Carton introduction:

The paper box is a three-dimensional shape, which is composed of polyhedron with several faces moving, stacking, folding and enclosing. The face in stereoscopic composition plays a role in dividing space. Different parts of the face are cut, rotated and folded, and the final face has different emotional expressions.

The composition of carton display surface should pay attention to the relationship between display surface, side surface, top surface and bottom surface, and the setting of packaging information elements.

Carton packaging promotes and beautifies goods to a great extent with its exquisite shape and decoration, and improves the competitiveness of goods.

Because the shape and structural design of cartons are often determined by the shape characteristics of packaged goods, there are many styles and types, such as rectangular, square, polygonal, shaped cartons, cylindrical and so on. , but the production process is basically the same, that is, selecting materials-designing icons-making templates-stamping-assembling boxes.
