An absorptive laminated sheet material having improved, moisture-resistant, pressure bonded spots for locking the lamination layers together. During fabrication of the laminated product, a thermoplastic low-viscosity wax-like substance, such as melted wax or paraffin, hot melt plastic or the like, is applied in minute amounts onto juncture lines of pressure bonded spots formed in the pads. The thermoplastic material penetrates the layers of the laminated product so that, on cooling, it forms a "wax rivet" at each bonded spot, thus providing added strength for the juncture lines and rendering the layers impervious to absorbed liquid at the points of application.
