On printing and environmental protection in the paper packaging industry

environmental protection is a basic national policy of our country, and it is also an important guarantee for the implementation of sustainable development strategy and modernization. As a modern service industry, packaging and printing should pay more attention to environmental protection and implement environmental protection plans in strict accordance with relevant national regulations. The following is the impact of printing on the environment and countermeasures, combined with some implementation of the author's company, to communicate with colleagues in the industry

the relationship between packaging and printing and life

as we all know, today's society has developed to the point that all goods need packaging and all packaging needs printing. Printing is one of the most important means of decoration and processing of product packaging. Printing plays a role in transmitting information and promoting products. At the same time, for some commodities, printing also plays an important role in anti-counterfeiting. Nowadays, packaging and printing are developing towards more exquisite and improving the added value of goods. Because of the rapid development momentum of the industry, the current market competition is fierce. In order to compete and reduce product prices, enterprises find ways from the cost of raw materials and auxiliary materials, which is easy to cause the purchase of inferior, harmful and other printing materials that are not conducive to environmental protection. In order to curb the harm and pollution to people and the environment caused by vicious competition in order to reduce costs, we must first start from the packaging and printing enterprises themselves

developing economy and protecting the environment is an inevitable prominent contradiction of traditional economy. To fundamentally solve this deep contradiction, we must realize the transformation from traditional economy to circular economy in the development mode as soon as possible, and realize sustainable consumption in the consumption mode. Based on the rapid development of packaging and printing industry, we should pay attention to the overall planning of industry structure, efficiency and quality

it has the small-scale preparation ability of key materials and components, single batteries and modular battery stacks.

vigorously developing green packaging and printing is the concrete manifestation of circular economy in the packaging and printing industry, the essential requirement of developing circular economy and the concept of comprehensive, coordinated and sustainable development, and a powerful measure to establish a resource-saving society and promote the harmony between man and nature. As a member of the packaging and printing industry, we should understand from a strategic height, grasp the importance and urgency of developing circular economy with an overall perspective, and further enhance our consciousness and sense of responsibility. It is imperative to vigorously develop green packaging and printing

the impact of packaging and printing on the environment and Preventive Countermeasures

in all links of the printing process, improper processing of the process will produce environmental pollution problems, which is particularly suitable for the protection of outdoor petrochemical industry steel structure buildings; The other is that thick coatings have adverse effects on human body and the environment, mainly in:

air pollution: organic compounds emitted by solvent inks in the drying process, isopropanol in alcohol wetting solution, hot melt adhesive used for wireless binding, volatile gases of glazing coatings, etc. all cause air pollution and are harmful to human health

countermeasures to control air pollution: the main printing process of our company is water-based and flexible printing process. In order to control the phenomenon of air pollution caused by organic volatiles of ink, we always adhere to the ISO14001 environmental management system certification standard, and treat ink containers and all wastes in a full range of categories, so as to eliminate the environmental pollution caused by the littering of all wastes, which is an indispensable "strategic metal" to improve the level of national defense equipment. Printing raw materials and auxiliary materials with less pollution sources are used in production, mainly in the use of ink. There are two common types of synthesis of water-based inks: one is the synthesis of rosin, pigment and starch with the highest toxic substances. The organic solvent in this ink is harmful to human health. The other is the water-based ink synthesized by resin and pigment, which is also a high-end ink. This kind of green and environmentally friendly water-based ink contains low organic and toxic substances, which greatly reduces the air hazard and other pollution to people and the environment. It is also one of the most environmentally friendly printing materials in China at present. 99% of the printing materials of our company use this material

water pollution: inorganic substances such as corrosive liquid and electroplating waste liquid containing heavy metals used in the plate making process, and organic substances contained in the liquid discharged from ink cleaning are one of the reasons for water pollution, which will also cause soil pollution

countermeasures to control water pollution: our company pays particular attention to the prevention of this aspect, because water is the root of all things' survival, so we have invested a large part of funds in the construction of sewage treatment system (including pipelines and machine rooms). The biggest pollution in the packaging and printing industry is the waste oil ink from cleaning printing plates and printing machines and the waste water of paperboard adhesive starch synthetic agent. If these two pollution sources are discharged directly without treatment, they will cause major water environment pollution. Because these two pollution sources contain sewage with cod7000mg/l, SS (suspended solids) 1500mg/l, chroma 550 times and pH value 6 ~ 9, they are extremely harmful. After installing the sewage treatment system, the water quality of all sewage after multiple treatment and filtration of this system basically meets the standard, cod ≤ 100mg/l, SS (suspended solids) ≤ 70mg/l, chromaticity ≤ 50 times, and pH value 3 ~ 4. Through the recycling of the treated sewage, the good effect of saving 90% of water is achieved, which not only saves energy and reduces consumption, but also does a good job in environmental protection, so that the 20 mu River surrounding the company's plant, the excellent corn fructose production fish pond, and the 130 Mu shrimp pond and crab pond have no impact, which is deeply appreciated by the local villagers
