Both InverFreez and InverTop provide the customer with cost-effective alternatives to virgin board and each has allowed Caraustar to enter into and effectively compete in two markets dominated by virgin paperboard.
Savings with Fourdrinier Technology
Premier Boxboard Limited (PBL), Caraustar's joint venture with Inland Paperboard, also utilizes the Fourdrinier process to manufacture a strong, lightweight, three-ply gypsum facing paper for the wallboard industry.
PBL, with a capacity exceeding 280 thousand tons per year, is the largest of four mills in the U.S. capable of producing gypsum facing paper using the Fourdrinier technology. Used in the production of gypsum wallboard paper for residential and commercial construction, PBL's lightweight paper provides wallboard manufacturers with significant savings in energy, freight and improved production efficiency.
PBL's production of lightweight gypsum facing paper is allowing Caraustar to expand its share in the gypsum wallboard paper market. PBL increased its gypsum facing paper production by 44 percent in 2002 and is expected to double its facings production in 2003.
