Bobst event focuses on barriers and short run gravure

20 November 2014


The latest trends in new barrier technologies and short run gravure printing were discussed at a recent conference and open house at Bobst's San Giorgio Monferrato site in Italy.

Bobst experts and representatives of leading international companies from throughout the flexible packaging value chain addressed the challenges and opportunities that the latest materials, systems and production tools represent to the growth strategies of printing and converting companies.

Dr Carolin Struller from Bobst Manchester illustrated the company's in-depth research on AlOx clear coating. Bobst Manchester has, and continues to, carry out extensive trials on the process and is researching ways that in the future could enhance their printability and prevent barrier loss during converting.

Kurt Freye and Daniele Cerizzi from Reifenhäuser Kiefel Extrusion and Reifenhäuser Cast Sheet Coating presented the latest developments in blown film and cast extrusion for high barrier applications which reflect the trend for lower pack weights yet with increasing pack performance. This makes 9 to 11 layer films an important trend which has generated several ongoing projects for machines which can produce increasingly sophisticated multi-layer structures using less material.

Paolo Serafin, of Taghleef Industries, presented their Extendo film applications, offering solutions for better recycling.

On short run gravure printing, Janoschka's Stuart Jones spoke about the innovations the company has been working on in rotogravure sleeve systems, as well as on the retail trends for mass customization. Professor Armin Weichmann, from Stuttgart Media University, illustrated the studies that the institute is carrying out on conductive layers, cylinder stability and the feasibility of nickel to replace copper and chromium in engraved cylinders.

The gravure technology update was rounded up by Giovanni Caprioglio from Bobst Italia, who illustrated the comprehensive range of Bobst presses for flexible materials, focusing on the Minimised Waste concept of the Rotomec MW 60/80 model. Later in the day, at the nearby Bobst Italia Technology Center, an 850mm web width MW 80 printed a demo job on a 12 micron PET substrate coated with AlOx.
