One of the more important design elements in product packaging design is: packaging design. Like other principles such as architectural design and industrial product design, the box type design and container type design of packaging are determined by their own functions, and are determined according to the nature, shape and weight of the products being packaged. The rational use of the principle of three-dimensional structure in the packaging structure of the solution is a more scientific design method.
   First, the packaging carton body design
   The carton is a three-dimensional shape, and its forming process is a multi-faceted process in which a plurality of constituent faces are moved, stacked, folded, and surrounded. The surface in the three-dimensional structure functions to divide the space in the space, cuts, rotates, and folds the surface of different parts, and the resulting surface has different emotional expressions. The plane has a smooth, smooth and simple sense; the surface has a soft, gentle, elastic sense; the circle is simple, full, square, strict, and so on... These are exactly what we need to consider when we study the shape of the carton. To the The study of polyhedrons in the three-dimensional structure consists in finding the regularity between the face and the face of a polyhedron, and exploring the relationship between the changes in the faces of the body and the strength of the material.
   For example, the joints of the surface in the carton form are usually connected by dots, lines, and face-to-face in the lid, box body and box bottom structure. Take the bottom of the box as an example: The bottom of the box is the part that bears the greatest influence among the factors such as weight, resistance to pressure, vibration, and drop, and is more suitable for surface connection. By using methods such as interlocking and locking on each side, the bottom of the box is firmly sealed and molded. This structure can pack a variety of products, mostly in small and medium-sized bottled products. In addition, the six basic geometric shapes in the polyhedron and their variants have similarities and similarities in the actual life with the complicated and varied external appearance of the commodity. The carton packaging structure should give full play to the molding characteristics of polyhedrons in the function and characteristics of the goods, and skillfully use the body language to express the characteristics of the goods and the beauty of the packaging.
   At present, many food packaging on the market, according to Plato or Archimedean definition in the polyhedron, is the basis for the formation of the outer packaging box: each side consists of a repeated shape and a combination of different shapes on each side. The more it is, the closer it is to a sphere, such as a Japanese “chocolate†wrapper, whose appearance corresponds exactly to the definition of a Plato sphere: 8 identical regular triangle cardboards are interspersed after being folded, surrounded by a positive octahedron, and sealed with a The simple and simple wire ropes cleverly connect the eight sides, and play the role of fastening function. The model is rigorously shaped, with a unique ethnic style of Japan.
   Second, the packaging container design
   The container design is also a space art. It uses various materials and processing methods to create a three-dimensional image in space. In determining a basic form, the “sculpture method†is often used as the basic one, and then the cutting or combination of shapes is performed. The positioning of the basic shape is derived from geometric shapes such as spheres, cubes, cylinders, and cones. The bottle shape of cosmetics is usually based on the shape of a cylinder, and the column structure in the three-dimensional structure is mainly reflected in the change of the column end, the change of the cylinder surface, and the change of the ridge line of the cylinder. The cutting and flexion of each part is adopted. Rotation, indentation and other techniques. Such as: "Lumei" cosmetics package design, bottle shape followed by a cylindrical shape, but in the end of the column (bottle), the cutting method to cut 4 pieces, resulting in 4 planes. The combination of the curved surface and the flat surface makes the brightness of the gold-plated aluminum cover stronger, and enhances the visual effect of contrast. It feels novel. Many perfume bottles are often cut or twisted on a square or elliptical basis to form a polygonal bottle shape, which enhances the refractive effect of the glass.
   In addition, the "simulation method" is also a design method for container modeling. That is to directly imitate a figurative form, in order to enhance the visual effect of the product, to attract consumer groups. The bionic structure in the three-dimensional structure provides a good help for us to reflect the colorful real life and enrich and improve our performance. Example: The Scotch Whisky bottle is designed as a bell because the brand name of the wine is a bell. Reached the effect of promoting product brands. The French " Harmony" liqueur bottle was designed to take on its image. It means that the wine is of a mild nature and it is pleasant to drink. Although the design of the simulation method is more concrete, but it should be the subject, reasonable, imitation of the object to strive for form beauty. Package design is also an abstract form of language expression. How to use abstract language to express the artistic appeal of packaging design also requires the aid of three-dimensional composition.
1. Vitality The forms we study are themselves in the state of being in a static state. Many of the natural forms are based on their exuberant vitality, giving people a sense of beauty, and absorbing the spirit of an expansion and extension in the natural form to be creative. Used in packaging design.
2. Movement means development, advancement, balance and other good qualities. The use of "gradient" methods to form visual temporal changes can form a "dynamic composition." In the design, it usually depends on the curve and the rotation of the body in the space.
3 , body feeling refers to the psychological feeling brought about by body mass. When designing, Guan Jian needs to deal with the different physical forms and give different psychological implications. Using local reductions, additions, turns, and buckling can all exhibit better results.
4. There are many forms of depth perception in the natural form of depth perception, which can be attractive. Depths are expressed in abstract shapes, such as: contrast and harmony, rhythm, and rhythm; the overall shape of the form, such as unity and change, symmetry, and balance can give a spiritual beauty.
