The development of Flexo-EB inks to offer more sustainable ways of printing

The continuous pressure of finding more sustainable and profitable ways of printing has recently been pushed forward by the increased interest in finding recyclable packaging solutions from both Governments and brand owners. It is in this line of development that the Flexo-EB inks were created 10 years ago and have evolved in reaching the stability and quality that the flexible packaging market demands. 

Presently, there are three different reliable technologies and five ink suppliers available: Wetflex, Gelflex-EB, and Elex One are the technologies provided by Sun Chemical, Wikoff, Sakata Inks, Siegwerk, and Toyo Inks. 

As a result of Flexo-EB inks, converters are able to create package print that withstands shipping and handling better than traditional inks, providing superior print protection from production to the store shelf. This gives the printers and brand owners the ability to consider strategies that reduce or eliminate laminations in favour of surface print. Whether its gloss or matte, Flexo-EB inks can produce a wide array of eye-catching print designs using multi-coloured palettes as well as various tactile packaging surfaces. 


Key advantages: 

Printing quality

Flexo-EB inks have the highest physical properties and are resistant to scuffs, abrasions, and chemicals. Additionally, Flexo-EB ink creates less dot gain and better colour consistency over longer runs, increasing pigment density in comparison to traditional ink, which allows for the use of less ink, while maintaining colour and quality excellency. 

Reduced costs

The specific characteristics of EB inks, regarding gloss and resistance, makes them the leading choice when it comes to cost reduction by eliminating the lamination process from the manufacturing of packaging. The increased ink brilliance and their resistance to scratch, enables the execution of surface printing, over one substrate, instead of reverse printing and lamination. This application is cost effective for the converters, as one process is avoided and the substrate costs are reduced. 


The sustainability of Flexo-EB ink is among one of its many features. Compared to traditional inks, Gelflex-EB produces an 85% reduction in solvent emissions, which is the lowest reduction of Flexo-EB inks; Wetflex and Elex One both have a solvent emissions reduction of 100% because they are completely solvent free. Additionally, the surface-printed films produced using Flexo-EB are 100% recyclable.
