In a previous life I used to repair computer terminals. They would come
in boxes that had been shot with expanding foam. Kind of like putting
the terminal in a plastic wrapping, shoot foam in the bottom of the box,
set plastic covered terminal in, shoot more foam to fill... Never saw
anything damaged in shipment that was done that way. It wouldn't stop a
forklift stab but worked good for dropping and crushing troubles.

Not sure how far you would get with the spray foam in a can used for
sealing air leaks around windows and doors. But if you could buy it
cheap enough it may be worth trying...

Not very far. you'd want the non-expanding foam, lest you come back
and find your box exploded and your product embedded in a mass of
foam. BTDT.

You might look at this

for larger quantities, you might want to look at the true
foam-in-place kits. It's a two part system that mixes in a gun and
foams immediately to the finished size. What Leon was talking about
above. It is available anywhere from 55 gallon drums of the
components to a low volume kit where the two parts come in 50 lb
refrigerant cans. I thought Uline sold the latter but I could not
find it just now.
