A flexible, cushioning dunnage product producible on a converter mechanism from a roll of sheet-like stock material, such as biodegradable paper. As the stock material is pulled off the roll by the converter, the edges of the stock material are rolled inwardly to form pillow-like portions which are urged by the converter mechanism laterally inwardly with respect to one another into confronting abutting relation, with the pillow-like portions being then connected together along their engaged abutting sides by in the preferred embodiment, transversely extending coined sections extending transversely of the product and defining a generally central connecting portion running in a direction lengthwise of the product. The lateral, spaced pillow-like portions possess considerable resiliency and thickness as compared to the coined central connecting portion, and perforations are provided in the connecting portion to aid the overlapped coined sections in preventing opening up or separation of the connecting portion, and thus such perforations aid in maintaining the pad-like form of the product for packaging or packing.

A cushioning dunnage product comprising a flexible pad-like article for use in packaging or the like, formed from a web or sheet of stock material with the lateral edges of the web or sheet having been generally loosely rolled inwardly and forming crumpled pillow-like portions defining the lateral extremities of said product, and means connecting the rolled confronting edges of the pillow-like portions together along a central connecting portion of said product lengthwise thereof, the last mentioned means comprising transversely extending coined portions of said confronting edges, the latter being in generally overlapped relation at said central connecting portion, said laterally arranged pillow-like portions of said article possessing considerable resiliency as compared to said connecting portion, said coined portions including valley sections and rise sections, each of said pillow-like portions being of a substantially greater thickness than said central connecting portion, and characterized by said valley sections of said central connecting portion including perforations therein extending into said connecting portion from exteriorly thereof generally perpendicularly to a generally horizontal plane passing through the lengthwise axis of said connecting portion and aiding said coined portions in maintaining the product in its pad-like form, said perforations are defined by edges of the perforated stock material layers into which a respective perforation extends, said edges being oriented into pressured overlap with respect to one another creating a substantial holding together for resisting separation of the coined overlapped edges of the pillow-like portions of the product.
