We had custom expanding foam packing(InstaPak) at my TEK field
offices,and there always was the possibility of foam sticking to the
item,permanently ruining it,or too much foam crushing the item upon
expansion,or it squirting out any opening in the box,or splitting the
box.It's messy stuff to work with.

My 10" Dob telescope (pretty big) was wrapped in plastic with the foam
on the outside.

Soemtimes the foam found it's way through a tear or missed opening in the
plastic and it sticks REALLY good to things,nearly impossible to remove
without damage to the item.

The scope tube would be easy to crush if too much foam was used.

We occasionally received bad batches of foam components(2-part foam),and
the foam would not expand immediately as it should,and we had a hard time
with it,putting too much foam into the boxes and then it would begin
expanding uncontrollably.It made terrible messes.
