Packaging giant Krones has enjoyed rising sales and earnings for the first quarter of the year.

The German group saw post-tax earnings for the three-month period leap 9.8% to EUR19.1m (US$24.1m) on the back of an 11.6% jump in sales to EUR451.6m.

Krones pointed to the improving German economy for the buoyant performance and said an increased number of orders should mean continued growth during the rest of the year.

"Krones is targeting not only sales growth of between 5% and 10%, but primarily a sustained increase in earnings," the company said when announcing its results late last week.
