Modern packaging should meet various requirements in terms of shape, not only to have a sense of lightness in hand, but also to have a sense of the times, both economical and beautiful. It can be seen that the shape design is not indispensable for packaging production, sales needs, and consumer psychology. The psychological impact of surface design on people is also considerable.
　　The shape of packaging is generally angular and round, especially for quadrangular boxes (boxes) and round cans (bottles). No matter how the shape changes, it must be in harmony with the content, price, material, and product performance, and become a complete art body.
　　The style of packaging is ever-changing, and the packaging containers made of different packaging materials have different styles; There are also different styles of packaging containers made of the same packaging materials, such as open box, open window, folding, etc.
　　The structure and function of the packaging must consider the following factors: the physical form of the packaged object (such as solid, liquid or gas), the convenience of sale and use, whether the packaged item needs to be displayed, the special requirements of the display effect, etc.
