Low Migration UV-Curable Inkjet for Food Packaging
Abstract:UV-curable inks for single pass (web) inkjet printing with low migration potential and suitable for the printing of food packaging have been developed and optimised by mixtures design-of-experiment (DOE) methodologies. The inks have acceptable cure response in air (<250 mJ/cm2) and can deliver levels of contact migratables below 10ppb (0.01mg/Kg(foodstuff)) for each migratable monomer and photoinitiator species measured in this study. The inks can be prepared at viscosities suitable for all common printheads and their performance on commercial presses has been confirmed.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
