New trends and Countermeasures of the packaging industry under the guidance of the scientificoutlookondevelopment (Part 2)

2 2. Industrialization of recycling and utilization of packaging waste resources

waste packaging of paper, plastic, glass and metal can be recycled with certain technologies to make it recyclable and recycle resources. Moreover, compared with the production of new packaging materials with natural raw materials, it can save more energy, which is of great significance in the current era of energy tension. For example, recycling new packaging materials from recycled aluminum cans can save 95% of energy compared with aluminum packaging materials made from bauxite, recycling steel and glass waste packaging to make new packaging materials can save 50% - 75% of energy compared with producing new packaging materials from ore or quartz sand, and adding each ton of broken glass to the furnace for remelting can also save 25kg of soda ash compared with melting new glass with quartz sand; Compared with making new packaging from resin, packaging containers made of recycled waste plastic can save 85% - 96% energy and 85% resin consumption; Compared with the production of paper from raw materials, the production of recycled paper from waste paper can also greatly save energy and reduce environmental pollution

therefore, countries all over the world attach great importance to the recycling of waste packaging resources. In the UK, 2/3 of the waste paper is recycled, and recycled paper is produced by removing impurities, deinking, bleaching and a certain amount of new pure wood pulp. At present, recycled paper in the UK accounts for 55% of the total production of paper and paperboard, and 80% of packaging paper products, becoming a pivotal industry; The United States attaches great importance to the establishment of waste paper recycling networks, so that the recycling rate of waste paper can reach 70%, and the recycling rate of corrugated cardboard can reach 75%. After the production of recycled paper and paperboard, a large number of exports can be made to earn foreign exchange. It is the fastest-growing industry in the 1990s. The output value of American waste treatment international company has reached 6billion US dollars at the end of the 20th century. Japan has avoided the formation of garbage islands for 30 college students from Zhejiang University of technology, The recovery rate of waste paper reaches 80%, and the production of recycled paper has become the second largest industrial park of recycled paper outside the UK; Germany passed legislation to enforce the recycling of waste packaging resources, and established the famous green dot company (DSD), with network systems all over the country. At present, the recycling rate of paper, metal and glass waste packaging has reached 65% - 80%, and the recycling rate of the most difficult waste plastic packaging has also reached 50%; Western developed countries also attach great importance to the recycling of waste metal, and its recycling volume has reached more than 20% of its metal consumption. In 1994, Japan correspondingly adjusted or cleaned the recycling rate of waste metal cans has reached 69.8%

under the guidance of the scientific concept of development and the promotion of the development of circular economy, the recycling of packaging waste resources in China is bound to become a new industry, which is another new trend of the development of packaging industry in China. In order to form the industrialization of recycling and utilization of packaging waste resources, we should seriously solve three problems:

1) the state should legislate, and the "packaging waste restriction law" based on the principle of polluter pays should be introduced as soon as possible; 2) To establish a recycling network system, Germany's DSD operation system and mechanism can be used as a reference for China; 3) We should vigorously develop recycling, recycling, especially recycling technology

2. Green packaging materials will be vigorously developed and developed

driven by the scientific concept of development and the tide of paying attention to environmental protection, green packaging has become an inevitable trend in the development of packaging in the world. In the future, in addition to the functions of protection, convenience, promotion and information, packaging must be added with environmental protection functions. Packaging without environmental protection functions will be phased out under the resistance of green barriers around the world. Green packaging materials are the most critical factor in the development of green packaging. Therefore, the momentum of research, development and production of green packaging materials in the future will also be further promoted and developed. Green packaging material is an important branch of material science. Due to the great demand for packaging, its development and research will attract the attention of other material researchers except the packaging industry

green packaging materials have two meanings: saving resources and protecting the environment. It refers to the materials with the lowest environmental burden and the highest recycling rate in the whole life cycle. In addition to the generality of general packaging materials, it also needs to have good operation convenience, environmental performance, resource performance, reduction performance and recycling performance. According to the current progress of research and development in various countries, green packaging materials can be summarized into the following aspects:

1) recyclable or recycled packaging materials; 2) Degradable plastic packaging materials; 3) Edible packaging materials; 4) Natural plant fiber packaging materials; 5) Transgenic plant packaging materials; 6) Lightweight, thin, fluorinated free, high-performance packaging materials; 7) Substitute wood packaging materials; 8) Green nano packaging materials; 9) Green packaging auxiliary materials (adhesives, inks, coatings); 10) Green packaging material additives

in the future, the research and development of green packaging materials in China should focus on the resource situation in China, take resource conservation, degradability and easy recycling as the main direction, closely track international trends in high-tech, adopt international green standards in research and development and production, strengthen the research and development cooperation between scientific research institutes and production enterprises, and strive to make the research and development of green packaging materials in China rank in the forefront of the world

2. 4. The development of basic packaging industry will be accelerated

China's packaging industry consists of two parts. The first is the basic packaging industry based on packaging raw and auxiliary materials and packaging machinery and equipment; The second is the packaging products industry, which is composed of paper, plastic, metal and glass packaging and packaging printing. At present, through more than 20 years of efforts, the second piece of packaging products has completed a leap in quantity, making China a big packaging country in the world; However, the first basic industry is weak, which does not match the second, resulting in the unreasonable industrial structure of China's packaging industry. At present, high-grade packaging raw materials such as PVC, pet, PE, PP, PS and other resin raw materials, high-grade wood pulp paper and paperboard, corrugated core paper, aluminum foil and so on all need to be imported; The overall level of packaging machinery is 20 years behind that of developed countries, and the current domestic demand is 60% - 70%, especially complete sets of equipment with high technical content, such as complete sets of corrugated board production equipment, plastic packaging production line, light glass production line and complete sets of packaging and printing equipment, also need to rely on imports; At present, the overall production situation of packaging machinery in China is that there are many products with simple structure and low technical content, and there are few products with high-tech added value and high production rate; There are many general machines and few packaging machines for processing special requirements and special materials; There are many single machines, few complete assembly lines, and the complete matching is especially poor; Heavy production and processing, light research and development, independent research and development of innovative products are few. Therefore, China's basic packaging industry has little support for the product industry, which is also an important reason why China is not a "packaging power" although it is a "packaging power" at present. According to the scientificoutlookondevelopment, "comprehensive and coordinated" development is required. In order to establish an independent and complete packaging industry system in China, the internal industrial structure of China's packaging industry must be adjusted and balanced, and the basic packaging industry is bound to be strengthened and developed

with the economic development of China and the growth of foreign trade exports, it is expected that by 2010, the demand for the size of the packaging market will reach at least 500 ~ 600 billion yuan. In the 21st century, China will be the largest packaging market in the international economy, and the corresponding demand for packaging raw materials and packaging machinery will also increase significantly. According to experts' prediction, the annual growth rate of global packaging machinery demand is 5 About 3%, it will reach US $29billion in 2005 and increase to US $40billion in 2010, of which China and India will account for the largest share. Therefore, the demand for packaging machinery in both international and domestic markets is huge. Such a large demand will also stimulate and stimulate the accelerated development of China's basic packaging industry
