When examining the question of whether corona treatment is necessary for UV ink printing on PE (polyethylene) film, it is crucial to comprehend the unique characteristics of UV ink, PE film, and corona treatment, as well as their interrelationships.

 UV ink for flexo printing possesses a range of notable characteristics that have contributed to its widespread adoption in the flexographic printing industry. The following are the key features of UV flexo ink:

With the rise of environmental awareness and advancements in technology, UV flexo ink, as an emerging green printing material, is gradually becoming the new favorite in the printing industry. 

Environmental protection is an inevitable topic in the printing industry. With advancements in ink technology, UV-LED inks, as a new eco-friendly printing material, are gradually taking a prominent position in the printing sector. UV-LED inks, with their unique environmental friendliness, high efficiency, 

After two and a half years of relentless efforts by the R&D team at StarColor, this solvent-free UV ink finally emerged. Embodying all the merits of UV ink, including fast curing, high adhesion, vibrant colors, and the absence of organic compound emissions, it mirrors the environmental friendliness of water-based ink.

In the printing industry, UV curable inks have occupied a prominent position due to their unique curing mechanism and superior properties such as instant curing, zero volatile organic compounds (VOCs) emission, vivid colors, and exceptional abrasion and water resistance. However, with the heightened environmental awareness and tightening of regulations,

UV Ink is gaining increasing popularity in the printing industry due to its numerous advantages in environmental protection, cost, and technology. 

UV ink, or ultraviolet-curable ink, is an ink that rapidly cures upon exposure to ultraviolet light. With its unique curing method and exceptional properties, UV ink has gained widespread application in the printing industry

LED curing technology, a modern approach to ink curing, has revolutionized the printing and coating industries. This technology, which employs LED light sources to initiate the curing process of UV inks, offers significant advantages over traditional UV curing methods. As LED curing technology continues to evolve and upgrade, it is crucial to understand its implications for UV ink performance.

UV ink is a special type of printing ink that is cured and hardened by ultraviolet (UV) irradiation during the printing process. UV ink contains a chemical called a photoinitiator, which triggers a chemical reaction when exposed to ultraviolet light, causing the ink to quickly solidify. This UV curing property makes UV ink widely used in the printing industry.
