Jan 17, 2008. /Lesprom Network/. Caraustar Industries announced that it will increase prices on all paperboard-based converted products by 8%, effective with shipments on and after February 18, 2008. Steven L. Kelchen, vice president, Converted Products Group, stated, "These increases are driven by higher fiber and energy costs, which remain near historic highs and are anticipated to continue to climb. While Caraustar continues to streamline its processes to gain operating and other efficiencies, they alone cannot keep pace with these rising costs." Caraustar, a recycled packaging company, is one of the world's largest integrated manufacturers of converted recycled paperboard. Caraustar serves the four principal recycled boxboard product end-use markets: tubes and cores; folding cartons; gypsum facing paper and specialty paperboard products.
