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.

In order to exclude such risks, the plastic packing includes electrically conductive polymers. These polymers may be applied as paint to the outside of the plastic packing.

Abstract: The present invention relates to a packaging unit designed to absorb and/or adsorb liquid that is being transported or was spilled or was released. The packaging unit has at least one sealing multi-layer comprising a first water soluble film and an absorbent/adsorbent material. When the liquid contacts the water soluble film, the liquid passes through the water-soluble film. When the liquid contacts the absorbent/adsorbent material, the absorbent/adsorbent material immobilizes the liquid material. This immobilization prevents the liquid from escaping from the packaging container.
