3.2 Packaging Design of Waste Materials
Japan and other countries have developed new papermaking technologies that use waste paper and bagasse as raw materials, and have designed and manufactured packaging such as lunch boxes and tableware. They used 1 ton of waste paper to re-produce 800 kg of new paper, thus saving 4m3 of wood, 400kg of soda ash, 400kg of standard coal, 5000kW of electricity, and 470 tons of water, which greatly reduced the cost of papermaking, drastically reduced the cost of packaging, and reduced environmental pollution. Almond shells were used. Coconut shells, walnut shells and other raw materials are crushed and then mixed with natural or synthetic resins, and then pressed or injected to form imitation wood materials. They have good thermoplasticity, and they are elegant in appearance and feel very good. They are suitable for high-grade products. Aspects of packaging. Waste materials such as daily newspapers can be designed into bags, and newspapers in the old days will generate new value.
Figure 2 shows a paper-shaped package designed using discarded paper materials. See Figure 2.
3.3 Structural design of packaging
The structural design of the packaging form is an important part of the green design of the packaging design. Optimize the packaging structure, reduce packaging consumption, avoid excess packaging, and reduce the amount of packaging. China is a country with a shortage of resources. "Waste" causes the loss of resources and causes environmental pollution. Therefore, it is necessary to economize on the use of packaging materials, rationally design the packaging structure, not to expand the packaging volume too much to increase the added value of products, and blindly increase the sales price of goods. The cumbersome packaging waste will cause tremendous pressure on the entire society. Strive to streamline packaging and rationalize packaging, especially under the conditions of market economy, to prevent excessive packaging and exaggerated packaging, fully consider the lightness of packaging materials, and explore the thinning and aesthetics of packaging containers. For example, a standardized container transport and packaging integrated packaging method can greatly save packaging materials and reduce waste. In order to extend the service life of the packaging, special packaging features of the product can be designed, which can be used for collection, art appreciation or home decoration after use. Such as the unique shape of the bottle used as a vase.
Eco Pac drink packaging designed by a Japanese designer consists of a 100% recyclable cardboard box and a bag used to hold the beverage in the box, which is the liner bag box design. The main reason is to make it easy for people to separate the cartons from the bags and handle them easily when they are recycled. The Japanese drink Jakutt Health Drink uses a specially designed cup-shaped container with a bottom tear-off. After tearing the bottom, one can easily flatten the container for recycling.
3.4 Packaging Design
The packaging design is a visual element of the green performance of the packaging design. The surface decoration design of the packaging can not only promote the goods, but also extend the life cycle of the packaging through the surface decoration design. The packaging with flat design, low artistic quality and little interest will shorten the use cycle and increase the load on the urban environment. "KFC" packaging is very interesting, using some interesting cartoon styling to attract consumption, not only to win the hearts of children, adults like it, after the packaging can be used for collection.
Therefore, the “package of decorative puzzles of a series of puzzles†can be designed. After the use of the packaging, a series of beautifully decorated packaging can form a beautiful wall-hanging work, which not only serves the promotion of the goods but also decorates the family. Bring new life to waste packaging and reduce the pollution of packaging waste.
3.5 Online Packaging Design
The online packaging design is a paperless design and is a new idea for improving the green performance of packaging design. With the rapid development of online trade, the concept of packaging has been further expanded - online packaging is the packaging of products sold on the Internet in accordance with the size and other characteristics of the physical product. The packaging design for online products enables consumers to come in contact with the product packaging while also being exposed to online products. Reducing environmental pollution and realizing “paperless marketing†is an important advantage of online marketing. It reduces the number of actual shipping samples and reduces the cost of trade. It fundamentally avoids the product backlog caused by blind production of packaging that is not suitable for market demand. The realization of the “zero inventory†of packaging products is possible, thereby reducing waste of resources and environmental pollution.
Through the green performance research of packaging design, it seeks a new design idea for packaging designers to harmonize with the environment and nature, enabling packaging design to sublimate from a low-level design model that simply meets human needs to the coordination of human and nature. The symbiotic and complementary realm.
