A cardboard box is a three-dimensional model composed of multiple faces that are moved, stacked, folded, and surrounded to form a multi-faceted solid. In three-dimensional composition, the faces play a role in dividing space, and by cutting, rotating, and folding different parts of the faces, different emotional expressions are achieved. When displaying the relationship between the faces in a cardboard box, it is important to pay attention to the connection between the display face, sides, top, and bottom, as well as the setting of packaging information elements.
 Paperboard packaging is largely promoted and beautified by its exquisite shape and decoration to enhance the competitiveness of the product. Due to the shape and structural design of the paperbox often need to be determined by the shape characteristics of the packaged goods, so its style and type are very many, such as rectangular, square, polygonal, special-shaped paperboxes, cylindrical, etc., but its manufacturing process is essentially the same, that is, selecting materials – designing icons – manufacturing templates – stamping – assembling into boxes.
 The raw material is pulp, usually corrugated paper, which is often used to hold items and is recyclable.
 Paper product packaging is the largest category in the packaging industry. Corrugated boxes are the main form of transportation packaging, and paper boxes are widely used as sales packaging for food, medicine, electronics, and other products. With the change in transportation methods and the transformation of sales methods, the styles of corrugated boxes and paper boxes are becoming increasingly diversified. Almost every new type of non-standard corrugated box is accompanied by a set of automated equipment, and the novel design of the paper box itself has also become a means of promoting goods. The group believes that the future development of paper box packaging will be in the direction of environmental protection and economy, and there will be more innovative forms in front of us.
