The carton is a three-dimensional shape, and its unfolding process is a process in which a plurality of surfaces are moved, stacked, folded, and surrounded by a polyhedron. The surface in the three-dimensional structure functions to divide the space in the space, cuts, rotates, and folds the surfaces of different parts, and the resulting surface has different emotional expressions. The plane has a flat, smooth and concise feel. The surface is soft, gentle and elastic. The simplicity of the circle, the fullness, the strictness of the party, and the dignity... These are precisely the things we must consider when we study the structure of the carton.
The study of polyhedrons in the three-dimensional structure is to find the regularity between the face and the face of the polyhedron, and to explore the relationship between the change of the face and the strength of the material. For example, surface joints are usually present in the box cover, box body and box bottom structure in three ways: point connection, wire connection, and face contact. Take the bottom of the box as an example. The bottom of the box is the part that can bear the weight, and has the greatest impact on factors such as resistance to pressure, vibration, and drop. It is more suitable for the surface connection. It uses various methods such as interlocking and locking to make the bottom of the box securely. Sealing molding. This structure can package a wide variety of products, mostly small and medium-sized bottled products.
In addition, the six basic geometric shapes and their variants in the polyhedron have similarities and similarities in the actual life and the complex 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, the molding of the outer box is based on the definition of Plato or Archimedes in the polyhedron, and each side composed of repeated shapes adopts a combination of different shapes: the more faces are combined The closer to the sphere. Such as Japan's "chocolate" packaging, its appearance just corresponds to the definition of the Plato sphere, from the same regular triangle cardboard folded after interpenetration, surrounded by - a positive octahedron, the closure using a simple and simple wire clever The ground connects eight sides and plays a sturdy function with a Japanese style.
Packaging 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 a static state, and many of them are aesthetically pleasing to people with their vitality. We should absorb the spirit of expansion and extension in the natural form and creatively apply it to packaging design.
2. Dynamic—meaning good qualities such as development, advancement, and balance. The “gradation†method is used to form visual spatial changes. The formation of “dynamic components†is usually based on the curve and the rotation of the body in space.
3. Volumetric sensation - refers to the psychological sensation that body weight brings to people. The key to designing is to deal with the modalities of the same body mass in different ways to express different psychological cues. The use of local deficiencies, addition, reversal, and buckling can all Reflect better results.
4. Depth perception - There are many forms of depth perception in the natural form that can lead people to victory, with abstract shapes to reflect depth, such as: contrast and harmony, rhythm and rhythm.
