A carton box is a container made of paperboard, liquid packaging board, or corrugated fiberboard used for packaging, storing, and shipping products. It typically consists of one or more layers of paper, including a wavy, fluted 'medium' sandwiched between flat 'linerboard' layers, which provides strength and durability. Common types include folding cartons for consumer goods and strong, double- or triple-wall corrugated boxes for shipping.
