ABSTRACT:
A paper product may be made as a crumpled paper strip provided with a layer of coadhesive on one side to adhere opposed portions of the strip together in a strong manner to form a dunnage material. The paper product may also be made as a packaging wrap of two-ply construction with the corrugations of a corrugated ply adhered to a flat ply via a coadhesive on both plies. The paper product may also be made as small discrete elements. The apparatus for making the packaging wrap employs a pair of rolls with interengaging projections to form corrugations in a sheet of material coated with a coadhesive and guides for adhering the corrugated sheet to a flat sheet of material.
