Corrugated board reconceived

Our resources are precious

Recovered paper is a resource that is in great demand around the world and is becoming increasingly important. The level of demand will continue to rise in the years to come. Paper machines which fully exploit all the potential of the recovered paper fibres and can produce high-quality papers economically using fewer resources are in great demand.

Lower CO2 emissions – our commitment

As part of the European Commission’s Roadmap 2050, the paper industry has set itself an ambitious target: to create more added value while at the same time greatly reducing CO2 emissions. With the high-tech Propapier PM 2 machine, we achieved the breakthrough towards 2050: Our approach has been to completely reconceive the notion of corrugated board.

Next Fibre® – Lightweights are reality

The PM2 paper machine produces lightweight containerboard with grammages of between 70 and 130 g/m². PM2 is our response to the high energy and raw material prices that we are seeing. The machine’s high-tech features enable Next Fibre® papers to be produced economically with lower grammages and less use of fibres.

The new corrugated board generation: Slimmer, lighter, same performance

The Next Fibre® high-performance papers are used to manufacture the Next Board® corrugated boards. Thanks to newly developed corrugated board designs, Progroup has successfully managed to achieve higher ECT values as well as improved compressive strength with less use of materials.


The change to the height and width of the flutes and the radiuses of the wave shape in different combinations are the key to optimising performance. Smaller separations and lower heights of the flute make the “free clamping length” shorter, the number of support points increases, which in turn increases the durability.


In addition, this creates a largely flat paper surface which enables a clean, uniform printing result to be achieved. A disruptive ripple effect is effectively prevented.

The new generation of CO2-reduced packaging

Only Next Board® corrugated board is used at our selected production partners throughout Europe to create Next Box® packaging. Companies that use this packaging have persuasive arguments to put to their eco-conscious consumers and point out that they handle precious resources in a sustainable way. Next Box® packaging is noted for offering reliable product protection and a high-quality brand image thanks to very good printing results.


For your packaging assignments, we cooperate with packaging manufacturers in Central Europe which can reliably satisfy your Next Box® requirements from small batch sizes through to a major order. We will be happy to make contact. We look forward to receiving your packaging assignments.

What customers repeatedly want to know – questions and answers

We have put together for you the answers to the most frequently asked questions about a wide range of different topics relating to paper production and safe use with foodstuffs. If your concern or question has not been addressed, we ask you to get in touch with us.

What exactly is Green Hightech and what are the Next Generation Products?

With high levels of investment and consistent development work over many years, Progroup has completely reconceived the notions of corrugated board and corrugated board packaging. The concept of Green Hightech represents a series of Next Generation Products: Next Fibre® containerboard, Next Board® corrugated board and Next Box® packaging which our experienced packaging partners in Central Europe manufacture.

What is the significance of the term carbon footprint in relation to the Next Generation Products?

Carbon footprint or the CO2 assessment of a product is the sum total of all CO2 emissions which occur during the course of its life phases. This assessment allows products to be compared in terms of their effect on the climate and also to be improved by assessing the individual production steps. Progroup has had a product carbon footprint prepared for its Next Board® corrugated board.

For which products has Progroup had a product carbon footprint prepared?

The PM2 paper machine in Eisenhüttenstadt enables fibre-saving production of high-quality containerboards. These Next Fibre® high-performance papers are the basis for lighter and yet strong corrugated boards with a new design, the Next Board® corrugated boards. They have been examined to determine their product-specific carbon footprint.

Which organisation carried out the assessment of the carbon footprint?

Progroup commissioned TÜV Rheinland to carry out this investigation and certification.

How much CO2 can be saved using Next Board®?

The Next Fibre® high-performance papers are used to manufacture the Next Board® corrugated boards. Thanks to newly developed corrugated board designs, Progroup has successfully managed to achieve higher ECT values as well as improved compressive strength with less use of materials. The “Product Carbon Footprint” certification of TÜV Rheinland confirms that Next Board® saves up to 15% CO2 pollution in manufacturing compared to customary grades available on the market.

How much CO2 can be saved during transport using Next Board®?

Next Board® corrugated boards weigh less and are thinner, which means that 16% more m2 can be transported on each truck. However, each truck load is heavier overall due to the additional quantity. As more corrugated board can be transported on each truck, fewer trips are required overall to transport the same amount of corrugated board. 1 in 7 truck journeys can be saved.


Quality papers for the most demanding requirements

Progroup produces high-quality containerboard at two sites in Germany. The containerboard is produced exclusively on the basis of recovered paper. With its “K-Line” and “SLW-Line” product lines, Progroup offers a wide range of paper grades.

Corrugated sheetboard made to measure

At eleven sites in Europe, Progroup produces high-quality corrugated sheetboard. The product range includes a wide selection of profiles of single-wall, double-wall or triple-wall corrugated board. The sheets that are produced on high-tech machines are 100% recyclable.
