One sour note with the collapsible jugs, especially the bellows type is the plastic is slightly permeable to oxygen and for long term storage is less than ideal. Also I've noted complaints about the pleats cracking when the jugs get a bit on the old side.
As a side note some buddies of mine used to play with the dry ice putting it into a soda bottle with some water and capping it. The bottle was placed on the ground and everyone left the vicinity in a grreat hurry to watch from a safe distance as the jug exploded with enough force to take all the grass off the spot the bottle occupied.
