The Southern Champion Tray 1019 donut tray is made of clay-coated kraft paperboard, which is white on the outside and brown on the inside and can be used as a 2-piece box or 1-piece tray. Paperboard is thicker and more rigid than paper, is suitable for holding baked goods, and can be recycled or composted. If used as a box, the telescoping top slides down onto the box and fully overlaps it to help secure its contents. The lock corners facilitate assembly and enable the tray to be folded flat for storage or transport.
