Jun 17, 2010. /Lesprom Network/. M-real increases carbonless paper prices by 8-10% by mid July 2010, the company said in a statement received by Lesprom Network. Current sales prices of carbonless paper, despite an already realised increase in April, are not sufficient and do not cover the steadily rising cost for pulp and logistics, the company said. M-real is Europe’s leading primary fibre paperboard producer and a major paper supplier.
