The use of UV Flexo ink on flexible packaging is becoming increasingly popular for flexographic printers because of it ever-increasing improvements in print quality. UV Flexo ink’s ability to cure instantly and be converted in-line in addition to its high gloss, high quality appearance make it attractive to flexographic printers.
Variables such as resin selection, amount of ink applied, substrate absorbency, UV curing conditions and print speed can all can propagate episodes of erratic adhesion on difficult substrates. Printers have turned to primed or coated substrates to perform adhesion promotion. Nevertheless, these additional coatings are not always successful and increase the cost of the substrate.
Tune into the webinar as Enercon’s Rory Wolf, reviews a recent study conducted with Cytec Industries that evaluates the different formulations of surface modification techniques and oligomer types, and their impact on adhesion to unprimed flexible polymer-based surfaces.
