The Southern Champion Tray 1050 sheet cake and utility tray is made of clay-coated craft 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. The clay-coated exterior can be printed with a logo or a business name. 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. The tray measures 28 x 20 x 4 (L x W x H), which is a great size for larger full sheet cakes and other baked goods.
