Accordion-folded paper sheet packing material

摘要

Packing material (14) and method in which a sheet of paper stock (16) is folded in opposite directions along alternative parallel lines (17,18) to form a series of ridges (19) and valleys (21), cuts (23) are made in the stock (16) at intervals spaced along the ridges (19), and sections of the stock (16) adjacent to the cuts (23) are folded in a reverse direction along the fold lines at the ridges (19) to form downwardly extending pleats (26) beneath the ridges (19). The material (14) can be crumpled for use as a dunnage material or wrapped about an item to be protected. In one disclosed embodiment, the material (14) can be compressed for shipping and storage and expanded for use. In another, which is particularly suitable for use as a protective wrap, the folded stock (16) is affixed to a backing sheet.
