A self-contained continuous PDQ package system is provided for shipment and display of products. The PDQ package includes four adjacent sections of preferably corrugated material each with an inner facing and an outer facing surface, with a cut out within the bottom flap panel. Within the cut out, there is a section where an adhesive is placed adhering the inner facing portion of body panel and the inner facing of a section of bottom of the outer panel flap and adjacent mid-section panel. The self-contained continuous PDQ package system also provides an erectable reinforced shoulder to facilitate display of products in a stack of cartons.

A reinforced sidewall for a container carton for shipment and display of products. The reinforced sidewall includes an interior sidewall, an outer sidewall, and a bottom panel that are interconnected for reinforcement of the container sidewall. Some embodiments include a shoulder structure for supporting a container placed atop the container that is automatically deployed when the outer sidewall and the interior sidewall are moved to an upright position relative to the bottom panel. Other embodiments include a shoulder brace that is automatically deployed to support the shoulder in a cantilevered relation with the interior sidewall. A stab tab is also configured to automatically protrude from the top surface of the shoulder. The stab tab is configured to be received in a recess in a superjacent container for indexed stacking of the containers.

A retail-ready container includes internal corner supports. The container is erected from a preassembly formed from a single blank. The blank includes a side panel, a bottom panel, and an auxiliary panel. Each of the side panel and the auxiliary panel include a plurality of sections connected by respective fold lines. The auxiliary panel is folded against the side panel and sections of the auxiliary panel are adhered to corresponding sections of the side panel. Fold lines of the side panel are laterally offset from fold lines of the auxiliary panel so that unfolding of the preassembly yields the container with internal corner supports.

A corrugated plastic box and a method for manufacturing a corrugated plastic box from a blank are provided. The method includes the steps of forming rounded edge seals on the perimeter edges of the blank, pre-sealing portions of the blank—including providing air vents to allow trapped air to escape during the pre-sealing process—to form a plurality of areas in which major and minor flap slots and a glue tab are desired, ultrasonically scoring the blank to form a plurality of flap score lines, and cutting the blank through the plurality of pre-sealed flap slots and glue tab, leaving a sealed edge.

Embodiments of a reusable stackable shipping box are provided herein. The reusable stackable shipping box may be reused and cleaned without causing harm to the integrity of the box. In addition, the box is slightly tapered in shape such that the box may be stacked upon and within other boxes for ease in shipping and organization.
