Analysis of green packaging design strategy (below)

Third, the choice of materials in green packaging design

In the early stages of industrialization, the impact of materials on the environment was seldom considered, but the choice of materials in the green packaging design is crucial. It not only determines the degree of product damage to the environment, but also determines the recyclability of the product. It is a complicated task to select appropriate materials for the design of packaging products so that they can meet the requirements of sustainable production as much as possible. It is also a process that comprehensively considers the properties of materials, environmental factors and knowledge in the field. Therefore, designers are deeply Detailed and detailed understanding and mastering of packaging materials with environmental protection and applied in green packaging design practices to minimize the pollution of materials, maintain the ecological balance of the natural environment and social environment, and also promote the use of earth resources by the packaging industry. Type to recycling regeneration.

1. Material properties and applications

The characteristics of the material often determine the effectiveness of the material energy in the production process and use. Green packaging materials should use low-energy, low-cost, less-polluting materials, and the selected materials are easy to process, with no pollution or less pollution during processing. For example, self-destructive plastics in self-destructive materials designed and researched by China's scientific research institutes for environmental protection include the addition of special ultraviolet photosensitizers to polyolefins. These plastics can be rapidly decomposed after they are used. Therefore, the selection and application of green packaging materials mainly consider the following factors. 1) Use the same packaging material when designing similar packaging products to facilitate recycling. For example, WHIRLPOOL Germany reduced the amount of materials used for packaging from 20 to 4 to reduce the cost of waste disposal to 50%. 2) Full consideration should be given to the recycling of materials, which not only saves raw materials but also facilitates the recycling of resources. 3) Design should consider the degradability of materials. In 1997, the State Environmental Protection Agency announced the environmental labeling and product technical requirements for biodegradable plastic packaging products, and the implementation of the sign recognition system for biodegradable plastic packaging products will greatly improve the pollution status of plastic packaging. 4) Design and produce packaged products that can be re-used for re-use. For example, an ultra-strength bottle developed by a Japanese beer company such as Asahi and Zhaji has doubled its life expectancy compared to the original bottle, and can be used by customers for up to 16 years. Environmental significance is greatly superior to disposable packaging. .

2. Re-understanding of traditional natural packaging materials

Our ancestors began to make direct use of the existing materials around them and packaged their labor and life. The unique quality of the green packaging and the packaging style of the nation were formed. Pure natural value and environmental protection are still not lost its glory.

Plant leaf packaging. These materials include bamboo leaves, lotus leaves, loquat leaves, and the like. For example, in Guangdong's gourd tea, it directly uses the natural bamboo leaves, and a section of the brown tea is tied with fine straw ropes to form small balls that are connected together, resembling the pressurizing gourd that grows in the north. The method of packaging the tea leaves in the original bamboo leaves in the flavor unchanged for a long time, when drinking, at any time can be untied above the straw rope, remove the tea in which the rest of the gourd is still kept under strict storage.

Grass fiber packaging. This is a unique form of packaging in Yunnan, China. People living here have long-term cultivation of rice and poultry. Since eggs are exchanged for items, weaving straws with elastic and strong straw into reticular pouches that can hold eggs, the eggs that are wrapped in straw nets are pink and fresh, giving people a natural and natural freshness. Yunnan eggs are worn with ropes.

Bamboo packing. Our ancestors became indissolubly linked to bamboo and bamboo in the working life of generations. Bamboo rafts have been used as packaging devices for people today.篓 is made of tough and strong bamboo strips, with no trivial detail on the top. It has the pristine beauty typical of natural materials. Various kinds of foods are placed in them. The gap between thin bamboo strips is transparent and natural, and the food is not easily degraded.

Green package design as a new design idea and method. It has attracted wide recognition and attention from all countries in the world. At the same time, it has stimulated the attention of the natural environment at various stages of the cycle of green packaging products, and has formed a green packaging product project with green packaging product design as a leader. Therefore, it is imperative to put green packaging design as a strategy. It will promote the better and faster development of our country's art design and packaging industry toward humanistic survival. Introducing green packaging design into the field of packaging engineering also provides designers with a new thinking point and opens up a new path. As a packaging designer, it is more necessary to devote more energy to the technical system and aesthetic thinking in this field. We are convinced that advocating green packaging design and creating an ecological, humane packaging space with sustainable development will surely become the mainstream of packaging design.
