Application of "Environmentally Friendly" Flexible Packaging Composite Adhesives (2)

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 introduced a solids content of 80% (YH2880) and 85% (YH2985); Henkel launched the UK2880 with a solids content of 80% adhesives, and these adhesives can be used at a working concentration of 40% or more. Coating, and not only the adhesive production technology is mature, but color printing companies do not need equipment to make big adjustments, 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.
