Abstract
An improved expandable slit-sheet stock material is configured to aid in temporarily restricting opening of a plurality of slits of the slit-sheet stock material, such as during winding of the unexpanded stock material or during expansion of the stock material. Each slit of the plurality of slits includes one or more un-slit reinforcement portions, such as reinforcement ties, extending fully between opposite longitudinal sides of the slit, and disposed between opposed transverse endpoints of the slit. The reinforcement ties minimize or prevent tearing of the stock material during the winding or expansion. A dunnage conversion system for expanding the slit-sheet stock material includes an expander having a pair of opposed rollers. The rollers engage the stock material to effect breaking of the un-slit reinforcement portions and expansion of the slit-sheet stock material.
