Encyclopedia says that environmental protection generally refers to the general term for human actions to solve real or potential environmental problems, coordinate the relationship between humans and the environment, protect the living environment of human beings, and ensure the sustainable development of the economy and society. So what is the environment we are living in now?
The Ministry of Environmental Protection recently announced that the fourth batch of central environmental protection inspection teams completed the inspectors of eight provinces (districts) including Jilin, Zhejiang and Shandong. So far, from the end of 2015, the central environmental inspection inspector started from the pilot in Hebei, covering 31 provinces (autonomous regions and municipalities) in two years. The scope of supervision is not wide; more than 15,000 people are held accountable, and the accountability is not too big. . I would like to ask, what kind of scene has this environment become, so that such a large-scale inspection action will be on the land of China? I think everyone has a clear answer in mind!
Pollution control action
Environmental pollution will cause direct damage and impact to the ecosystem. For example, desertification and forest destruction will also cause indirect harm to human society. Sometimes the harm of this indirect environmental effect is greater than the direct harm caused at that time. Hard to eliminate. According to the source of the nature of environmental pollution can be divided into: chemical pollution, biological pollution, physical pollution (noise pollution, radioactive pollution, electromagnetic pollution, etc.), solid waste pollution, liquid waste pollution, energy pollution, light pollution.
Practice the concept of environmental protection, ink packaging is also crazy
Nowadays, all walks of life around the world are actively practicing environmental protection concepts. Our printing and packaging industry is no exception. As the important consumables in the printing production process, the greening of the packaging used by itself is also very large. attention.
Tin can packaging ink will gradually fade out of the market stage
In the early days, inks were basically in the form of iron cans. They have been used for hundreds of years and become the universal ink packaging method for the global printing industry. Iron can packaging has good mechanical properties, high strength, good rigidity and is not easy to break, so it is more convenient in transportation and storage; excellent barrier property, good gas barrier, moisture resistance, shading, fragrance, and Its good sealing property can insulate the ink from oxygen, making the ink difficult to crust and the molecules remain stable. The excellent advantages of these cans are designed to optimize the printability and rheology of the ink.
However, after the ink packaged in the cans is used up, it usually produces about 5% of residual ink. In fact, no matter how the residual ink is disposed, it will eventually become waste of toxic and solid waste. According to incomplete statistics, the annual consumption of ink cans in the world has been between 3.5 billion and 400 million (including offset and gravure), and the annual average consumption of ink cans is about 1.5 billion. The tank caused a large amount of toxic solid waste. These toxic solid wastes not only bring high processing costs to the printing enterprises, but there are still many problems in the treatment of the substances, which will cause great harm to the environment. In small packages of iron cans, up to about 7% of the ink remains in the ink tank after use. This wasted ink not only pollutes the environment, but also increases the production of the enterprise invisibly. cost.
Plastic packaging ink pollution problem is still difficult to crack
Plastic packaging is one of the four major materials in the packaging industry. It has low density, high specific strength, high packaging yield (ie, unit mass of packaging volume or packaging area), good chemical resistance, and long-term placement is not easy to oxidize. Low cost, good insulation and so on. Plastic packaging has been widely used in many industries such as electronics, food, beverages, medicine, etc. for a long time, and is still an indispensable material.
However, the garbage pollution caused by plastic packaging is a major culprit in polluting the environment and destroying the ecology. The biggest feature of plastic waste is that it is difficult to degrade. The current mainstream treatment methods are landfill, incineration, etc. It not only forms marine and land pollution, but also enters the human body in the form of plastic particles or chemicals. The plastic packaging ink needs to be used up in the open bag, which does not have much impact on the production of uninterrupted live parts. However, as long as the equipment is stopped, the ink is faced with the problem of crust, so it takes a lot of time to store the remaining ink. Brains. In addition, plastic packaging inks are not yet intelligent enough to be added. It is necessary to manually replace the ink bags, and the bags must be removed after the ink is squeezed. In fact, the purpose of saving labor costs is not fundamentally achieved.
Paper bag packaging ink
In order to better combine environmental and economic benefits, the industry has locked the packaging material on paper. As is known, paper is a resource that can be recycled and reused. Paper packaging has the advantages of easy processing, low cost, light weight, foldability, non-toxicity, odorlessness and pollution-free. Paper bag packaging technology stores ink in paper packaging for storage and use, and skillfully uses the paper processing plant's ability to process ink on the surface of printed matter during waste paper recycling, so that the contaminated waste becomes a renewable resource, thereby reducing environmental pollution. To the lowest. In addition, the use of paper bags to package ink can increase the filling efficiency several times before, directly increasing the ink supplier's production capacity. At the same time, due to its flat paper packaging shape, transportation space and storage efficiency are greatly saved.
At present, the paper packaging ink R & D manufacturers in the industry can already do it. The ink bag after the ink is squeezed out expands only the size of A4 paper, and directly enters the waste paper processing link of the printing factory. It not only saves the cost of solid waste disposal of iron cans, but also greatly reduces ink residue. On average, a bag of 2 kg of ink, after the use of paper bags, the residual amount of ink can be reduced to about 4 grams, reducing the amount of ink waste is also more conducive to environmental protection, helping printing companies save a considerable economic cost.

For most printing companies today, paper-wrapped inks have been able to solve most of the waste disposal problems, but there is room for further improvement. For example, ink packaging with paper materials, the outer packaging is too thin, there may be a small probability of breaking the bag and crust, which is not conducive to transportation and long-term storage; there is still a lack of use and intelligence, The paper bag after the ink is squeezed still needs to be manually torn. If this step is not carried out, the ink in the bag is not easy to dry, and the hazardous waste treatment is still inevitable.
Paper-type packaging ink New round of changes shocked
The industry has been trying to make a revolution in ink packaging through a more environmentally friendly and efficient way, so that the paper-type packaging ink that can make up for the lack of ink in the packaging of the paper bag came into being. The outer packaging of the paper tube is thicker, which effectively solves the drawbacks of the storage and transportation of the paper bag packaging. In addition, the paper-type packaging ink utilizes a small extrusion device, which can be used in a number of ways, without manual guarding, and achieves complete intelligence, thereby saving labor costs.
According to Xiaobian, at present, the paper-type packaging ink can reach 10 kg per barrel, and the storage capacity is increased, which solves the problem of frequent ink replacement. After use, it can achieve no residue in the package, the inner wall of the paper tube is very clean, and the amount of residual ink is negligible compared with the residual ink volume of the paper bag. It can be dried by natural oxidation, and the paper after use. The canister can be used as waste paper waste treatment, and truly make the printing companies have no worries!
The paper-type packaging ink can not only reduce labor costs for the majority of printing enterprises, but also has good environmental performance, which can reduce the cost of hazardous waste treatment and effectively increase the economic benefits of enterprises. It is reported that Suzhou Bolai Te Ink Co., Ltd. is the first ink manufacturer in China to adopt paper tube packaging. It is foreseeable that paper tube packaging ink will be promoted in the market with greater intensity and scope. Pushing the printing industry has become a model of environmental protection.
