1. A packaging blank comprising:
a first layer; and
a second layer on top of the first layer,
wherein the first layer is laterally offset from the second layer such that a first portion of a top surface of the first layer is exposed at a first side of the blank and such that a second portion of an under surface of the second layer is exposed at a second side of the blank,
wherein each of the first and second portions comprises a line of perforations, wherein each of the line of perforations extends longitudinally along the length of the blank;
wherein the line of perforations on the first portion and the line of perforations on the second portion are positioned on the first and second portions such that when the blank is folded the exposed top surface of the first portion is configured to be affixed to an outer surface of the second layer, the exposed under surface of the second portion is configured to be affixed to an inner surface of the first layer and the first and second lines of perforations are substantially aligned with an internal space between the lines of perforations;
wherein a second side inner edge of the second layer is configured to be sandwiched between the first layer and the first portion, a first side inner edge of the first layer is configured to be sandwiched between the second layer and the second portion, and the first side inner edge of the first layer is configured to be spaced from the second side inner edge of the second layer, thereby creating an enclosed space between the first and second side inner edges and a section of the first and second portions, wherein the enclosed space provides the internal space between the lines of perforations.
