Abstract
A bale of stock packaging material includes a continuous tube of paperboard material, the continuous tube of paperboard material being flattened and folded back and forth on itself into a fan-folded bale. The continuous tube of paperboard can be a single piece of paperboard with two opposed edges that are folded to overlap with each other. The paperboard material can include a corrugated layer. The opposed edges can be adhered together to form a single seam that runs lengthwise along the continuous tube of paperboard. The adhesive can be applied between the two edges which can join to form the single seam.
