HP used the Interpack show in Dusseldorf, Germany, to announce a number of new packaging solutions for both corrugated and flexible packaging.
HP has shared more details of its PageWide C500 press, which was announced at Drupa. This is a single pass inkjet press, using water-based inks that’s designed for printing to corrugated boards. It uses a virtual belt to print to 1.3m wide coated and uncoated papers and boards, without requiring further lamination.
Eric Wiesner, general manager, HP PageWide Industrial Division, explained: “This post-print corrugated solution from HP is yet another step toward digital conversion of traditional printing, offering savings in waste and setup time and improved supply chain efficiencies, in addition to high-quality color graphics, easy customization, and unique versioning capabilities.”
It will be complemented with a fully integrated stack-to-stack workflow complete with an in-line overprint varnish solution. It’s due to begin beta testing at the end of the year and should be commercially available sometime in 2018. HP claims that it will be able to produce 25 million square meters of boards annually.
HP already has a fairly comprehensive portfolio of presses for corrugated printing, including the single pass T1100S and T400S plus the flatbed Scitex 17000.
There’s a new option for producing on-demand pouches, Indigo Pack Ready Lamination, that is designed for use with the Indigo 20000, 8000 and WS6800 presses. It’s a two-piece solution that includes the HP Indigo Pack Ready Laminator and Pack Ready Film. The laminator provides strong laminate bond strength without wasting time on curing, while the Pack Ready Film contains a heat active polymer layer that mechanically interlocks with HP’s Indigo ElectroInk once sufficient heat and pressure are applied.
It was shown at last year’s Drupa as a concept with customers asking for it to be developed fully. HP demonstrated at Interpack the new Pack Ready Laminator for the Indigo 20000, which should ship by the end of this year. HP says that the films comply with most global food packaging safety regulations. There are Pack Ready food contact-grade films now available from suppliers such as Polyplex and Polifilm.
There’s also a post-print coating solution, Pack Ready Coating, that’s been available since last November. This now supports microwavable clear retort pouches.
In addition, HP has added to the range of substrates that can be used with its 762mm wide Indigo 20000, which can now handle aluminum and polyethylene. There are also new substrates for the B2 Indigo 30000, which prints to sheetfed folding carton, and can now print to metallic and synthetic substrates.
