Advantages of precoat film coating technology over coating

The glazing process can improve the glossiness of the surface of the printed matter. The printed waste after polishing can be recycled, reused or decomposed on its own, and does not pollute the environment. Therefore, the glazing process is favored by people in the industry. In particular, after the emergence of the UV coating process, some people began to think that the UV coating process will replace the coating process. In fact, this only saw the decorative effect of the coating process on the printed matter, and neglected the other functions of the coating. On the one hand, in terms of strength, the UV coating process hardly contributes to enhancing the strength of the printed matter, and the lamination process can increase the strength of the printed product by several times. On the other hand, with the advancement of technology, further processing after lamination, such as hot stamping and scrubbing, will further complicate the post-processing of printed matter. In today's era, intellectual property protection is emphasized, and businesses emphasize the anti-counterfeiting of products. Coating is more advantageous than UV coating.

Compared with the coating film coating process, what are the advantages of the precoating film coating process?
First, because the precoat film does not produce any harmful substances in the film a, the precoat film coating process is more environmentally friendly.

Second, the laminating film lamination process is simple, and it is not necessary to adjust the glue liquid like the laminating film lamination process before production. There is no need to control the amount of glue in the production process, no need to dry the adhesive. Only need to control the temperature, pressure and speed, the shutdown process is relatively simple, no need to clean the glueing mechanism.

Thirdly, bubbles, wrinkles, and stripping will not occur during production. Therefore, the quality of the film products will be higher.

Fourth, the scope of adaptation of the film-covering equipment is wide, and it is possible to use a precoat film coating equipment or a film coating equipment, and it is also possible to use a plastic sealing equipment.

Fifth, since no flammable substances such as organic solvents exist in the process of laminating the precoating film, it is possible to effectively prevent the occurrence of fire accidents in production, and the safety factor is higher.

Sixth, production efficiency is high.

Why is the film coating method still widely used in China?
Although the overall performance of the laminating film laminating method is better than that of the laminating film laminating method, judging from the current status of the domestic laminating film industry, most domestic enterprises still use the lamination film lamination process. The main reasons can be summarized as the following aspects.

First, the precoating film coating technology started relatively late in the country.

Second, the production of pre-coating film has high technical content, complicated process, large equipment investment, and the general enterprises are not capable of investing in pre-coated film production lines.

Third, due to the surplus of labor resources in our country and the low labor cost, the proportion of material costs in the overall cost of the coating process is quite large. The cost of the pre-coated film is higher than that of the coated film, which will inevitably affect its application.

Fourthly, the equipments produced by domestic film-covering equipment manufacturers are mostly film coating equipment.

Fifth, although the Chinese government emphasizes the environmental protection of the industry, the laws and regulations specifically targeting the film coating industry still need to be improved.
