Since solvent-based coatings are so harmful, why is there still such a large market? The following reasons more or less determine the reason for its existence.
First, the laminating machine using solvent-based adhesives has been used for many years, the development of the equipment has been very mature, and the laminating accuracy is guaranteed. These machines are generally not easy to break, maintenance is not complicated, and have accumulated a lot of production in long-term use And maintenance experience, many manufacturers are reluctant to eliminate such solvent-based laminators that are still useful.
Second, the solvent-based coating process has been popularized for decades, the technology is mature, and the product quality is guaranteed. Many companies and technicians are reluctant to replace a skilled process technology with a technology that they are not very familiar with.
Third, in terms of cost, solvent-based laminators are still relatively cheap. For printing companies, cost savings is to win profits.

Fourth, although the laminating process of the water-based laminating machine improves the environmental problems in the production process and avoids harm to the operator's body, it still has many defects compared with the solvent-based laminating process. For example, the product quality is difficult to make Satisfied etc.
