The Southern Champion Tray 1095 sheet cake and utility tray is made of clay-coated craft paperboard, which has a white exterior and a brown interior. It 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 26 x 18-1/2 x 4 in. (L x W x H), which is the perfect size for full sheet cakes.
