Abstract
A stock material for use with a cushioning conversion machine is provided. The stock material includes a plurality of superimposed plies of a sheet-like material which are fan-folded into a rectangonal stack. The superimposed plies include a series of alternating folds which each create superimposed creases through the plies. The alternating folds together form a sequence of rectangular pages which are piled accordion-style one on top of the other to form the rectangonal stack.
