The origin of cartons

The origin of the cartons is that after the cardboard is made, the cartons can be identified as cartons only after several processes such as paper separation, line pressing, slotting and corner cutting, printing, punching, gluing and nailing are completed.

Paperboard is a kind of board which is composed of face paper, base paper and corrugated core paper. Box board paper is used for the inner and outer sides of corrugated board. Corrugated core paper is a kind of regular and sustainable corrugated paper, which generally uses low-g paper as the core paper and high-G paper as the surface and bottom paper.

The machine of box board paper forming is the key machine. Between 1920 and 1970, our country's carton factory was always in the same face value manufacturing level.

After 1990, all carton industries gradually changed from one noodle machine manufacturing to a production line composed of multi machines and multi-functional linkage. In the previous production process, corrugated board was continuously made into cartons after entering various forming equipment or die-cutting equipment of cartons.
