/ 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 strip is continuous through each stack and is connected by a splice from the end of one stack to beginning of the next stack. The package can be compressed to reduce the height of the stacks and maintained in the compressed condition by an evacuated sealed bag. The package can have the stacks vertical or horizontal. The stacks are connected by a spliced portion so that the strip is continuous through the package. When the stacks are horizontal, the spliced portions are vertical and coplanar with the strips and at alternate ends. When the stacks are vertical, the spliced portions extend from the bottom to the top at one end of the stack.
