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.
