HEIDELBERG, GERMANY—  Heidelberg has increased factory working hours by around 14% as it gears up for a busy H2 big post-Drupa order backlog. CEO Jürgen Otto said the group’s factories were running flat out. Otto noted that the forecast sales volume for new machines “has already been almost entirely met with orders and our production operations are running at full capacity”. Orders at its Packaging wing were up 9.7% to €675m at the half year, around 53% of total order volumes. In packaging, the replacement of plastics with paper-based materials is viewed as a key growth opportunity, along with growing demand for premium packaging products “providing a tailwind to conventional printing technologies”. The biggest growth in orders received came from the Asia Pacific region.
