Last year at HP Indigo in Israel we got a sneak preview of the company’s HP Indigo Pack Ready set of postprint converting solutions for HP Indigo digital presses. The technology creates a strong bond between HP Indigo digitally printed substrates and Pack Ready laminate film. It cuts lamination cure time to zero so that digital converters can print, laminate and pack on-demand for immediate delivery and reduced environmental impact.
This machine is manufactured and supplied by Karlville, a global leader specialised in providing shrink sleeves, flexible packaging, pounches and the like. Karlville’s business is based on strategic alliances and collaborations with other manufacturers as well as large customers such as Amcor. HP has worked closely with Karlville to design an on-demand laminator that requires no adhesives and is easy to use. HP Indigo Pack Ready can be connected to HP’s cloud based PrintOS.
The HP technology is a thermal laminator that adds a special resin to a laminate recipe. This recipe will be made available to media partners which are specialised in flexible packaging substrates that have numerous layers. The substrate is coated with a primer and then printed with ElectroInk and the printed film is laminated with a laminate film that contains Pack Ready resin. The laminator runs at up to 100 metres per minute across a 300 - 762mm width. A heated drum preheated to 670-170º C.
