hI!
Regadring the packing, I do not know if it this is the case, but for a product we manufactured once, there were 3M "instant" packing products that were a tiny bag with two compartments filled with two chemicals inside. When you need to pack something you just break a couple of bridges between them and mixed them by hand. Than you place it into the box, your instrument inside, another on the top and the thing grows as a foam inside the bags taking the shape of the instrument.
No machine needed...
