A cardboard box is a three-dimensional shape made of pulp, usually corrugated paper, which is often used to store items and can be recycled and reused. A cardboard box is made up of polyhedra formed by moving, folding, stacking, and surrounding several faces. The faces in three-dimensional composition play a role in dividing space. By cutting, rotating, and folding the faces in different parts, the resulting faces have different emotional expressions. The composition relationship of the paper box display surface should pay attention to the connection between the display surface, measuring surface, top and bottom, as well as the setting of packaging information elements.

The cardboard boxes of cardboard packaging manufacturers are largely decorated to make the boxes look more exquisite, in order to promote and beautify the products and enhance their competitiveness. Due to the fact that the shape and structural design of paper boxes are often determined by the shape characteristics of the packaged goods, there are many styles and types, including rectangular, square, polygonal, irregular paper boxes, cylindrical, etc. However, their manufacturing process is basically the same, that is, selecting materials - design drawings - manufacturing templates - stamping - joining into a box.
