SubscribeZeller+Gmelin is working on the development of a low migration ink series for packaging applications, building on experience gained producing low migration inks for direct container printing.
Print trials have shown that a migration limit of <10 ppb can be achieved.
Other new products include Interact, a comprehensive range of special effect printing inks introduced by Intercolor, a member of the Zeller-Gmelin Group. The range includes visual effects such as pearlescent inks, bright metallic effects and fluorescent inks through to functional systems with tactile and texture lacquers, fragrance coatings and a range of inks which react to light or temperature. The Interact range is available in March/April this year for flexo and screen processes and runs on standard printing presses without the need for modification. The products will be supplied press-ready.
Zeller+Gmelin has also developed a solvent free UV matt lacquer for flexo application using chamber-type doctor blades. Apart from a good adhesion on different substrates, it provides good slip properties, is embossable and thermo-transfer printable, says Z&G. Due to its odour reduced and ITX free formulation, it is applicable for food packaging applications.
Since February last year, Zeller+Gmelin has implemented a program to make all newly formulated UV inks ITX free, including all UV Flexo-, Offset-, Letterpress- and Screen-Ink Series, and the company reports all inks show a high color intensity, low odour and a good adhesion on various substrates.
