Since the human society has commodity circulation, there has been the existence of packaging. The initial packaging is very simple, such as pottery pots, straw baskets, straw ropes, leaves, wooden boxes, etc. At that time, the role of packaging was limited to protecting goods and easy transportation. With the development of commodity economy, packaging has become a means of marketing, which plays a role in protecting goods, facilitating transportation, identifying, conveying information, reflecting culture and promoting sales. Now, packaging has become an important process that can not be ignored in the production of products. Just as people enjoy the convenience, health, safety and aesthetic taste brought by packaging, a crisis is quietly attacking people. This is the waste of resources and environmental pollution caused by a large number of packaging waste in recent years. According to statistics, the global consumption of plastic packaging alone is more than 30 million tons, and plastic packaging waste accounts for one third of the total. China is the fourth largest plastic producer in the world, with an annual output of 15 million tons, of which 30% is used for packaging. 70% of these plastic packages are disposable and discarded. Some people pointed out that in the future, China's packaging waste will increase by 3% - 5% every year, which will destroy the ecological balance and become a public hazard. The revolution of science and technology in the world has brought about the rapid development of social productivity, produced huge material wealth for human beings, and also brought a series of environmental problems. Many global environmental problems, such as environmental pollution, resource depletion and ecological destruction, restrict the sustainable development of economy and endanger the long-term interests of mankind. In 2005, environmental protection has been strengthened in China's 2005 plan, which requires reasonable population control, sustainable and rational utilization of resources, improvement of urban and rural environment, inhibition of ecological deterioration, and improvement of quality and efficiency of economic development. As an industrial sector, packaging industry is also faced with environmental and resource problems without exception. Packaging can make the goods reach consumers safely, the credit of packaging is obvious. The problem is not in the packaging, the key is to correctly handle the relationship between packaging and the environment. The following will talk about the environmental protection design of packaging products from several aspects. First of all, the environmental protection design of commodity packaging should start with the packaging materials. Environmental protection materials refer to the materials with good environmental compatibility on the premise of meeting the general functional requirements. It has been generally agreed in the academic and industrial circles that environmental protection materials and their technologies are the inevitable trend of materials development. Pay attention to the following points when selecting materials. 1) Materials with low energy consumption and low pollution should be selected as far as possible. Paper materials are widely used in packaging industry. The raw materials of paper are mainly natural plant fibers, which will be decomposed quickly in nature, resulting in low environmental pollution and can be recycled. Renewable materials, such as recycled paper, recycled pulp, recycled plastics and recycled glass, are preferred The glass bottles used in beer, beverage, soy sauce, vinegar and other packaging are reusable materials; 2) Materials with good environmental compatibility shall be selected and toxic, harmful and radioactive materials shall be avoided. The materials used shall be easy to be recycled, reused, remanufactured or easily degraded. For example, the glutinous rice paper used in the familiar candy packaging, and the corn baking packaging cup for ice cream are all typical edible packaging. These materials are not only economical but also pollution-free, which is worthy of promotion. The selection of environmental protection materials is the premise and key factor in the development of environmental protection products. When selecting materials, we should not only consider the functions of packaging products, but also consider the environmental constraints. We should select those non-toxic, non polluting, recyclable and degradable materials, such as reusable and renewable packaging materials, edible packaging materials, degradable materials, paper materials, etc. Generally speaking, cardboard, metal, glass, degradable plastics, bamboo, cloth and so on are all environmental protection materials; 3) The environmental protection design of commodity packaging should consider the structural design of the commodity, and the packaging structure should be simplified as much as possible. The excessive packaging of goods not only consumes more materials, increases the packaging volume, causes waste of resources, but also increases the amount of urban garbage, which is not conducive to environmental protection This situation should be avoided as far as possible in packing. For example, in the past, the moon cake packaging, single small packaging, combined medium packaging, plus the outer packaging of large boxes, three layers inside and three layers outside, only 6-8 mooncakes were packed. The value of the packaging was several times higher than the value of the commodity. The pollution and waste caused by such packaging were particularly serious. Nowadays, the promotion of simple moon cake packaging has increasingly adapted to the needs of the market.At the same time, by changing the structure of goods, we can reduce the weight of goods, improve and reduce the cost, and reduce the adverse impact on the environment. Of course, it can also improve the internal structural strength of commodity packaging, reduce the risk of damage in the process of transportation, reduce the repeated application of packaging materials, and reduce the cost of packaging. Second, the environmental protection design of commodity packaging technology, the realization of environmental protection technology mainly includes the following aspects. We should change the input mode of raw materials, use them on the spot, reuse valuable by-products and recycled products, recycle various materials in the process; change the production process or manufacturing technology, improve the process control, and transform the original equipment, so as to minimize the consumption of raw materials, waste production, energy consumption, health and safety risks and ecological damage According to the relative scale of environmental load, the impacts on biodiversity, human health and natural resources are determined. Third, the environmental protection design of recycling treatment, which is a design idea and method to consider a series of problems such as the possibility of packaging material recycling, the size of recycling value, and the recycling treatment methods in the early stage of packaging design, so as to achieve the maximum utilization of packaging materials and energy, and minimize environmental pollution. The contents of recyclability design include: recyclable materials and signs, recyclable technology and methods, economic evaluation of recyclability, recyclable structure design, etc. At present, many countries in the world are using direct recovery technology to collect, classify, crush, clean, melt or directly shape plastic bottles. In order to improve the classification efficiency, an automatic sorting system for plastic bottles was developed in the United States. By using a computer-controlled mechanical device and a fluorescence sensor, PVC bottles were automatically detected from the mixed bottles of PVC and pet and picked out on the conveyor belt. Chinese environmentalists point out that the main culprit of "white pollution" is not the lunch box and plastic bag itself, but the poor recycling. At present, some cities in our country also put forward that the one-time lunch box who produces is responsible for recycling, and has formulated the reward and punishment policy for recycling, which has played a better effect. In some cities, the waste plastic packaging is reprocessed into recycled plastics by conversion and recycling technology, which is well received by the industry. At present, China's government has invested a lot of money to plan and build waste recycling, refining and power generation projects, which is of great significance for the protection of the ecological environment and sustainable development. Fourth, the cost analysis of packaging and environmental protection design in the use process The cost analysis of environmental protection packaging is different from the traditional packaging cost analysis. It is the analysis of product recovery, recycling and other performance must be considered in the early stage of product design. In addition, for enterprises, whether to spend environmental protection costs will also affect the cost accounting of products, and the actual costs of the same environmental projects in different countries are also different. Therefore, the environmental protection packaging cost analysis should be carried out at the beginning of each design, so as to make the design and packaging cost lower. The use of goods will consume resources and bring burden to the environment. Therefore, in the stage of commodity packaging design, attention should be paid to the energy consumption and environmental pollution caused by the use of goods. The design of environmental protection products should be oriented to the use process of commodities, combined with the use characteristics and working mode of commodities, adopt advanced technology and technology, improve the design scheme, and reduce as much as possible Energy consumption of goods in use. There is a product, there is packaging. Now more and more countries and regions advocate the green revolution of packaging industry, that is, green design, for the sake of environmental protection design of commodity packaging. Green design refers to incorporating environmental factors and pollution prevention measures into product design at the design stage, taking environmental performance as the design objective and starting point, and striving to minimize the impact of products on the environment. Green packaging design promotes green design from the aspects of packaging reduction, easy abandonment, utilization of recycled materials, refilling, returnable for permanent use, recycling of renewable materials, energy saving countermeasures of other provinces, utilization of natural protection materials, etc. at the same time, green packaging is divided into different types and levels in the form of laws and regulations. At present, many countries and regions have taken effective measures to carry out the green revolution in the packaging industry. Governments and non-governmental organizations of various countries have taken joint actions to jointly prevent environmental pollution in the packaging industry and the whole environmental field. More and more consumers like to buy products with "environmental protection marks". The international community has also formulated different laws and policies as well as environmental protection packaging standards It can be predicted that environmental protection design of packaging will be an important trend in the development of packaging industry. With the decrease of various resources on the earth and the deterioration of living environment, it is imperative to develop environmental protection packaging. Whoever develops fast will occupy an important position in the packaging market. It can be predicted that the environmental protection design of commodity packaging will be the theme of the global packaging industry in the new century, and it is also the significant feature of the development of the packaging industry in the new century.
