Green Packaging Design Strategy (Part 2)

2) Data analysis and assessment of the environmental problems and health damage conditions that may occur in each part of the production process;
3) Use special manufacturing processes for parts that may be subject to pollution problems, and replace the hazardous areas with rationalized product functions and structures. The evaluation of ecological factors mainly refers to: 1) Environmental property indicators, ie indicators related to the environment within the safety cycle of packaged products, including air pollution indicators, liquid pollution indicators, solid pollution indicators and noise pollution indicators.
2) The resource attribute index, namely the material resource index, design resource index, information resource index and human resource index used in the product cycle cycle.
3) The energy property index refers to the indicators such as the utilization rate of green packaging products and the energy consumption for recycling.
Third, the choice of materials in the green packaging design In the early stages of industrialization, seldom consider the impact of materials on the environment, but the choice of materials in the green packaging design is critical, it not only determines the degree of product damage to the environment, but also Determines the recyclability of products. It is a complex task to select the appropriate materials to meet the requirements of sustainable production when designing packaging products. It is also a comprehensive consideration of material properties, environmental factors and knowledge in the field. The process, therefore, designers in-depth, detailed and specific understanding and control of environmentally friendly packaging materials and applied to green packaging design practices, to minimize the pollution of the material, to maintain the ecological balance of the natural environment, the social environment, but also to promote The use of earth resources by the packaging industry is transformed from a consumptive type to a recycling type.
1. The characteristics of the material and the characteristics of the applied material often determine the effectiveness of the material energy in the production process and its 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 use existing materials directly around the world and packaged their labor and life to form a unique green packaging quality connotation and The national packaging style, which contains pure natural value and environmental protection, still retains 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.
