In today’s society, peace and development are the two major trends in the development of the world. In the world economic growth, the environmental protection industry has become a new economic growth point. The packaging industry has gradually grown with the development of social industrialization and is an inevitable trend of social and economic sustainable development. Packaging, environmental protection and economic sustainable development are closely linked, complement each other, and promote each other's development. As an important industry that accounts for approximately 1.7% of the national economic development, packaging should even take on this sacred mission, sublimate environmental protection to a higher level, and promote the development of packaging and post-press processing in the direction of environmental protection. A new wave of green environmental revolution.
The environmental protection packaging industry in China is in the ascendant, and the development prospects are very broad. The potential market is very large, and the potential market has gradually transformed into a real market. The environmental protection packaging industry will surely become a new growth point for the national economy. At present, China's environmental packaging industry has begun to take shape. Driven by the concept of environmental protection, environmental protection packaging springs up and thrives. For example, many large and medium-sized packages and printing companies in China are using advanced foreign packaging and printing equipment. According to statistics, as far as flexographic printing presses are concerned, by 1999, China had introduced more than 100 articles in more than 100 packaging and printing companies in 22 provinces, autonomous regions, and municipalities directly under the Central Government, and in coastal cities with rapid economic development. More common. These high-efficiency and advanced production equipment not only saves a lot of manpower and material resources, and reduces the consumption of resources and the pollution of the surrounding environment, but also adds unprecedented vitality to the value of the national product itself and enhances it. Domestic and foreign market competitiveness. These fully reflect the development trend of environmental protection in China's printing and packaging industry, environmental protection packaging and printing awareness has been deeply rooted.
Although high-efficiency and environmental-friendly advanced production equipment has been introduced into the Chinese packaging and printing industry with the spring breeze of reform, there are still some problems in the packaging and printing industry. These problems are mainly manifested in the vicious circle of the material supply chain in the process of packaging and printing. For example, some domestic packaging and printing post-processing companies are still using backward processing equipment introduced in the 1960s or the 1970s. The resulting process is behind, and the backward technology and equipment defects cannot be combined with efficient and environmentally friendly materials. If it is used, it will, to a certain extent, increase the cost of procurement and processing of the product, making the profit of the manufacturer low, and not worth the candle. The resulting low-price competition has led producers of processed materials to ensure their own survival at low prices. They have to use inferior and cheap materials, which not only aggravates the pollution of the production process, but also wastes a lot of manpower and material resources. And it poses a great threat to the social environment. In view of the current situation and existing problems in China's packaging and printing industry, we must vigorously popularize the use of environmentally friendly packaging and printing materials, and must ensure that the entire supply chain of packaging and printing meets the requirements of environmental protection and energy conservation. We can no longer stick to only pay attention to tangible pollution instead of focusing on the growth of intangible pollution, neglecting the role of supply chain factors, and holding the idea of ​​only sweeping the door, regardless of the pressure and harm caused to the environment. From the perspective of sustainable development model, we must achieve comprehensive energy conservation and environmental protection, and avoid the metaphysical, vulgarization, and simplification of environmental packaging printing.
So how do we properly deal with the relationship between the packaging printing process and environmental protection? We believe that the following method, the 5 "R" principle:
REDUCE: Reduce the use of materials. In ensuring the protection, transportation, storage and sales of packaging, the first consideration is to minimize the total amount of material used. Research has found that the best packaging for the environment is the one with the least amount of use.
REUSE: Use it again. Considering that all or part of the packaging is used after use, recycling and reuse will not result in environmental pollution and waste of resources. RECYCLE: Recycling treatment. The used packaging is recycled, processed, processed and used in different fields.
RECOVER: Get new value. For example: Recovering waste by incineration to obtain its energy, or obtain new value by degrading packaging.
RESOURCE: Save energy. Pay attention to energy conservation in all aspects of packaging and printing processing, and try to avoid resource waste.
The application of the above five principles in the packaging and printing process is of great significance.
China's current packaging and printing after the main performance of the film, coating, die-cutting, electrochemical, aluminum hot stamping and other processes. If these equipments are used in the sixties or seventies, they are complicated and numerous. However, if you use various high-tech advanced equipment at home and abroad, it will be relatively simple and fast, high-speed economy, energy consumption, waste of materials, and production. Significant increase in efficiency, lower product processing costs, to achieve good packaging, high value-added purposes. As for the two common processes of lamination and glazing, we should try to reduce the post-printing lamination. Solvent-based film should be completely eliminated. It not only pollutes the atmosphere, but also damages people's physical and mental health, and greatly increases the hazards of factory fires. Replaced by water-based wet, water-based dry film and pre-coated film. Of course, the best way is that packaging and printing should actively transition to a variety of water-based glazing, namely: water-based wet infrared glazing, water-based wet UV glazing and water-based calendering. This not only has the advantages of film coating, but it is also very quick and easy in the production process, especially in flexo printing or on-line coating systems, without any pollution, and recycling, degradation, etc. are very convenient and feasible. This is the mainstream of the development of social packaging printing, of course. A certain amount of investment.
Packaging and printing not only requires environmental protection in the production process, but also requires the use of various environmentally friendly materials in the production process, that is, environmental protection in the material supply chain, and ultimately makes it easier for packaging and printing products to be recycled and reused. Huaqing Debang Waterborne Varnish, Waterborne UV Varnish, Waterborne Varnish, Waterborne Laminate Adhesive and Adhesive, jointly produced by Australian MNC Company and Guangdong Huaqing Industrial Company. Not only adopts advanced production technology and equipment for production, but also the product fully complies with international environmental standards. The vigorous promotion and use of these products in China's packaging and printing industry will play an important role in promoting the development of environmental protection packaging printing in China.
Green packaging generally refers to packaging that is harmless to the ecological environment and human health, can be reused or recycled, and conforms to the principle of sustainable development. Even the best packaging, if it is discarded or not recycled, can cause harm to the environment, and it is difficult to call it a green package. The key to the study of the significance of green packaging is to strengthen the effective control of the packaging printing production process. Recycling of packaging waste. Packaging printing is a means to solve environmental problems, not itself.
China's economic construction has made brilliant achievements, and environmental protection packaging and printing have contributed to it. However, the negative impact of packaging and printing on the environment has also been gradually recognized by people. We packaging people must do a good job in the healthy development of environmental protection packaging and printing processing, not only to vigorously promote The use of highly efficient and environmentally friendly advanced production equipment, and the use of environmentally friendly materials in all aspects of production, is more important in calling for the people to carry out environmental protection because environmental protection is the condition for the entire society and for the survival of all humanity. The ecological environment is the most basic element of human survival. Protecting the ecological environment and creating a green and protective world are the responsibility of the packers and the common mission of all mankind.
