On the development of green printing in China's pr

  • Detail

Talk about the development status of green printing in China's printing industry for a long time, China's printing industry, especially the packaging printing industry, has been developing extensively under high consumption and high pollution. However, with the fragility of the ecological system for human survival, the deterioration of the environment and the high lack of resources, both the resource stock and the environmental carrying capacity have been overwhelmed. Continuing to follow the road of traditional economic development can only slow down the process of China's modernization and hinder the healthy and sustainable development of the packaging and printing industry

green printing

green printing means that printing should have the awareness of environmental protection, strengthen the printing enterprises' awareness of environmental protection, vigorously promote the work of saving resources and energy, implement circular economy, and adhere to the scientificoutlookondevelopment

people in the printing industry should always adhere to the scientificoutlookondevelopment, pay attention to resource and energy conservation, unswervingly implement the circular economy, and pay attention to environmental protection. After all, what needs to go beyond the conventional configuration is to charge extra money to make the majority of printing workers further realize that in order to protect the ecological environment, save earth resources, be conducive to human health, benefit future generations, promote the sustainable development of China's national economy, eliminate the harm caused by environmental protection problems in printing, and then create a good living space for mankind

1 improve the legal system construction

2 vigorously develop and develop water-based ink, UV ink and other new inks that meet the requirements of environmental protection

3 using environmental protection technology to treat waste gas and wastes

4 strengthening the development and research of green printing, especially green packaging materials

5 optimizing green packaging design

6 government support

improving the legal system

we must establish and improve China's laws and regulations on green printing and green packaging in accordance with international practices. On the one hand, corresponding laws and regulations have been issued to limit the prominent environmental hazards in China's printing and packaging industry, such as strictly limiting the content of organic volatile compounds (VOC) in solvent based inks used in gravure printing, and the content of heavy metals such as lead, chromium, copper and mercury in some inorganic pigments in inks; On the other hand, for green printing, green packaging needs strong policy support from the government to shorten the gap with developed countries

vigorously research and develop water-based inks, UV inks and other new inks that meet environmental protection requirements

water-based inks are recognized as environmentally friendly printing materials in the world. Because water is transparent and has a variety of color choices, it is convenient for surgery to identify polar substances. According to the characteristics of polar substances and polar substances, water-based inks do not contain or only a small amount of organic solvents. Therefore, the greatest feature of water-based inks is to reduce VOC emissions, Thus, the pollution of volatile organic compounds is avoided, the printing environment is improved, and it is conducive to human health. It can completely eliminate the harm of some toxic and harmful substances in solvent ink to human body and the pollution of packaging products. It is especially suitable for packaging and printing products with strict sanitary conditions, such as food, beverage, medicine, toys, etc. In addition, it can also reduce the fire hazards caused by static electricity and flammable solvents, and reduce the residual solvent odor on the surface of printed matter

at the same time, develop water-based glazing process. Film covering and oily glazing will cause greater harm to the environment, while the diluent used in water-based glazing is non-toxic, tasteless and pollution-free water. From the perspective of environmental protection and human health, water-based glazing process undoubtedly has advantages

collect all kinds of wastes generated in the printing process, recycle the valuable articles such as paper, and recycle the materials that are difficult to degrade and harm the environment such as film and plastic film by the garbage recycling station for resource treatment or sanitary landfill

at this stage, due to the process and other reasons, we have to use various polluting printing materials, such as oil-based ink, oil-based film coating, oil-based glazing, etc. the harmful and toxic gases generated during their use can be treated by means of suction adsorption, recovery, device catalytic combustion, etc., so as to reduce the concentration of harmful gases in the working environment and reduce the harm to human body, At the same time, it also reduces the pollution of harmful gases to the environment

the emergence of paper packaging materials and new materials such as edible, degradable and recycled materials has eased the pressure on the ecological environment, reduced the depletion of oil resources, reduced environmental pollution, and solved the green barrier to China's export commodities caused by the international prohibition of the use of non degradable packaging materials. The extensive production and use of green packaging materials are of great significance both from the practical perspective of environmental protection and from the overall perspective of sustainable development of the national economy. It is also a concrete embodiment of the implementation of the scientific concept of development in the packaging and printing industry

packaging design should follow the design concept of harmlessness, ecology and reduction, and comprehensively evaluate the utilization of resources, environmental impact and solutions from the aspects of material selection, structure and function, manufacturing process, packaging method, storage form, product use and waste disposal

at present, environmental protection is a prominent issue concerned by countries all over the world. It involves not only major industries, but also the retail industry, service industry and even personal living habits. It is conceivable that in the next 10, 20 and 30 years, environmental protection will be a major prerequisite for all industries. It can be predicted that in order to effectively make the printing industry more environmentally friendly, suppliers and manufacturers will also launch new technologies in this regard. This not only refers to consumable products, but also new products will be launched on equipment or accessories. Therefore, we must anticipate the requirements of environmental protection in the future and meet the technological changes brought about by environmental protection in the future, Process flow transformation and management mode for environmental protection

vigorously developing green printing and green packaging is the continuation of the development of circular economy. Insiders pointed out that the quality requirements for the treatment and recycling of waste plastics in recent years are a powerful measure to establish a resource-saving society and promote the harmonious development between man and nature. The printing industry should understand it from a strategic perspective, grasp the importance and urgency of printing and environmental protection to develop circular economy with an overall perspective, and further enhance their consciousness and sense of responsibility
