The cardboard box bonding machine is a machine that applies adhesive to the outer surface of the inner folding sheet or the inner surface of the outer folding sheet after folding the inner folding sheet. When folding the outer folding sheet, a mechanical device is used to apply a certain amount of pressure to the bonding area to stick the cardboard box sheets together. After the adhesive dries, the cardboard box is sealed.

A packaging cardboard box is an outer packaging container that is a collection and arrangement of packaging items that have already undergone various forms of packaging. The bottom of a regular cardboard or corrugated cardboard box is composed of four folding sheets (i.e. two inner folding sheets, also known as small sheets; two outer folding sheets, also known as large sheets or side sheets), and the folding sheets must be folded between the seals before sealing.
