In formulating UV inks for shrink applications, Bob Waddington, general manager for UVitec, points out that the resins and photoinitiators must be selected to “allow for the shrink of the film and not crack off the substrate, as well as function in a relatively ‘cooler’ environment [no distortion].” UVitec has recently introduced a new UV shrink sleeve ink system that has improved resistance to cracking and delamination.
