When we visited the exhibition of books and magazines, it was difficult to see the products on the foreign booths with film coating. In some developed countries, the laws and regulations on environmental protection, health and fire insurance are relatively perfect, making it difficult to develop a film coating process. On the contrary, China's film market is showing a "prosperous" scene. To talk about the decoration of books and periodicals, we must talk about the film coating process.
         Although the regulations for disabling the solvent-based coating film process have been in place for many years, many small laminating plants are still in use in China. It is understood that this process mainly has the following problems.
         1. The laminating machine affects the health of the operator and there is a fire hazard.

         2. Solvent-based coatings use benzene-containing solvents to damage the health of operators and cause great pollution to the workshop environment. At the same time, as the concentration of the surrounding organic solvent continues to increase, it is extremely prone to sudden fire due to static electricity generated by the film material. And for the surrounding environment, the filming plant itself is a serious source of pollution, and there is a potential danger.
