"Environmental protection, health, safety" is a global topic and a problem that all industries are concerned about. The adhesive used in the flexible packaging industry has always been one of the core issues discussed in relation to “environmental protection, health, and safetyâ€. This is mainly because flexible packaging has the advantages of convenience, high efficiency, and versatility, and has been used in depth, extensively and extensively. This also makes its impact on the environment, health, and safety more and more significant, and has increasingly attracted people's attention.
Europe and the United States have been at the forefront of the global application of flexible packaging composite adhesives, and (a) this has always been a leader in Asia, especially dry compounding, as it has adapted to the widest range of material functional complementarities, compounded for decades. The rapid development of materials has brought about tremendous changes in the umbrella ball packaging industry. The technology and production of two-component polyurethane adhesives also tend to mature, and its excellent performance, wide adaptability, and low price can meet almost all the requirements of flexible packaging composites, Shenzhen adhesiveness, softness, heat resistance, cold resistance It can be used to pack all kinds of acid, spicy, salty, sweet, oily foods, cosmetics, composites, anti-media, transparency, flowability, initial tackiness, anti-ultraviolet radiation and sizing operability. Even pesticides containing DMF, so users of packaging in various countries are very happy with the Xianchuan bicomponent 1) u adhesive, but it has three fatal shortcomings that have led to it eventually will reduce the application, if possible, people will again I'm happy to see it exit the packaging stage. First of all, in the composite processing process, a large amount of solvents must be discharged to pollute the environment. Secondly, the composite material contains trace amounts of residual solvent, and Liu Weijue produces cattle. In addition, residual TDI has a consensus on the human health hazards.
Although the world's technological information is circulating rapidly, the roads adopted by different countries are still very different and form a unique R&D and market. For example, in Europe, the research of polyurethane water dispersion adhesives and solventless adhesives is at the forefront, and the market has also developed rapidly. In the United States, reactive hot melt adhesives develop faster. In short, all countries in the world are actively exploring alternative varieties. At the present time, it can be concluded that: Great progress has been made in replacing the two-component solvent Pu, but we have yet to find a comparable product. The environmentally friendly safety material replaces it. Specific reactions to the market, see this phenomenon, First, the demand for solvent-based polyurethane adhesives is still rapid development, the absolute amount of growth is much higher than other types of adhesives growth; Second, in some areas is limited to certain Industrial areas, especially solvent adhesives, hot-melt adhesives, water-based polyurethane adhesives, alcohol-soluble polyurethane adhesives have a faster growth; Third, for the "green adhesive" must from the "safety, environmental protection, health "Comprehensively resolved in three areas, and the current "green adhesive" is still difficult to give people a more comprehensive sense of security. You can see Table 1.
At present, the production time of adhesives in China's flexible packaging industry is very short. Through these years of competition, a large number of technical research personnel have been trained. The experience in polyurethane adhesive technology research has been almost exclusively focused on two-component polyurethane adhesives. . Domestic adhesive companies have matured in the production and application of aromatic solvent-based two-component polyurethane adhesives, and have occupied nearly all of the market share of ordinary adhesives. This is made at a price lower than that of imported brands and it is extremely difficult. On functional adhesives, the successful development of Beijing Gaomeng Chemical Co., Ltd. YH3640 is of great significance. In other words, in the field of flexible packaging aromatic solvent-based two-component polyurethane adhesives, domestic enterprises can be all aspects of the world - Streamline industry competition. The market demand for such adhesives will also increase rapidly rather than shrink, which is the first priority. However, the growth of environmentally friendly adhesives is also accelerating, and it eventually occupies a certain share. In addition to the exploration of individual companies in alcohol-soluble polyurethane adhesives, the research and production of other alternative products are almost blank. Adhesive companies with strong domestic technology, such as: Beijing Gaomeng Chemical Co., Ltd. in water-based adhesives, solvent-free; Beihuayuan in solvent-free; Europe and the United States in alcohol-soluble adhesives; Rohm and Haas in water-based polyurethane Adhesives, etc. have made certain technical reserves and actively promoted the market. Here, I would like to discuss under the current circumstances of our country, market conditions, management conditions and the conditions of China's soft bag, under the "environmental protection, health, safety", the domestic adhesive companies and flexible packaging industry how to go.
First, through the simple process of Liu Xiang change, the use of ultra-high solid binder to the concentration of the binder mentioned more than 40%, reduce the volatilization of solvents, thereby reducing environmental pollution Liu. More than 60% of the adhesives are ordinary adhesives, no special requirements, the domestic generally use 50%-75% solids content of the adhesive, working concentration between 25% -35%. Beijing Gao Meng launched a solids content of 80%
(YH2880), 85% (YH2985); Henkel launches UK2880 with 80% solids binder. This type of adhesive can be coated at high speeds of more than 40%, and not only adhesive production technology. Mature, and color printing companies do not need to make big adjustments to the equipment, just change the cable roller. The current level of technology can be completely achieved. With the current annual usage of adhesives of 10,000 tons, with a working concentration of 25% to 35%, there will be at least 5.7 million to 80,000 tons of ethyl esters. Wasted and discharged directly into the environment. If 40% of the working concentration is mentioned, the consumption of ethyl ester will be only 50,000 tons, and there will be less chlorate emissions from 0.7 million to 30,000 tons and pollution to the environment. This is surprising.
2. In 2004, all adhesive companies in the country were extremely difficult. Due to the sharp increase in international oil prices, the raw materials used in adhesive production were substantially increased. In October 2004 and in the same period in the year, Liu Bi and B Ester, diethylene glycol, MDI, and TDI rose by 160%. 80%, 190%, 110%. The sales of ordinary adhesives are almost all on the cost line, so sit down with the corporate bosses of adhesives and talk about almost all the problems that exist. But things must also be viewed from two perspectives. We must also see that this brings with it tremendous opportunities. The integration of adhesives manufacturers is approaching (this is not what this article discusses). On the other hand, color printing companies are The impact of the sharp rise in ethyl ester prices, electric sober saw the huge difference in the price of ethyl ester and water. Color printing companies have also taken actions to actively cooperate with and explore the application technology of water-based PUs. Water-based PUs and market applications were advanced under the impact of 2004. If you can seize this opportunity in time, it will bring tremendous development to the adhesive companies. Otherwise, 2005 will be a year when international companies have a water-based PU business. Among domestic adhesive companies, Beijing Gaomeng's water-based polyurethane adhesives have entered the market, which will be a bright spot in 2005. It is hoped that more adhesive companies will join in, making waterborne polyurethanes sticky. The mixture matured quickly. The same is true for solvent-free applications. In the domestic market, Henkel and Norwich have played a leading role. In 2005, more than half of the nearly 30 production lines in domestic color printing companies will be brought into play. It is hoped that domestic adhesive companies can join the ranks of sub-cakes. Gradually, only two varieties of aliphatic binders entered the market in Beijing Gaomeng.
In short, 2005 is the year when environmental friendly adhesives truly enter the market. Water-based, alcohol-soluble, solvent-free, and aliphatic binders will all increase significantly. Domestic companies will also compete with international companies in this area.
