The glazing process can improve the glossiness of the surface of the printed matter. The glazed printed matter waste can be recycled or decomposed by itself without polluting the environment. Therefore, the glazing process is favored by people in the industry. Especially after the appearance of the UV glazing process, some people began to think that the UV glazing process would replace the laminating process. In fact, this just saw the decorative effect of the laminating process on the printed matter, while ignoring the other functions of the laminating process. On the one hand, in terms of strength, the UV glazing process has little contribution to enhancing the strength of the printed matter, while the laminating process can increase the strength of the printed matter several times. On the other hand, with the advancement of technology, further processing after laminating, such as hot stamping, matte, etc., will make the post-processing process of printed matter more complicated. In today ’s era where intellectual property protection is emphasized and merchants emphasize product anti-counterfeiting, Laminating has advantages over UV glazing.
What are the advantages of the pre-coating film coating process compared to the instant coating film coating process?
First, since no harmful substances are produced during the precoating process, the precoating process is more environmentally friendly.
Second, the pre-coating film coating process is simple, and there is no need to mix the glue before production like the immediate coating film coating process. There is no need to control the amount of glue applied during the production process, nor to dry the adhesive. You only need to control the temperature, pressure and speed, and the shutdown process is relatively simple. There is no need to clean the glue application mechanism.
Third, bubbles, wrinkles, and peeling will not occur during production. Therefore, the quality of the coated products is higher.
Fourth, it has a wide range of adaptation to laminating equipment. Pre-coating or laminating equipment can be used, and plastic packaging equipment can also be used.
Fifth, since no flammable substances such as organic solvents exist during the pre-coating process, it can effectively prevent the occurrence of fire accidents in production, and has a higher safety factor.
Sixth, high production efficiency.
Why is the instant film coating method still widely used in China?
Although the overall performance of the pre-coating film coating method is superior to the instant-coating film coating method, in view of the current status of the domestic coating industry, the vast majority of domestic companies are still using the instant-coating film coating process. The main reason can be summarized as the following aspects.
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 investment in equipment. The general enterprises have no ability to invest in the pre-coated film production line.
Third, due to China's surplus labor resources and low labor costs, the cost of materials accounts for a large proportion of the overall cost of the laminating process. The cost of the pre-coated film is higher than that of the coated film, 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 need to be improved.
