[0002] A paper box is a three-dimensional shape, which is composed of a multi-faceted shape formed by the movement, stacking, folding and encirclement of several surfaces. The surfaces in the three-dimensional structure play the role of dividing the space in space. Cutting, rotating and folding the surfaces in different parts will produce different emotional expressions. The composition relationship of the display surface of the paper box should pay attention to the connection between the display surface, side, top and bottom, as well as the setting of packaging information elements.

[0003] Corrugated paperboard is made into corrugated boxes through die-cutting, creasing, nailing or gluing. Corrugated boxes are the most widely used packaging products, and the usage has always been the first among all kinds of packaging products. Including calcium plastic corrugated boxes. For more than half a century, corrugated boxes have gradually replaced wooden boxes and other transportation packaging containers with their superior performance and good processing performance, becoming the main force of transportation packaging. In addition to protecting goods, facilitating storage and transportation, it also plays a role in beautifying and promoting goods.
