Abstract: A method that includes the steps of (i) attaching a leading portion of a supply of stock material to a trailing portion of a preceding supply of stock material by means of a mechanical fastener, an electromagnetic field, electrostatic charges, or an activatable bonding agent, and (ii) converting the stock material into a relatively less dense dunnage product. The attaching step may include (a) embossing, punching, stitching, stapling, riveting, clipping, snapping, buttoning, attaching with male and female interlocking devices or hook-and-loop fasteners, (b) integrating one or more elements into the stock material to provide a stock material with magnetic or magnetizable material in the leading or trailing portion, (c) imparting opposing and attractive magnetic charges in respective leading and trailing portions, (d) inducing an electrostatic charge or a magnetic field in at least one of the leading and trailing portions, and/or (e) activating a bonding agent.
