Stock material units that may be used in a dunnage conversion machine. For example, stock material units include sheet material that may be fed into the dunnage conversion machine and may be converted thereby into dunnage. The stock material unit includes a continuous sheet of material including a tapered sheet section defined by a plurality of slanted folds and positioned adjacent to at least one face of the three-dimensional body, and a splice member. The splice member includes a base having a first side attached to a portion of the continuous sheet of foldable material that is positioned adjacent to the tapered sheet section and has an opposite, second side. The splice member also includes a connector that has a first portion non-removably attached to the tapered sheet section and a second portion removably attached to at least a portion of the second side of the base.
