Claim:
A method for baling sheets of material comprising the steps of first, obtaining a plurality of sheets of material, second, corrugating more than one of the plurality of sheets of material, third, deforming the plurality of sheets of material, fourth, stacking the plurality of sheets of material together, and fifth, binding the plurality of sheets of material together using a plurality of holding straps to create a bale of the plurality of sheets of material, where the plurality of sheets comprise both flat sheets and the more than one corrugated sheets, where each of the plurality of sheets has a left side, right side, front side, back side, top, and bottom, where the plurality of sheets of material are stacked on top of each other to form a stack of sheets of material, where there is a sheet of material on top, a sheet of material on bottom, and sheets of material in between the top sheet of material and the bottom sheet of material, where the plurality of holding straps secure the plurality of sheets together to form the bale of stacked sheets of material, where the holding straps travel over the top of the top sheet of material, the bottom of the bottom sheet of material, and around opposing sides of all of the sheets of material, where at least one of the plurality of holding straps travels over deformations in each of the plurality of sheets of material, where there are deformations on opposite sides of each sheet of material such that if there is a deformation on the left side, there is a deformation on the right side and if there is a deformation on the front side, there is a deformation on the back side, where the width of each deformation is at least as wide as the width of a holding strap, where the deformations decrease the width of the sheet of material at the location of the deformation such that the perimeter that a holding strap must travel is less if it travels over the deformations than if it does not travel over the deformations thereby laterally restricting the movement of the holding straps.
