Process stability is the key to consistent, reliable printing. Phoseon’s UV LED systems ensure every packaging run receives the same consistent, uniform UV output for repeatable results. Food contact material ink used for UV-cured packaging ensures all materials utilized do not transfer through the package in quantities that would affect the final product safety, odor, or taste. To meet the requirements, Good Manufacturing Practices (GMP) must be used to ensure consistent, stable process control.
UV LED offers excellent through cure due to the long UV-A wavelength, which penetrates through to the media. Phoseon products offer more than 20,000 hours of operation with minimal power drop over time, and have been tested for more than 60,000 hours of lifetime. Additionally, UV LED technology provides a uniform output across the print width which again ensures fully cured product. All of these benefits improve the GMP for manufacturers, with confidence that their products consistently meet requirements.
UV LED food contact material ink is currently available on the market. And with continuing RoHS regulatory challenges for traditional mercury bulbs, it is imperative for the entire UV LED ecosystem to work together, ensuring a smooth stable transition to a food contact material ink future.
