Flint Group has launched a new packaging ink set for paper cup applications, PremoCup, which it says delivers wet and dry rub resistance without affecting print quality.
The inks use the company’s building block formulating technology, and comes with an extremely wide operating window that substantially reduces the variation in print quality caused by inconsistent coating weights commonly observed with long standing technology.
The trend for paper cup printers is for increased print fidelity and complex designs to enhance appeal. High fidelity graphics are pushing the limits of conventional ink systems.
Tony Parrish, Flint Group account executive, said, ‘While printing PremoCup at a key customer facility, it was clear that PremoCup printed cleaner allowing the customer to only shut down for routine cleaning at shift changes rather than multiple times during the shift – increasing their overall productivity and resulting in high quality graphics.
‘Our customer appreciates the fact that they can substantially reduce costs associated with conventional pH adjusters to maintain viscosity; the press operators were happy to focus on other tasks rather than constantly maintaining the press due to quality issues.’
PremoCup is designed to deliver wet and dry rub resistance on a variety of polycoated paperboard and paperboard substrates, has a wide operating window under normal environmental conditions, and maintains a consistent viscosity while on press.
Lloyd Woodrum, product manager, Paper & Board North America, said, ‘The viscosity stability and extremely wide operating window associated with PremoCup is essential to reducing the colour and density variation common with traditional inks that require frequent amine adjustments to maintain viscosity.’
The inks can be prepared to match accepted colour standards as a finished ink, or supplied as PremoNova dispersions and extenders for use in an ink dispensing system.
