Flexo started off as a generally low quality printing process for low quality grades, eg, corrugated boxes. Nowadays, modern flexo is capable of extremely high quality, up to and including coated packaging grades. The potential problem in Europe stems from the fact that flexo printed newspaper cannot be deinked to a standard that is suitable for recycling. Considering that newspaper is mainly made from 80–100% recycled fiber, it is clear to see the potential pitfalls.
CEPIPRINT and CEPI recently commissioned a study from industry consultants, Jaakko Pöyry, to investigate the impact of flexo printing in Europe. The results are worrying with the UK and Italy suffering the most. The study shows that if flexo printing rises to 40% in the UK and 39% in Italy, all old newspapers (ONP) and old magazines (OMG) in those two countries would become unsuitable for deinking. Raw materials for newsprint production would be in short supply, which in turn, would push up the price of both raw material and newsprint. But it is not all bad news, Centre Technique du Papier (CTP) in Grenoble, France, is working hard to find a solution to the deinkability of flexo printed fibers. Many companies already support the project, including CEPIPRINT, and a number of papermakers, printers and chemical manufacturers.
