Abstract
A package of a continuous strip of material includes a plurality of parallel side by side stacks each containing a length of the strip which is folded back and forth such that each folded portion of the stack is folded relative to the next portion about a line transverse to the strip and such that the side edges of the strip portions are aligned. The stacks are formed in a stepped fashion, with a series of separate layers being laid down for each stack. The package can be compressed to reduce the height of the stacks and maintained in the compressed condition by an evacuated sealed bag.
