The development of society has driven the change of demand, promoted the continuous renewal of logistics and packaging concepts in the process of integration, and gradually formed a rational development trend. Developing modern logistics is the need of comprehensive, healthy, rapid and sustainable development of national economy. Circular economy is the main direction of the current world economic development, which has been identified by China as the future economic development model. The life cycle of packaging products is short, most of them are disposable, and the resource consumption is very serious; Its solid waste has caused serious pollution to the environment, so it is more urgent for the packaging industry to implement circular economy. In the modern material society, the rational use of packaging promotes the perfection of logistics system and builds a harmonious and economical commodity circulation society. According to the concept of circular economy, the development of modern logistics puts forward higher and newer requirements for packaging with reduction as the core-providing green packaging and building a green logistics system. Using the concept of circular economy to develop green packaging. The development of packaging industry should conform to the principle of circular economy. Circular economy is a form of social production and reproduction that uses ecological laws to guide human social and economic activities, takes efficient utilization and recycling of resources as the core, takes "reduction, reuse and recycling" as the basic principle, and takes low consumption, low emission and high efficiency as the basic characteristics. Its essence is to consume as few resources as possible. The most important operating principle of circular economy is the "3R" principle, that is, reduction, reduction and recycling. The importance of the three principles is different, and the order of the three principles cannot be changed. Reduction is one of the most important principles. Reduction is to reduce the quality of materials entering the consumption process, and the key point is to prevent waste generation rather than post-production treatment. At present, excessive packaging wastes resources and produces a lot of waste, and disposable packaging does not conform to the principle of reduction. Secondly, we should pay attention to the reuse of packaging materials. Packaging materials such as cartons, glass bottles and plastic bags can be reused to save energy and materials. Third, we should recycle or reuse as much as possible. The so-called recycling refers to returning substances that have completed their use value to the factory, and then integrating them into new products after treatment. Recycling can reduce people's pressure on landfills and incinerators, and make new products that use less energy. Generally speaking, primary recycling can reduce the consumption of raw materials by 20}90% when forming products, while secondary recycling usually only reduces the consumption of biomass raw materials by about 25%. 2. Take the development of green packaging as the industry direction. Green packaging is not only a packaging concept, but also an ideal packaging. So far, there is no unified definition and evaluation standard. However, the green trade barriers in international trade put forward more and more strict requirements for packaging. Green barriers in many industrialized countries, such as technical standards, environmental standards, packaging labels and environmental labels, health inspection and quarantine regulations, mainly restrict packaging: toxic and harmful elements contained in packaging materials, microbial germs that affect ecology or human health, and organic solvents or heavy metal residues that may migrate like containers in packaging and printing; Packaging waste recycling or self-degradation performance; There are four aspects: whether there are environmental protection signs. At present, the connotation of green packaging includes the following five points: reducing packaging; Packaging should be easy to reuse or recycle; Packaging waste can be degraded and corrupted; Packaging materials should be nontoxic and harmless; Packaging products should not pollute the environment in the whole life cycle. The first four points should be the requirements that green packaging must have at present, and the last point is the highest requirement for green packaging from the point of view of system engineering based on life cycle analysis method. 3. Develop green packaging to meet the challenge of environmental trade barriers to China packaging logistics industry. In international trade, as a new form of trade protectionism, environmental trade barriers have emerged, and their influence is growing, affecting almost all areas of China's foreign trade exports. Green packaging is becoming a new non-tariff barrier-green barrier. For example, 1998, the European Union unilaterally prohibited China's wooden packing boxes and wooden pallets from entering the country without quarantine, resulting in billions of dollars in economic and trade losses for China. Later, in 2000, it was announced that wooden packing boxes and wooden pallets imported from China, Canada, Southeast Asia and the United States must be fumigated and disinfected. Too strict green packaging standards in developed countries have raised the "threshold" of trade. In 2000, the European Union took greater action against environmental trade barriers, requiring the recovery rate of household appliances, electronic products and communication supplies to be above 60%, and the recovery rate of individual products to be as high as 75%. Among them, the recovery rate of packaged products reaches 85%, and this regulation will be formally implemented on June 5438+ 10. In recent years, there are more and more trade frictions caused by packaging problems, and many goods exported to Europe and America have to pay high packaging waste disposal fees. China's packaging industry, production enterprises and logistics enterprises are all facing severe challenges. Second, measures to develop green packaging and build a green logistics system. Developing green packaging is a systematic project, including packaging containers, packaging materials, packaging technology, production technology and waste disposal technology, which is a new development of packaging discipline. To study green packaging, we should innovate constantly, develop new energy-saving and environment-friendly materials, improve the test level of evaluating the performance of packaging materials, and establish corresponding standardized working procedures. At the same time, packaging machinery must be upgraded to improve the technical level, and packaging design and printing assembly should contain more abundant information and characteristics of the times. In addition, the corresponding laws and regulations, the technical definition of green packaging and the education and training of talents will involve all aspects. 1. Strengthen legislation and law enforcement to ensure the healthy development of green packaging. Relevant domestic departments should formulate corresponding policies and regulations to guide, support and protect green packaging enterprises and products, and at the same time order enterprises that do not meet the development direction of green packaging to rectify or shut down. When formulating laws and regulations, relevant domestic departments should not only learn from the advanced experience of developed countries to improve their technical level, but also carefully study the packaging environment in combination with the actual situation in China, so as to make legislation comprehensive and rigorous, in line with international standards, and strive to strictly regulate law enforcement to ensure the healthy development of green packaging. 2. Intensify technological innovation, focus on reduction, and actively develop and popularize all kinds of green packaging materials and equipment to meet the needs of the development of logistics industry and international trade. ▲ corrugated boxes should be miniaturized and reduced. Corrugated box packaging is widely used and plays an extremely important role in transportation packaging and logistics system, ranking first among all kinds of packaging. In 2004, the total industrial output value of China's paper product packaging industry was 654.38+008.57 billion yuan, accounting for 33% of the total industrial output value, accounting for 43.69% of the total industrial output value of plastic packaging, metal packaging, glass packaging and paper product packaging, and the production capacity has been occupied. Only its automatic production line has grown from more than 600 lines of 1995 to more than 4,000 lines in 2004. China's output of corrugated boxes has surpassed that of Japan, second only to that of the United States, and it has entered the world's largest carton packaging country from backwardness, but it is not yet a strong country. At present, there are many phenomena in corrugated box packaging industry, such as waste of resources, overcapacity and insufficient start-up (the average start-up rate is only 35%-40} I 'o); Market supply exceeds demand, disorderly competition, low enterprise efficiency and enlarged losses; Generally speaking, it is still in the primary industrialization stage. Take a single production line as an example: the annual output of a line in the United States is 60 million square meters, that of Germany is 57 million square meters, that of France is 44 million square meters, and that of China is only 4 million square meters, which is quite different. Therefore, it is a development trend to speed up and upgrade the production of corrugated board. Reducing backward equipment and closing small enterprises are important tasks for the development of paper packaging industry. In the future, the development of corrugated box industry should focus on reduction and develop towards miniaturization and low grammage. Three-watt cartons in developed countries have become the mainstream of the market, which can greatly save paper consumption, wood and energy, while in China, on the contrary, five-watt cartons are the main ones (see chart). In 2003, the output of corrugated boxes was 65.438+058 billion square meters, and more than 70% of consumables in China were used. In recent years, following new packaging materials such as honeycomb cardboard, heavy corrugated cardboard, 3A "special corrugated cardboard and reinforced corrugated cardboard (commonly known as" tile in tile "), micro corrugated cardboard (also known as" micro corrugated cardboard ") has been more and more favored by people, and will be the direction for China's packaging industry and logistics industry to achieve sustainable development. At present, there are still some problems in the production of miniature corrugated board in China, such as late start, few varieties, low grade, low production technology and process level. More high-grade miniature corrugated board still needs to be imported. Therefore, domestic micro-corrugated cardboard manufacturers need to develop micro-corrugated cardboard boxes (boxes) with higher compressive strength, better cushioning performance, more exquisite printing, overcoming the "washboard" phenomenon and lower cost as soon as possible. ▲ Accelerate wood saving and substitution in transportation, packaging and logistics systems. "Modernization of packaging, mechanization of loading and unloading, containerization of transportation, shelving of storage and informatization of management" are the basic principles and contents of implementing the reform of transportation packaging and developing the logistics industry. For a long time, wooden pallets and wooden products packaging are the main products of transportation packaging, which play an extremely important role in the logistics system, but they consume a lot of wood. China is a country with a relative shortage of wood resources in the world. With the increasing consumption of wood, the contradiction between supply and demand has become increasingly prominent. Therefore, saving wood and substitution are important ways to alleviate the contradiction between wood supply and demand and realize the sustainable utilization of wood resources. In accelerating the key links and work of wood conservation and substitution, document No.58 of the State Council [2005] pointed out that it is necessary to develop wood substitution and optimize the wood consumption structure. Advocate and encourage the production and use of wood substitutes, give priority to the use of economic, durable, recyclable and environmentally friendly green wood substitutes and their products, and reduce the unreasonable consumption of wood. Continue to promote plastic, metal, bamboo and other non-wood packaging and wood-plastic composite packaging in packaging and transportation; Restrict the production and use of disposable wood products and wood packaging materials mainly based on natural trees, and restrict the transitional wood packaging behavior of consumer goods such as food, beverages and alcohol. Therefore, in the logistics system, we should vigorously promote the latest international transportation packaging technology-winding packaging instead of wooden box packaging and corrugated box packaging, in order to save wood resources and realize the reduction of transportation packaging. This is an effective way for enterprises to reduce packaging costs and improve economic benefits, and it is also an important measure to deal with international environmental trade barriers. Winding packaging technology is a new modern technology in the field of transportation and packaging in recent years, and it is the basis of promoting container transportation and logistics industrialization. It uses a winding stretching film made of a specific formula and process, and a winding packaging machine made of advanced electronic technology and exquisite mechanical manufacturing technology to wrap all kinds of products with regular or irregular shapes into a whole, so as to prevent goods from being scratched, bumped, damaged, lost and scratched, reduce the generation of oil stains and dirty spots, and reduce economic losses caused by poor packaging. The application of winding packaging technology can not only change the original backward packaging of products, but also improve the unit loading capacity and improve the efficiency of loading, unloading and transportation. Ensuring the safety of loading and unloading personnel and means of transport is the basis for developing container transportation and logistics industry. Winding packaging technology can also greatly reduce the cost of goods (products) packaging and improve the economic benefits of enterprises, which is also the key to the rapid development of winding packaging technology. The emergence of winding packaging technology has replaced all kinds of paper packaging and wood packaging, which can greatly reduce the consumption of wood, paper and other resources. I have also found a good F-reduction countermeasure for reforming transportation packaging and developing logistics industry. Compared with other methods of composing unit goods (such as bundling, bonding or using shrink film), stretch film packaging has a wide range of adaptability, which can package products of various configurations, realize product stacking of the same size and meet the requirements of various goods. 3. Actively develop new advertisements. Star valve port packaging bag replaces the original plastic-plastic composite bag, paper-plastic composite bag, prestressed composite bag and glass fiber reinforced bag. Advertising. STAR's new packaging bag is the latest product in the world, with light weight, high strength, high wear resistance, high waterproof, low price, convenient operation and environmental protection (it can be recycled into other products, and a certain amount of energy can be obtained by proper incineration, and the burned fertilizer has no pollution to water and land). It has a wide range of uses, which can protect packaged goods from being broken during transportation and storage, and reduce the economic losses caused by poorly packaged products. Advertising. Star's new packaging bag is the best product for packing bulk materials such as cement, grain, fertilizer, carbon black, plastic particles, sugar, salt, feed and sand according to the actual situation in China. It can replace those plastic-plastic composite bags, paper-plastic composite bags, prestressed composite bags, etc., which are widely used but are eliminated at high prices or low prices. China is the country with the largest demand for packaging bags in the world, with an annual demand of 654.38 billion packaging bags. With an annual output of 36 million bags, China needs to build more than 300 factories of the same size. Currently, AD. Stars, new packaging bags and advertisements. Star new packaging bag production line is still blank in China, and the market prospect is broad. Secretary hodgepodge network
