Introduction of several advantages of pre-coated film pre-coated film

Author:

First, because the pre-coated film coating process does not produce any harmful substances, the pre-coated film coating process is more environmentally friendly.
Second, the pre-coating film process is simple, and it is not necessary to adjust the glue solution like the coating film 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. Just control the temperature, pressure and speed, stop processing is relatively simple, no need to clean the glue coating mechanism.
Third, in the production will not produce bubbles, wrinkles, film and other phenomena, therefore, the film product quality is higher.
Fourth, the adaptation of the coating equipment is wide, you can use pre-coating film coating equipment or coating film equipment, but also can use plastic packaging equipment.
Fifth, because there are no combustible substances such as organic solvents in the pre-coated film coating process, it can effectively prevent the occurrence of fire accidents in production, and the safety factor is higher.
Sixth, the production efficiency is high.
Why is that the film coating method is still widely used in China? Although the comprehensive performance of the pre-coating film coating method is better than that of the film coating method, but the current situation of the domestic film industry, the vast majority of domestic enterprises are still in the general use of the film coating process. The main reasons can be summarized in the following aspects.
First, the pre-coating film technology started relatively late in China.
Second, the production of pre-coated film technology content is high, the process is complex, equipment investment is large, the general enterprise does not have the ability to invest in pre-coated film production line.
Third, due to the surplus of labor resources and low labor costs in China, material costs account for a large proportion of the comprehensive cost of the laminating process. The cost of the pre-coating film is higher than that of the coating film, which will inevitably affect its application.
Fourth, the equipment produced by domestic manufacturers of laminating equipment is mostly film laminating equipment.
Fifth, although the Chinese government emphasizes the environmental protection of the industry, the laws and regulations specifically for the film industry need to be improved.
