摘要：The main object of this study was to evaluate the feasibility of using disposable plastic film as a novel wood adhesive in the plywood production, which is done to eliminate formaldehyde release during plywood production and use. The bonding strength of plastic film was determined by testing the strength of three-layer plywood. The results showed plywood bonded with them all met the Chinese National standard (GB/T 17657-1999) for second grade plywood and the highest tensile shear strength was obtained under the pressing conditions of 0.7 MPa, 160 degrees C and 1min mm(-1) with the spread volume of 123.22 g/m(2). In addition, pressing temperature has a notable effect on adhesive penetration and bonded joints forming.
