A product tray having shrink-wrapped plastic stacked, shipped and sold on pallets due to an improved design made from a single blank of cardboard or other package material. Such improved product tray resists horizontal shifting and prevents vertical stack failures when exposed to horizontal forces during shipping. Each improved product tray supports a comparable compressive load while being composed of less material or less expensive material as compared with prior art designs. Such improved product trays may be stacked, shipped, and sold on pallets without first packaging them into boxes, and without the substantial additional labor normally required for trays made according to the prior art, at warehouse club stores and other outlets.
