Converters who want to avoid the use of photo initiators in energy curing inks can alternatively use electron beam (EB) curing systems to reduce the risk of potential migration problems. Several industrial print trials on Comexi’s central impression EB offset press, called CI8, have shown Siegwerk’s new EB technology offers an excellent print performance, low dot gain, low water dosing with less emulsification and scumming, as well as fast intensity recovery after stops. The new ink technology is suitable for a variety of plastic substrates of the flexible packaging market like coex. OPP, acrylic coated PET, etc.
Due to the excellent print performance of the new EB ink solutions, Siegwerk was invited to supply EB offset inks for Comexi’s last Open House event on December 14 in Girona, Spain, where the company was presenting its new CI8 press to a selected audience.
“We are proud of the acknowledgement of our ink performance by Comexi,” says Stefan Busse, regional director of Application Technology, Flexible Packaging EMEA at Siegwerk. “During the last month, our technical teams in Europe have made any effort in finding ways to help our customers accessing the benefits of offset printing in flexible packaging.”
The new ink technology was developed in accordance with the relevant product safety standards. All ingredients are compliant with the stringent Swiss Ordinance and will also comply with the upcoming new German Ordinance. Own migration tests with trial materials exhibited low migration behavior suitable for food packaging. The new system will add to Siegwerk’s broad range of flexible packaging solutions – while other ink technologies, including UV inks, will continue to have their merits.
