The Revolution of Snowflake Ink Technology by UV Curing Resin: Giving Packaging A "Wear-resistant Snowflake Coating"
Walk into any premium distillery's packaging hall, and you'll witness alchemy. When the press rolls, liquid crystal-clear ink kisses gold-foiled designs. Then—the reveal. Under UV lamps, that ink blooms . Not violently, but like frost crystallizing on a January windowpane. In seconds, a lacework of ice fractures across the surface. Run your thumb over it: cold winter illusion meets industrial-grade toughness. This is "snowflake ink"—where photochemistry meets luxury. And now, thanks to next-gen UV resins, it’s not just pretty; it’s built to last.
1. Snowflake Ink: The "Makeup Artist" of Luxury Goods in Light and Shadow
Snowflake ink (also known as freezing point ink) is a functional coating material that creates a snowflake-like or ice-cracked effect on the printed surface. Its unique characteristic is that after printing, upon UV irradiation, it spontaneously generates a transparent, three-dimensional raised texture, creating a crystal-clear visual and tactile effect. It is widely used in packaging decoration for high-end tobacco, alcohol, cosmetics, and health supplements.
Traditional snowflake inks are often printed using screen printing, which suffers from low efficiency, high cost, and difficulty adapting to the high-speed production of offset printing. More importantly, to achieve the desired "snowflake" texture, formulations often limit the addition of reinforcing particles, resulting in insufficient wear resistance and adhesion after film formation, making it susceptible to damage and scratching during subsequent processing or logistics.
2. Ever Ray's Customized Solutions
The performance of snowflake ink is extremely sensitive to the formulation structure. Conventional adjustments to the formulation often fail to meet standards (e.g., fineness and burst point size control). Ever Ray adheres to a "one customer, one formula" approach, customizing resins to meet specific application requirements to ensure product performance meets standards.
Currently, outstanding UV-curable resins for snowflake inks include:
13215B, 13216A-6, 1321E-1F, and 7317. These resins offer excellent burst point control and film-forming mechanical properties, and are currently the primary focus.
3. Future Outlook: A Unified Path of Environmental Protection and Art
With tightening regulations on VOC emissions both domestically and internationally, water-based UV resins and LED-UV curing solutions are emerging as new trends in snowflake inks. It is predicted that the Chinese UV ink market will exceed 5 billion yuan by 2025, with high-performance and environmentally compatible products driving the growth.
With the widespread adoption of chip-scale point-source curing equipment, snowflake textures are expected to be "printed on-site" in the future. Designers can create customized patterns in real time in front of customers, instantly creating a shimmering, snowflake-like texture on packaging.
The romance of technology lies in its ability to transform the fleeting nature of winter snowflakes into enduring, crystalline art on packaging.
