Why the instant coating method is still widely used in China. Although the comprehensive performance of the pre-coated film is better than the instant coating method, the current domestic coating industry is the most domestic enterprises. The instant coating process is still widely used. The main reasons can be summarized as follows.
First, the pre-coating film technology started relatively late in China.
Second, the pre-coating film for the production of laminating machine has high technical content, complicated process and large equipment investment. The general enterprise has no ability to invest in the pre-coating film production line.
Third, due to China's surplus labor resources and low labor costs, material costs account for a large proportion of the total cost of the laminating process. The cost of the pre-coating type is higher than that of the coating type, which will inevitably affect its application.
Fourth, most of the equipment produced by domestic laminating equipment manufacturers are instant coating laminating equipment.
Fifth, although the Chinese government emphasizes the environmental protection of the industry, the laws and regulations specifically for the laminating industry have yet to be improved.
