First, because the pre-coating process does not produce any harmful substances, therefore, the pre-coating process is more environmentally friendly.

Second, the pre-coating process is simple, and it is not necessary to mix the glue like the instant coating process before production. there is no need to control the amount of glue in the production process, and there is no need to dry the adhesive. As long as the temperature, pressure and speed are well controlled, the shutdown treatment is relatively simple, and there is no need to clean the glue coating mechanism.

Third, in the production will not produce bubbles, wrinkles, film removal and other phenomena, therefore, the quality of film-coated products is higher.

Fourth, a wide range of adaptation to the coating equipment, can use pre-coating film coating equipment or that is, film coating equipment, but also can use plastic sealing equipment.

Fifth, because there are no combustible substances such as organic solvents in the pre-coating process, it can effectively prevent the occurrence of fire accidents in production, and the safety factor is higher.

Sixth, high production efficiency.

Why is the method of coating and laminating still widely used in China?

Although the comprehensive performance of the pre-coating method is better than that of the immediate coating method, according to the current situation of the domestic coating industry, the immediate coating process is still widely used in most domestic enterprises. The main reasons can be summarized as follows.

First, the pre-coating technology started relatively late in China.

Second, the production of pre-coated film has high technical content, complex process and large equipment investment, so ordinary enterprises do not have the ability to invest in pre-coated film production line.

Third, due to the surplus labor resources and low labor costs in China, the material cost accounts for a large proportion in the comprehensive cost of the film mulching process. The cost of pre-coating film is higher than that of pre-coating film, which is bound to affect its application.

Fourth, most of the equipment produced by domestic film coating equipment manufacturers are instant film coating equipment.
