Abstract: A tuck label for placing on a shipping package. The tuck label includes a substrate portion and a single sheet label portion with adhesive included on a surface. The label portion further includes one or more fold lines that define upper and lower adjacent print panels, both of which can receive printable indicia. A score line is placed in the label portion to define a mount region, a printable surface region and a pull tab region. The pull tab region is disposed between the mount region and the printable surface region, and includes a pull tab with at least one layer of adhesive so that, upon folding of the label portion along the one or more fold lines, the pull tab becomes multi-layered for increased strength and durability.

Abstract: A single blank is used to make an expandable envelope construction having four side edges which can expand as the envelope construction is filled to capacity. The blank is provided with horizontal and vertical score lines and fold lines which permit the sides and bottom of the construction to collapse inwardly while the pocket enlarges in thickness and decreases in height and width. The blank has side flaps with rounded comers at the ends which are overlaid by the back panel and closure panel in an unsecured manner to maintain the envelope in a sealed condition when expanded.
