Mar 19, 2010. /Lesprom Network/. Cham Paper Group plans to increase prices by 10%, effective from April 1, 2010, company said in a statement received by Lesprom Network. Unforeseeable environmental factors such as the earthquake in Chile on 27 February 2010, storm Xynthia over south-western Europe on 28 February 2010 and the very cold winter in Scandinavia have given rise to a shortage of raw materials for the papermaking industry. These environmental factors have had a particularly severe impact on pulp production, virtually bringing it to a standstill and interrupting the logistics chain to Europe and North America, company said. Cham Paper Group is a leading manufacturer of coated speciality papers.
