Sustainable Converting New sustainable glue in corrugated packaging
An innovation from Borregaardmakes it possible to produce corrugated board without adding boron derivatives in the glue
regulatory concerns about borates, as well as improving productivity and quality of the board”. Boron derivatives, classified by the
P
European Chemical Agency as Substances of Very High Concern suspected of damaging fertility and the unborn child, are used in the glue to make corrugated boards. The starch glue suppliers and the corrugated board industry has yet not been able to replace these hazardous compounds. Over a period of over two years the
Norwegian corrugated board producer Glomma Papp has, together with Borregaard and the Exilva innovation, extensively tested, produced and developed corrugated board solutions with no added boron. “We started to technically qualify a
boron free solution. Then we have used Exilva as a productivity enhancer. Doing
roject director for Exilva Per-Ivar Heier at Borregaard says, “This solution is a response to
this, we have an option to step by step reduce the boron compounds in the glue, in a controlled manner. Exilva enables us to run smoother, faster, and with improved quality and speed. Based on around 70 million m2 produced boards with Exilva, we’ve measured production improvements by 14 per cent and reduced warp with 11 per cent”, says corrugator supervisor Jan Berg at Glomma Papp, Norway. Borregaard has innovated a new to the
world Microfibrillated Cellulose technology called Exilva, a completely natural and sustainable wood-based solution. The product has a unique combination of robustness and rheological properties creating a strong network that enables the replacement of boron derivatives in corrugated starch glue systems. Exilva har received funding from the
Bio-Based Industries Joint Undertaking (BBI) under the European Union’s Horizon 2020 research and innovation programme
under grant agreement No 709746. Borregaard has one of the world’s most advanced and sustainable biorefineries. By using natural, sustainable raw materials, Borregaard produces advanced and environmentally friendly biochemicals that can replace oil-based products. Borregaard has 1100 employees in plants and sales offices in 16 countries in Europe, America, Asia and Africa. Health, safety and environment are integrated into Borregaard's business plan. The company aims to show social responsibility. Glomma Papp is a modern and
innovative manufacturer of environmentally friendly corrugated and solid cardboards for the Norwegian and Nordic markets. The company has designed, developed and produced packaging and display solutions since 1931. Glomma Papp has 185 employees and is located in Sarpsborg, Norway.
