The surfaces in the three-dimensional structure play a role of dividing the space in the space, and the surfaces at different parts are cut, rotated and folded, so that the obtained surfaces have different emotion representations. The carton display surface is formed by paying attention to the connection relationship of the display surface, the side surface, the top and the bottom and the arrangement of the packaging information elements. The carton package is used for propagandizing and beautifying commodities by virtue of exquisite modeling and decoration to a great extent, and the competitiveness of the commodities is improved.
