All kinds of geometry, if the same volume, the ball shape of minimal surface area; for prism, the cube surface area than the rectangular surface area is small; for the cylinder, when the bottom surface of the cylinder is equal to the high park when the diameter of the minimum surface area.
Excellent packaging design should follow the following principles:
(1) combined with the characteristics of the product, make full use of the law of formal beauty;
(2) to adapt to the market demand, make accurate market positioning, create brand personality;

(4) draw inspiration from nature and use simulation method to design the appearance of packaging;
(5) full consideration of environmental and ergonomic factors;
