The development trends of coating materials have a profound impact on the packaging printing industry. On the one hand, as coating materials develop towards environmental protection and high performance, packaging printing enterprises need to constantly update their equipment and processes to adapt to the application of new coating materials. For example, the increased use of photocuring equipment to adapt to the use of photocuring materials such as UV embossing aluminum varnish and 172nm excimer coatings will improve production efficiency and reduce environmental pollution. On the other hand, the multi-functional and high-precision development of coating materials has prompted the packaging printing industry to constantly innovate, enabling it to provide brands with more distinctive and value-added packaging solutions, such as using photoresist and other film surface coatings to produce high-precision anti-counterfeiting and decorative coatings, improving the quality and competitiveness of packaging. At the same time, the development of coating materials has also driven the packaging printing industry towards digitalization and intelligence, in order to better control the application process of coating materials, achieve precise coating, curing and quality inspection, and meet the growing market demand for packaging and printing products.

Some coating materials have anti-counterfeiting functions. Photoresist and other film materials can be used with photolithography to create patterns with microstructures or special optical effects, such as holographic patterns and microlens arrays. These patterns are difficult to replicate and have strong anti-counterfeiting properties. Some UV-embossed aluminum varnishes can also use special embossing processes to create coatings with unique textures or optical changes, increasing the anti-counterfeiting performance of the packaging. In addition, special anti-counterfeiting additives, such as fluorescent powder and thermochromic pigments, can be added to the coating materials, allowing the coating to exhibit different colors or luminescence effects under specific lighting conditions, achieving anti-counterfeiting functionality. Through these methods, coating materials can provide effective anti-counterfeiting protection for high-end tobacco and alcohol packaging, preventing the appearance of counterfeit and substandard products.

Different coating materials have different processing requirements in packaging printing. Water-based plastic substitute oil needs to pay attention to drying conditions. Because it uses water as a solvent, the drying speed is relatively slow. It usually requires appropriate heating and ventilation conditions to accelerate the drying process. At the same time, the coating amount and coating uniformity should be controlled to ensure the coating quality. UV embossing aluminum varnish and 172nm excimer coatings require specialized UV curing equipment to accurately control parameters such as the time, intensity, and wavelength of photocuring to ensure that the coating can be cured quickly and completely. At the same time, attention should be paid to the precision of the embossing process to achieve the ideal pattern and texture. The process requirements for coating materials such as photoresist are more complex, involving multiple steps such as photolithography, development, and etching. It is necessary to strictly control the process parameters of each link, such as the exposure dose of photolithography, development time, and temperature, to ensure the precision and quality of the coating and meet the strict requirements of high-end tobacco and alcohol packaging for details and precision.
