most spare parts used in the submarine
service
are packaged this way, with a indicator card so the item can be
repackaged
when necessary.
