From circular economy to green packaging (I)

facing the increasing shortage of resources and the continuous tension of coal, electricity and oil transportation, China has to re-examine its socio-economic behavior and development process, and seek a way to achieve sustainable development. Therefore, we should establish a scientific concept of development, The large ASTM (American Society for testing and materials) defines fillers as "In order to improve the strength and various properties, or to reduce the cost, we add inert material resources to plastics to develop a circular economy.

as a packaging designer, on the road of economic development, is he free to carry out packaging design and inadvertently become an environmental destroyer, or blindly cater to abnormal consumption and do not hesitate to become a garbage producer, or create with green ideas and strive to become an environmental protector? This is an unavoidable problem in front of every packaging designer. It is not obscure that what China lacks at present is not only producers and consumers with environmental awareness, but also a large number of green designers. China's ecological environment is suffering from predatory man-made destruction. Therefore, every packaging designer shoulders a bounden responsibility

circular economy is the abbreviation of closed materialscycle economy. It is essentially an ecological economy, requiring the use of ecological laws rather than mechanical laws to guide the economic activities of human society. In contrast, the traditional economy is a linear economy with one-way flow of "resources products pollution emissions", which is characterized by high exploitation, low utilization and high emissions. In this economy, people extract materials and energy from the earth with high intensity, and then discharge a large amount of pollution and waste into the water system, air and soil. The utilization of resources is extensive and one-time, and the quantitative growth of the economy is achieved by continuously turning resources into waste. In contrast, circular economy is loose enough to organize economic activities into a feedback process of "resources products renewable resources", which is characterized by low exploitation, high utilization and low emission

the so-called green packaging refers to commodity packaging that is conducive to protecting human health and the ecological environment. Green packaging is a circular economy in the field of packaging, and it is the application and concrete embodiment of the concept of circular economy in the field of packaging. Green packaging generally has seven connotations: "Hu Diwen, President of Bayer materials technology China, said that the first is to implement packaging reduction. Packaging should minimize the use of packaging materials under the conditions of meeting the functions of protection, convenience and sales. The second is that packaging should be easy to reuse [reuse]. After completing a certain use function, the packaging can be reused after proper treatment. The third is easy to recycle [recycle] 。 Through the production of recycled products, incineration and utilization of heat energy, composting to improve soil and other measures to achieve the purpose of reuse. Fourth, it can be refilled [re "fill]. Cans, bottles and other packages can be canned after recycling. Fifth, packaging waste can be degraded. It will not form permanent garbage in the end, so as to achieve the purpose of improving the soil. 4r1d is a universally recognized principle for developing green packaging. Sixth, packaging materials should be non-toxic and harmless to human body and organisms. Packaging materials should not contain toxic elements, bacteria, heavy metals; Or the content of these should be controlled below the relevant standards. Seventh, the whole process of packaging products from raw material collection, material processing, product manufacturing, product use, waste recycling to final treatment should not cause harm to human body and the environment

as a packaging designer, we should have a strong awareness of environmental protection. In the design process, we should fully consider the function, structure, cycle cycle and final waste disposal of the packaging, accurately and reasonably select materials, and try to be reasonable, material-saving, aesthetic and practical as far as possible. Combined with perfect creativity, green packaging will become a popular packaging. Generally, green packaging design should consider the following aspects and take corresponding measures:

from the perspective of design, first of all, consider green packaging design in terms of function, that is, according to the characteristics of packaged goods, analyze the due functions and the most basic functional characteristics of their packaging products in detail, and further evaluate whether the realization of these functions consumes less materials and energy, causing the minimum load to the environment. Secondly, from the structure. Analyzing the green packaging design from the shape and structure of packaging products is mainly to make the packaging structure more scientific, practical and beautiful. At this level, first of all, we should carefully determine the basic concept of product attributes, and consider how to improve the impact of products on the environment under its framework. In the design process, we should analyze not only the functional structure of products, but also the material structure of products. In terms of functional structure: first, clarify the form, volume, category, attribute and transportation range of the packaged goods, analyze and determine the structural function of the main body of the packaging or the function of the accessories, and further clarify the purpose of the packaging. Secondly, analyze the overall structure and function of the packaging design, and consider whether the relevant functions can be combined or the number of accessories can be reduced, and whether the materials are used most reasonably. Finally, analyze whether it can save materials and reduce volume and weight. In terms of material structure: analyze whether the properties of packaging materials and packaging purposes are configured reasonably; Analyze the material composition, disassembly and actual use of the product as a whole; Try to reduce the types of materials in the same package for classification and recycling. Also, from the perspective of cycle. Consider how to design from the packaging cycle, so as to facilitate the overall description of resource consumption and environmental load in the whole packaging cycle. The specific design methods are as follows: first, establish the operation framework of packaging cycle; 2、 List the total consumption of packaging materials and evaluate the energy consumption in the state of raw materials; 3、 Measure the energy consumption of packaging products during transportation and use; 4、 Determine the recycling rate of recycled materials in packaging products; 5、 Determine the amount of final waste of packaging products. Finally, from the graphics and text. In terms of the expression of design language, more emphasis should be placed on the publicity of environmental protection information, and the elements such as pattern, product name, color and text should meet the aesthetic needs, so as to avoid visual pollution and create a green atmosphere
