Good to hear from you,
A thorough simple taping would probably work. However, it is much more difficult 
to be confident that employees are taping properly. Heat sealing, as I indicated 
is easy and the sealing equipment is only @$200-$300. Sometimes employees are 
more responsible when they know management is serious. Actually, you could use a 
"Seal-a-Meal" sealing machine. However, I would be embarrased to tell that to 
customers or management.

Hi,

According to content on some sites simple taping might be OK and heat seal not 
required. 


I wonder how moisture diffusion through an incomplete tape seal and a bend 
compares to bag surface diffusion.

Joyce Koo recommended a dry box.  I agree that that is recommended, especially 
for short term use such as you've used some of the components and you will use 
the rest in a few days to a few weeks.  However, if you need longer term storage 
I recommend purchasing moisture barrier bags, desiccant and moisture indicator 
cards.  They're relatively inexpensive.  You would need a heat sealer ($200-$300 
and simple to use) I would not worry about vacuuming the bag, it's probably not 
worth the effort.  The formula for how much desiccant to use depends on what 
desiccant is used.  For example you might take  look at: 

http://texastechnologies.com/moisture-control/desiccant/silica-gel/packaged/sorb-it-silica-gel-unit-size.htm

for one example.  I have no investment in that company, it's just a reference to 
an example.

Good luck
