There are three main methods for designing shaped folding cartons: 1, deformation design The method of deforming a folding carton by deforming the face, sides or corners of a right-angled hexahedral box is referred to as deformation design. 2, oblique line design In the right-angle hexahedron box box, box cover or box bottom position design oblique indentation, so that the box shape changes, as shown in Figure 1. 3, curve design In the right-angled hexahedral box, the curve indentation is designed at the position of the box, box cover or box bottom, and a shaped paper box is obtained, as shown in FIG. 2 .
