The carton is a three-dimensional shape, which is composed of a polyhedron formed by moving, stacking, folding, and surrounding several surfaces. The faces in the three-dimensional composition play the role of dividing the space in the space. If the faces in different parts are cut, rotated, and folded, the obtained faces have different emotional expressions. The composition relationship of the carton display surface should pay attention to the connection relationship between the display surface, the side, the top and the bottom, and the setting of the packaging information elements.

Carton packaging to a large extent promotes and beautifies products with its exquisite shape and decoration, and improves the competitiveness of products. Since the shape and structural design of the carton are often determined by the shape and characteristics of the packaged goods, there are many styles and types, such as rectangle, square, polygon, special-shaped carton, cylinder, etc., but the manufacturing process is basically the same, that is, select material - design icon - manufacture template - stamping - join into box.

Paper product packaging is the most used type of packaging industrial products. Cartons are the most important form of transportation packaging, and cartons are widely used as sales packaging for various products such as food, medicine, and electronics. With the changes in transportation methods and sales methods, the styles of cartons and boxes are becoming more and more diverse. Almost every new type of non-standard cartons is accompanied by a set of automated equipment, and the novel cartons themselves have also become means of product promotion. In the future, carton packaging will develop in the direction of environmental protection and economy, and there will be more innovative forms in front of us.
