Chapter 10: Packaging Styles
A basic type of folding carton is the tray, a relatively shallow carton with a bottom hinged to a wide side and end walls. The sides and ends are connected by a flap, hook, locking tab, or lock that can be glued or assembled without glue. Tray cartons can also consist of two pieces, one slightly larger than the other, forming the base and cover of a two-piece telescoping box. Trays are often used for baked goods, cigarettes, for food service items, and as pizza carryout containers.
