Abstract

A method of loading a stack of sheet stock material for use by a dunnage conversion machine, includes the following steps: (i) providing first and second stacks, the second stack being protected by a carrier having a central portion and longitudinally-spaced extensions that bound a central portion, the extensions and the central portion being joined along a weakened area defining a tear line, the central portion and the longitudinally-spaced extensions forming a planar bottom panel and a planar side panel, each panel extending substantially the length of the stack, and at a right angle to each other about a fold line over a bottom and an adjacent side of the stack, and one or more bale ties longitudinally inwardly of the tear lines holding the carrier to the stack; (ii) removing the extensions from the carrier; (iii) setting the second stack on top of the first stack; and (iv) removing the bale ties and the carrier, whereby an adhesive bonds the top page of the first stack to the bottom page of the second stack.
