Tradition and innovative spirit

The Hamburger Containerboard first started papermaking in Germany at Trostberg, more than 100 years ago, originally under the name of the company founder: Rieger. From the production of handmade paperboard and cardboard, development became focused, over the decades and then with the acquisition by the Austrian based W. Hamburger AG (1989), on white testliners. Over the years RiegerLiner has become a brand name in its own right. The successful development and progress in this product segment then led to the construction of the new plant in Spremberg. The PM1 went into operation in 2005.

After the merger of both locations in 2010, Hamburger Containerboard was expanded in 2014 with the Papierfabrik (paper mill) in Gelsenkirchen. Today Hamburger Containerboard is the market leader in the field of coated and uncoated white testliners. The names of the original company founders, Wilhelm Hamburger (Pitten, Austria) and Johann Rieger (Trostberg, Germany), are retained to this day in the names of our companies.

The entrepreneurial vision and outstanding achievements of our company forefathers and the Prinzhorn family set a precedent for the continuous sustainable development of our company for the future, to which we are all bound. Through this we embody both Tradition - our shared experience and common value set - and Innovative Spirit - our capacity to innovate, develop new products and processes, and implement state-of-the-art machinery and systems. We do not see any contradiction here – on the contrary. Only those who are aware of their past and willing to learn from it are able to shape the future.

And this symbiosis of old and new is what defines us: For example, our board machine 1 has been running, on and on, for 95 years (!); the paper machine 1 in Trostberg for 28 years, the paper machine in Gelsenkirchen for 48 years and the PM1 in Spremberg for a mere 15 years. All of this – and much more – constitutes our "fascination for paper"!
