Abstract: A plywood comprising plys of Paulowina wood combined with plys of other hardwoods. The resulting Paulowina based plywood panels are lightweight, approximately 40% lighter than ordinary plywood. This reduction in weight when used for construction of Recreational vehicles (RV's), Campers, Tractor-trailer box sides, Ocean Shipping boxes, Crates, and Steamer trunks will reduce associated fuel consumption by reducing the overall weight of the cargo, and can lower employee related injury. The resulting Paulowina based plywood panels will reduce work place injury (lower back pain, herniated disks, hernia, etc.) resulting in lower healthcare premiums for both employees and employers. The shipping industry that supply cargo shipping boxes also demand that a lightweight construction material be used for goods that are sent by air cargo, land cargo, rail, and sea cargo in order to conserve energy and the Paulowina based plywood panels are well suited for these applications.
