With the rapid development of science and technology and increasingly fierce market competition, product packaging has become an important means to promote sales and enhance competitiveness. Many new technologies, new processes, and new ideas have been applied to the design, processing, and production development of packaging so that products and technologies can be combined to promote the development of packaging technology; and related technologies and related disciplines are utilized. Finally, new packaging technologies and new packaging industries were formed. The development of packaging equipment has tended towards high-speed, high-efficiency and high-quality packaging machinery; packaging materials have also emerged a new trend of development and become an active research direction, new materials can achieve very good packaging results; packaging technology is built on On top of packaging new thinking, packaging new thinking is to detach existing or existing packaging technologies and products. The new packaging technologies are embodied in the following aspects: packaging and curing technology, new cutting and molding equipment, packaging and processing technology, packaging function borrowing technology, and packaging function protection technology. With the development of packaging technology, the use of new equipment, new materials, and new technologies, the packaging industry has become a path of specialization and collectivization. China's current packaging technology and industry have been well developed and unprecedented since the founding of the People's Republic of China. However, the packaging industry in China is far from the advanced countries in the world. The main reason is that there are similarities in the packaging design. There is no prominent characteristic of the product. Many of the export products are difficult to compete with foreign products because of the packaging. It's often square, packed in boxes and packed. The author believes that the packaging design must solve the problem of the overall space shape and facade decoration of the packaging.
1) The packaging is artistic and three-dimensional. Everyone knows any one
Each three-dimensional object has a height, a width, and a thickness. This is the three-dimensional structure described in the three-dimensional structure. When a certain part of the three-dimensional structure is tilted, an irregular shape appears. This causes a three-dimensional modeling problem and how to form a three-dimensional shape. To achieve the perfect art, and achieve a harmonious unity with the packaging products. The author thinks: In the overall relationship of packaging design, can show the beauty of rhythm. This form of rhythm itself expresses a coordinated order. After watching people, I feel soft and elegant. The specific performance in the design. For example: a design of the line, to express a very smooth stretch, which reflects its rhythm. Each part of a set of shapes should also have the same or similar parts in an orderly arrangement. This sort of order can be from small to large, or from high to low, and can also be gradually changed from close to sparse. Such as: in the series of cosmetic containers modeling and packaging and decoration design, we must seize the product's overall performance characteristics, and then find out each of the respective requirements of cosmetics, to take a comprehensive consideration, so that the product's style consistent, uniform color, Form a unified style of the series, and again, emphasize contrast and coordination. In contrast, there are many aspects. In a product, there should be a comparison of the size of the image, as well as the length and width of the contrast.
The arrangement of the image before and after the level should have the first, second or third order, and there should be a narrow and wide interval change. Associated with this is the comparison of space and the comparison of density. Between the images, there must be gatherings and disperses, and there are Lords and Lords. The main part needs to be an intensive visual center, and the minor part must have appropriate echoes and connections. In addition, there should also be image music, straight contrast, and the reconciliation and contrast of the direction of movement, as well as the contrast between brightness and darkness and color warmth. These contrast relationships are handled well, and the designed packaging will be lively and varied and colorful. To reconcile, it is to compare the factors that identify the unity. The design of the various components, there is a certain link between each other play a coordination role, so that the overall coordination of the product.
2) The decoration of the packaging plane. In modern packaging design, flat decoration is also a key part of the sales of packaging products. “Decoration†is a concept in a narrow sense that is to modify and perfect the surface of an object. Its role is embellishment and attachment. It is a three-dimensional representation of the patterning of a work. The concept of decoration is broadly speaking. First, it is a widespread and universal one. The phenomenon of culture and art is not only a category of art, but also a category of culture and history. It is one of the most important information for people to understand the historical and cultural connotations of different times. Second, decoration also has sociological and aesthetic significance. It manifests itself as the act of creating beauty and the results produced by it, and it manifests social consciousness, beliefs, and values ​​through this form, that is, decoration should be the spiritual life of man and the product of man’s ideology. A strong and beautiful feeling of a person is an aesthetic activity that expresses the feelings of the beauty and is the ability and skill of the externalization of the aesthetic activity.Therefore, a cultural history is also a decoration history in a certain sense. It has several functions: aesthetic function, adjusting function, highlighting and emphasizing function, symbol and sign function.
Plane decoration mainly refers to the product itself and the outside of the box decoration of the text, pattern decoration, planar bump is called the form of two-dimensional space. In the packaging plane structure, the most basic research object is "form." Any one form can be decomposed into several units, and these units can be reassembled into new forms.
The process of recombination after this decomposition is the process of composition. The basic principle of composition is to regroup several identical or different units according to certain principles. The process of decomposition and recombination mutates the form, and the limited form is constructed into infinite combinations. The process of decomposition and combination embodies the concept of composition, and it is a way of design thinking that seeks new possibilities for modeling. In modern social packaging design, the design principles of flat facades are correctly applied to the actual product packaging. The appearance of the design product depends on the principle of three-dimensional structure plus its own understanding of the product volume, comprehensive analysis, and results. The first manuscript creation, and then use computer technology to complete. The decorative design of the packaging plane should use the principles of planar composition and color composition, earnestly comprehend the purpose, power and characteristics of the product, carry out plane combination, determine the color according to the use of the product, and perform concave and convex two-dimensional art processing on the plane. For example, Joe enhanced the design of "Mao Yan", "General" and other alcohol packaging, fully embodies the ancient Chinese wine culture and art ideas. In the appearance of ancient style and diverse.

Metal Zipper
Metal zipper zipper belongs to one of the microphones refers zipper teeth made of copper, aluminum or copper-nickel alloy material produced zipper, resin zipper and Nylon Zipper compared in terms of, more durable, and more for jeans, jackets and backpacks.
Features: Rugged, higher cost
Divided according to the size: # 3, # 4, # 5, # 7, # 8 and so on, depending on the size microphone size zipper teeth change. Because it is often used in the jeans, jackets and backpacks, so its dimensions are larger zipper.
classification:
1. TYPE: closed zipper,
Opening zipper (detachable),
Double closed end zipper (X- zipper with double slider zipper with two opposite or O- double slider two opposite), double open end zipper (Inverse open detachable)
2. Mi tooth Material: Existing material type of aluminum, brass, copper-nickel alloy, zinc alloy. Color metal microphone teeth often as needed electroplated, such as aluminum plated microphone yellow teeth, tooth-plated brass microphone white, black nickel, bronze, red bronze, gold and other colors.
Metal zipper Composition:
And other similar zippers, metal zippers composition is formed by a cloth belt, microphone teeth, slider, limit codes.
Tape: Material generally fiber belt, cotton or polyester fibers with a belt, can choose different materials depending on the application.
Mi teeth: the market for the production of metal zipper and more aluminum, brass, copper-nickel alloy, zinc alloy and other materials made of, since the color on the metal zipper teeth are plated microphone up, if improperly stored, the teeth will turn black microphone clothing and would cause pollution. For microphone tooth copper alloy is prone to oxidation, so when you save to ensure a certain degree of ventilation, do not sealed, do not save in the moisture-laden environment, if necessary, have to use the moisture-proof paper or desiccant.
Slider: metal slider respectively bronze color, red bronze plating, white, yellow-plated, black nickel, black nickel, matte silver, under normal circumstances, the color of the metal slider requires a microphone with a metal zipper teeth the same color. According to regulations, common slider parameters are:
3 # metal slider opening height of 2.1-2.2mm, mouth wide as 4.55-4.65
5 # metal slider opening height of 2.7-2.8mm, mouth wide 6.0-6.05
Limit code: divided into upper stop (front yard) and bottom dead center (post code). The main role is to prevent the upper and lower retaining slider from microphone teeth.
Note:
In the garment washing or processing time, pay attention to:
A wool knitwear after being ironed, to ensure adequate cooling can after zipper packaging, otherwise,
After the metal zipper will react with steam generating, easy to change color. Second, in the clothing trade processing, it tends to remain certain chemical reagents, then it is easy to react and metal zippers. Therefore, prior to assembly of metal zippers, leather has been the need to ensure adequate for cleaning and neutralization.
remind
Since there are different zip adaptability in different environments, so in the selection and purchase of the zipper when you choose must inform the manufacturer of the zipper on the application in which products, and manufacturers have to inform you of the fastener component requirements, such as You can be a pin detection and so on. Further, generally prohibit the use of azo dyes in the composition, as the dyed fastener after contact with body induce certain diseases.
Maintenance tips:
First, the science of using a metal zipper:
1, when the metal zipper pull, it must be close to both sides of the tooth, must be aligned to the top, then head down the track holds metal zipper pull gently, not too much force to pull.

2, when moving the metal zipper should be careful not to hem skirts or other debris caught in the metal zipper in order to avoid "crooked teeth", "belly", "off the teeth" and so on.
3, if the metal zipper astringent, not easy to pull, do not dead lift, put some wax or soap on top of a metal zipper, you can pull.
4, if the metal zipper teeth unilateral differences rope, wear loose hair, available in popular tiger clamp closed end of the metal zipper lateral gently clip, metal zipper immediately changed for the better, unilateral teeth together tight, no broken loose.
Second, to prevent metal zipper moisture, oxidation, rust and discoloration.
1, to avoid contact with the moist environment: because the metal zipper metal oxide due to the dip caused by tooth portion has a black phenomenon.
2, avoid contact with rubber band: Because rubber band itself contains sulfides, when bundled with rubber band metal zipper, metal chain teeth will have vulcanized phenomenon (black).
3, should be cleaned and dried after washing with water: because the fabric dye or residual chemicals and metal parts redox reaction, metal parts may cause discoloration.
Cause of Color Changes
a, copper alloy (copper-nickel alloy, copper, brass) made of metal zipper discoloration of reasons:
When used in the metal or hair products, metal zippers metal due to oxidation caused most of the teeth have a black phenomenon. This is because when the bleach manufacturing process of cooked skin leather woolen products agents on the process and remains in the product, the product gas can cause discoloration of the metal zipper.
Examples of chemical reactions: oxidizing bleach (H2O2) → black (CuO) or red (CuO2);
b, rubber bands bundle of metal zipper color reasons:
Rubber band itself contains sulfides, when the rubber band bundle metal zipper, metal chain teeth will have vulcanized phenomenon (black).
Chemical Reaction Example: excess gas sulfides or HS2 conditions → black [CuS]
c, contact with an acid or chromium compound causes discoloration.
Chemical Reaction Example: acidic compound and chromium compound [Cr2O3] → Black [CuO, red [CuO2] or blue [CuSO4].
