This invention disclose a process for producing a multi-layer biaxially oriented polypropylene synthetic paper of improved gloss and easy-drying printability by means of 3-layer co-extrusion wherein two different PP resin composites are separately extruded by one primary and two secondary extruders and then co-flowed by a same T-die to form a paper sheet having three layer coating material sheet, and through cooling, bi-axial orientation, surface-coating by prime coating and top coating, winding and calendering to be a synthetic paper depending on the required thickness.
