[0002] The paper box is a three-dimensional modeling, which is a polyhedral body composed of the movement, accumulation, folding and surrounding of a plurality of faces. The faces in the three-dimensional structure play a role in dividing space. By cutting, rotating and folding the faces of different parts, different emotional expressions can be obtained. The relationship between the display face, the side face, the top and the bottom should be paid attention to, and the setting of the packaging information elements should also be paid attention to.

[0003] In paper box processing, film covering is needed, so a film laminating machine is needed for processing. The film laminating machine can be divided into two categories: coating type film laminating machine and pre-coating type film laminating machine.
