Since solvent-based coatings are so dangerous, why are there still such a large market? The reasons for this are more or less determined for the following reasons.
          First, the laminating machine with solvent-based adhesive has been used for many years, the development of the equipment has been very mature, and the filming precision is guaranteed. These machines are generally not easy to be damaged, the maintenance is not complicated, and many productions have accumulated in long-term use. And maintenance experience, so many manufacturers are reluctant to eliminate this solvent-based laminating machine that can also come in handy.
         Second, the solvent-based laminating process has been promoted for decades, the technology is mature, and the product quality is guaranteed. Many companies and technicians are reluctant to replace a skilled craftsmanship with a technology that they are not familiar with.
         Third, from the cost point of view, solvent-based laminating machine is still relatively cheap, for the printing plant, cost savings is to fight for profits.
         Fourth, the water-based laminating machine laminating process improves the environmental problems in the production process and avoids damage to the operator's body. However, there are still many defects compared with the solvent-based laminating process, such as product quality is difficult to make people Satisfied.

         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.

          Paper and film materials after laminating machine laminating are difficult to recycle, wasting resources
          It is understood that 80% of the source of papermaking fiber in China now relies on the recycling of used paper, including paper and paper. In the printed matter, the amount of paper used for the cover of the book is also huge. If the film is applied in large quantities (especially the ready-coated film material), the paper and the plastic film cannot be separated.
          Then the waste paper covered by the laminating machine and the paper edge and paper wool will not be recycled and cannot be degraded. This will bring an unpredictable economic loss, which is actually a waste of resources.

          The laminating process is widely used in various types of packaging and decoration printed matter in China, and books, magazines, calendars, maps, etc. in various binding forms are a very popular surface processing technology for printed products. The film-coating process entered China in the 1980s. Due to its many advantages, it has swept the country in a very short period of time and has gradually become the darling of the surface decoration of books and periodicals.
          Nowadays, people's awareness of environmental protection is gradually increasing, relevant laws and regulations are constantly improving, and the pollution caused by the laminating process and the difficulty of reusing the coated products when they are discarded are in front of people. When the laminating machine is lifted, people tend to Think of "white pollution." Many in the industry have doubts about the function of the film and its continued application.
          It is certain that in the future development process, the film coating technology will accept more and more tests. How will the film develop? Is it completely eliminated or rationally developed? These problems will become unavoidable problems in the development of the laminating process.

The characteristics of the instant coating:
(1) It is prone to foaming and film detachment. In large-area solid printing or high humidity working environment, foaming and film removal are particularly serious.
(2) The surface of the product often produces bright spots or fog points with different gloss.
(3) The product is prone to curling. If the pressure is too high when the glue is applied or the temperature is too high during drying, the curling phenomenon is more serious.
(4) Chemical substances such as organic solvents will volatilize into the atmosphere when the laminator is coated, causing environmental pollution and even causing fire.
