Bales are wrapped very tightly and very little air is trapped inside. This ensures that the fermentation of the grass (the process by which it becomes silage) is carried out in the correct conditions. If air gets into the wrapped silage it can spoil and become unpalatable to livestock. Big bales can be stored in any convenient location where there is hard standing. Often this is adjoining a small barn where stock will be overwintered.
