dc.description.abstract3-ply arecanut leaf sheath boards were made at the laboratory with two veneers of arecanut leaf sheath and one veneer of wood under various combinations and with different glues namely starch glue (cold pressing), animal glue (cold pressing) poly vinyl acetate (Fevicol-Pidilite -cold pressing), Epoxy resin adhesive (Araldite-Ciba Geigy-cold processing) and urea formaldehyde (hot pressing). The boards were tested for their glue shear strength and water resistance in accordance with the IS specifications for tea-chest grade plywood. Areca sheath boards made with UF resin adhesive and wood veneer as core were found to have 50% more wet glue shear strength than the other areca sheath boards. Use of extenders like tamarind seed powder and deoiled sal meal up to 15 % to the UF resin adhesive and the type of wood used were found to have no adverse effect on the glue shear strength of the boards. Though the areca sheath boards satisfied only 50% of the IS requirements for tea chest grade plywood, they were found to have better wet glue shear strength over the locally purchased non-ISI grade tea chest plywood.en_US
