The glazing process can improve the gloss of the printed surface, and the glazed printed waste can be recycled or decomposed by itself, without polluting the environment. Therefore, the glazing process is favored by the industry. Especially after the UV glazing process, some people began to think that the UV glazing process would replace the laminating process. In fact, this only saw the decorative effect of the laminating process on the printed matter, while ignoring the other functions of the mulching film. On the one hand, from the strength point of view, the UV glazing process has little contribution to the strength of the enhanced print, while the film coating process can increase the strength of the print several times. On the other hand, with the advancement of technology, further processing after lamination, such as hot stamping and sanding, will make the post-processing of printed matter more complicated. In today's era of emphasizing intellectual property protection, merchants emphasize product anti-counterfeiting. The film is more advantageous than UV glazing.
What are the advantages of the precoat film coating process compared to the instant film coating process?
First, the precoat film coating process is more environmentally friendly because no harmful substances are generated during the precoat film coating process.
Secondly, the pre-coating film coating process is simple, and it is not necessary to adjust the glue liquid as before the film coating process. There is no need to control the amount of glue applied during the production process, and it is not necessary to dry the adhesive. Just control the temperature, pressure and speed, and the shutdown process is relatively simple, no need to clean the glue coating mechanism.
Third, there is no phenomenon of bubbles, wrinkles, and film peeling during production. Therefore, the quality of the film product is higher.
Fourth, the coating equipment has a wide range of adaptation, and a pre-coating film laminating device or a coating film laminating device can be used, and a plastic sealing device can also be used.
Fifth, since there is no combustible substance such as an organic solvent in the precoating film coating process, it is possible to effectively prevent the occurrence of a fire accident in production and have a higher safety factor.
Sixth, the production efficiency is high.
Why is the film coating method still widely used in China?
Although the comprehensive performance of the precoat film coating method is better than the film coating method, the current state of the domestic laminating industry, the majority of domestic enterprises are still using the film coating process. The main reasons can be summarized as follows.
First, the pre-coating film coating technology started relatively late in China.
Second, the production of pre-coated film 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 the surplus of labor resources in China, the labor costs are low, and the material cost accounts for a large proportion of the comprehensive cost of the laminating process. The cost of the pre-coated film is higher than that of the film, which will inevitably affect its application.
Fourth, most of the equipment produced by domestic laminating equipment manufacturers are coating film 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.
