Learn about the pre-coating system

The pre-coating film was used in 1989 and was mainly used in Europe and the United States. In 1996, it entered Asia. At the same time when it entered Asia, Europe and the United States announced the prohibition of the use of ready-to-use films instead of pre-coated films; Japan has now basically switched to pre-coated membranes. Other countries such as China, South Korea, and some countries in Southeast Asia are in the state of both coated and precoated membranes. It is only after 2000 that our country officially began to use precoating films locally. The development situation tells us that the coating process will certainly be eliminated in a very short period of time. It will be replaced by the precoating process technology. Once the pre-painted film is replaced by the entire film, it will be eliminated, which will eliminate a major source of pollution for our country and the world.

Of course, the elimination of paint films also requires a period of time. This process is first of all a shift in people’s consciousness. As long as we recognize the dangers of paint films and the importance of the interests of human environmental protection, we will accelerate the change and make our prints. The surface decoration technology of articles and articles has been raised to a new historical stage, and it has been brought into line with international standards as soon as possible and has been included in the international advanced level.

In order to solve the other problem of the filming process as soon as possible, that is to say, there is no paper film separation equipment in China, and the paper after coating is still not able to realize paper recycling. We can adopt two methods. First, we must seek for foreign advanced technology; The second is that the EVA hot-melt adhesive used for the pre-coated film is a re-adhesive adhesive material that can be separated and detached as soon as it is heated to the melting point. It calls for the development of China's manufacturing industry to develop paper-plastic separation equipment to thoroughly To solve the worries brought about by the laminating process, China's papermaking recovery rate has reached the international advanced indicators, creating a beautiful future for mankind. The development of postpress technology will be a future of automation, diversification, informationization, digitalization, and environmental protection. Let us work together to make joint efforts to create this beautiful future and make more contributions.
