Abstract Green logistics is an important part of sustainable development. Green logistics includes the content of green packaging. Green packaging is an important part of green logistics. Green packaging strategies based on green logistics include: strengthening green packaging awareness, making full use of recyclable containers, grouping industrial logistics, and strengthening design research of green packaging. Keywords green logistics, green packaging, sustainable development I. Proposal of the problem Green logistics and green packaging are two words that have received enough attention in the logistics industry. However, it is rare to connect these two words and study their relevance. Green logistics has a close relationship with green packaging. Its research not only promotes the sustainable development of logistics, but also contributes to the improvement of logistics efficiency and the expansion of benefits. Second, sustainable development strategy The sustainable development strategy means that the socio-economic development must be linked with the natural environment and the social environment, and the economic construction should be coordinated with the resources and the environment so as to ensure that the society can achieve a virtuous circle of development. With the increasing degree of social civilization, the economic development must be based on the maintenance of the global environment. The development and utilization of resources in the modern era must be conducive to the maintenance of the next generation of environment and the sustainable use of resources. The basic content of sustainable development includes the following five points: (1) development is the key; (2) economic and environmental protection are developed to make it an organic whole; (3) a reasonable and effective economic and political operating mechanism should be established; (4) ) People's own development needs are compatible with the development of resources and the environment. People should abandon traditional production methods and lifestyles; (5) Establish a new and modern cultural concept. In order to control the social waste caused by social and economic development, ecological imbalances, environmental pollution and other social problems, from the 1970s onwards, Western countries proposed the topic of sustainable development, and has gradually entered the substantive implementation stage in environmental protection. China's economic and social development is also facing social problems such as environmental pollution: (1) China's urban atmospheric environment, pollution is quite serious, according to surveys in 73 cities, cities that exceed the limit have accounted for about 70%; (2) China's current water The shortage of resources and water pollution are becoming more and more serious. There are more than 300 cities in the country that are short of water. The annual output value of industrial output is over RMB 120 billion due to insufficient water supply. Among the seven major water systems in the country, Songhua River, Liaohe River, Huaihe River, Haihe River, and Yellow River are 40-70%. The water body has been reduced to the worst four-category and five-category standards; (3) The noise of urban roads in China has remained high for 14 years, and 47% of the urban areas in China have been polluted by noise; (4) The pollution of garbage has become the end of the century. Serious topics. According to statistics from relevant departments, the annual production of domestic waste in cities in China is more than 100 million tons, and the country’s annual waste storage volume has reached more than 6 billion tons and covers an area of ​​more than 660,000 acres. The problem of ecological environment has been very serious and has drawn attention and attention from the government and the whole society. As the main producer of environmental pollution, enterprises must take social responsibility in environmental protection. The implementation of the strategy of sustainable development requires that logistics enterprises undertake social responsibilities in their production and operation activities, coordinate logistics activities with the development of the natural environment and social environment, and make their own logistics activities conducive to a virtuous cycle of environmental development. $Page break $ Third, green logistics and green packaging (a) Green Logistics One of the principles of sustainable development is to make today's commodity production, circulation and consumption not affect the environment and resource conditions of future production, circulation and consumption of commodities. Applying this principle to modern logistics management activities requires that the modern logistics system be studied from the perspective of environmental protection to form an integrated logistics system that is symbiotic with the environment, changing the one-way relationship between the original economic development and logistics. , inhibiting logistics from harming the environment, and at the same time forming a modern logistics system that can promote the healthy development of economy and consumer life. This logistics system is green logistics. Green logistics is an important part of sustainable development. Together with green manufacturing and green consumption, it constitutes a green economy cycle system that conserves resources and protects the environment. Green manufacturing (also known as clean manufacturing) is a research hotspot in the manufacturing field. It refers to the production of green products in a way that saves resources and reduces pollution. It is a kind of production behavior; green consumption is a consumer-oriented consumer behavior. Green logistics and green manufacturing and green consumption are infiltrating and interacting with each other. Green manufacturing is the premise of realizing green logistics and green consumption. Green logistics can promote green manufacturing through the counteraction of circulation to production, and meet and promote green consumption through green logistics management. The purpose of green logistics is to restrain the logistics from harming the environment in the process of logistics, and to achieve the purification of the logistics environment so that the logistics resources can be utilized to the fullest extent. Green logistics is actually a branch of logistics management and environmental science. When studying social logistics and corporate logistics, we must consider environmental issues. In particular, during the acquisition of raw materials and the distribution of products, transportation as a major logistics activity may have a series of impacts on the environment. Moreover, how to properly recycle used materials, reduce the pollution to the environment and the greatest possible reuse is also something that logistics management needs to consider. Green logistics is a multi-level concept that includes both the company's green logistics activities and the society's management, specification and control of green logistics activities. From the perspective of the scope of green logistics activities, it includes all single green logistics operations (such as green transportation, green packaging, green circulation processing, etc.), as well as waste recycling logistics for recycling of resources. (b) Green packaging Green packaging is the packaging that meets the requirements of environmental protection. It requires that the packaging of goods is harmless to ecological balance and harmless to human health. Specifically, green packaging generally refers to the use of packaging materials to save resources and minimize packaging waste. It facilitates recycling, reuse, and recycling after use to become other useful materials; it occupies less land and is easy to degrade. In international trade, any environmental protection measure may be a trade barrier while benefiting environmental protection. Therefore, trade disputes caused by the environmental protection requirements of packaging have accelerated the development of green packaging in countries around the world. For example, Austria began implementing new packaging regulations in October 1993; the British government requires packaging material manufacturers to develop plans for the reuse of packaging waste. Other countries and regions, especially developed countries and regions, also have positive responses to green packaging. With the advancement of science and technology and the improvement of people’s awareness of environmental protection, the connotation of green packaging is increasing, so green packaging is a dynamic concept. In general, it should be a package that is conducive to environmental protection and the use of renewable resources, including the following components: It can be reused, reused, or degraded, and it will not cause harm to the human body and the environment throughout its life cycle. Many developed countries have summarized green packaging as packaging based on the "4RID" principle, namely Reduce, Reuse, Recycle, Refill, and dwgradble. Degradable packaging). The promotion of green packaging is inseparable from the development of packaging technology. Packaging technology is also a system technology. It involves many aspects such as packaging design, raw materials and accessories, and machinery, and requires close cooperation among various departments. (3) Relationship between green logistics and green packaging Green logistics includes green packaging. Green packaging is an important part of green logistics. Green packaging not only serves green logistics, but also has other cultural significance. For example, product packaging should not only meet the requirements of high efficiency, convenience, and not easily damaged in the process of logistics transportation, but also must be aesthetically pleasing, practical, and material-saving. The relationship between them is shown in Figure 3.3. Fourth, green packaging strategy based on green logistics (A) Strengthen the awareness of green packaging At present, many companies still focus their attention on the protection of the value of the use of goods when packaging products, while seldom consider environmental protection issues. In today's "green wave" sweeping the world, companies should establish a green marketing concept, and further recognize the status and role of green packaging in the field of international circulation. It should be clearly understood that the development of green packaging not only can reduce energy consumption and material consumption, reduce costs and reduce pollution, but also can enhance corporate image, increase consumers' sense of corporate identity and trust, and thus improve the product's international competitiveness. (B) make full use of recyclable containers China has a large population and the total amount of packaging waste is high, causing serious pollution to the ecological environment. In addition, China is still a large developing country. Its economic strength is not strong and per capita resources are insufficient. However, waste utilization rate is very low, and the paper recycling rate is only 15%. At the same time, China has imported hundreds of thousands of tons of pulp each year with a large amount of foreign exchange, resulting in the waste of resources and the outflow of foreign exchange. To solve this problem, recyclable containers should be widely used in logistics packaging. Recyclable containers have always been part of the logistics system. Most reusable packaging products are steel or plastic packaging. However, there is a tendency for many small items and parts, such as spices, to also be transported between factories using recyclable protection materials and between warehouses and retail stores. The use of recyclable packaging is becoming more and more common. They all have one thing in common: they all have a complete marking system to control the circulation of containers. In recyclable packaging systems, the parties must explicitly use this marking to maximize the use of the container. Otherwise, the container will be lost, misplaced or forgotten. (III) Industrial Logistics Grouping In industrial packaging, individual goods and parts boxes, bags, boxes, and barrels are usually grouped to improve the efficiency of operation and management. These containers are used to group fragmented commodities into MCSs. When MCSs are grouped into larger units, they are called containerization or grouping. The basic method of grouping consists of a rigid method of forming a unit load of a container and a method of grouping a carrier tool. Containerization encompasses all forms of grouping from grouping two MCSs together to grouping using specialized transport equipment. All types of containerization have a basic purpose, which is to improve the efficiency of material handling. And can save packaging energy, prevent product leakage and pollute the environment, so as to achieve the purpose of green packaging. (D) Strengthen the design research of green packaging From the point of view of China's export packaging, there are problems with poor material quality, poor gasketing, unreasonable transport strapping, unclean appearance, and lack of hygiene standards. In the face of green packaging requirements in the international market, we must vigorously promote the development of packaging technology. The cost of paper in China is higher than that of plastics, which makes the environmental protection requirements of the packaging contradict with the interests of the enterprise. There is a contradiction between environmental protection and economic growth. To resolve this contradiction, we must increase technological content, improve technology, and reduce costs. At present, China's plastics, rubber and other industries have developed rapidly. Fresh raw materials have been declining. Recycling companies are lagging behind in recycling technology, and high collection and transportation costs have caused higher costs. The difference between the two is getting smaller and smaller. . Therefore, we must constantly devote ourselves to the research, development and utilization of new technologies and new processes, accelerate the improvement of recycling technologies, reduce the cost of recycled raw materials, and develop green packaging materials in order to occupy the market more powerfully in the further future. V. Conclusion The research on logistics that benefits the country and the people, green logistics and green packaging is more conducive to the realization of sustainable development strategies. At present, the research on how to achieve green packaging in logistics systems is not yet in-depth. Most of the articles only propose some macro-level countermeasures, and their quantitative research needs to be further studied. This is also the weak link in this logistics research. This article puts green logistics and green packaging together, and proposes a green packaging strategy based on green logistics, which may not be mature enough, but it aims to start a business in order to arouse the interest of the logistics industry in its research.
