I have seen these vacuum lock baggie system sold at Sams and Walmart. You
put your stuff inside hook up the vacuum pump, suck out the air, and heat
seal the ends. Primarily used for food storage but can be used for anything
including clothing to reduce volume.

If you use it for engine parts I am not sure if I would use it for food
afterwards.

Looking for good method to pack long term spare parts on long term
cruise - like a spare alternator, starter, diesel injector pump,
expensive things

I have used ziplock bags for parts and tupperware for my tools for 7 to
ten
years without anything to keep it dry. It has worked good. Tools and parts
still don't have any rust. You could use some kind of cloth bag in the
ziplock
bag for heave stuf, or a tupperware container if you can find one the
right
size.
