A synthetic resin woven bag is provided to prevent various contents in the woven bag from being escaped outside by adhering an end of the woven bag through ultrasonic waves, thereby preventing breathing problems of a worker due to PVC(PolyVinyl Chloride) powder. A synthetic resin woven bag contains various contents such as a fertilizer, cement, and a chemical product. The synthetic resin woven bag includes an adhesion unit(16) formed by fusing an end of the woven bag with ultrasonic waves. In particular, when the ultrasonic waves are applied to the end of the woven bag, a PP(Polypropylene) film is melted to be fused and the fused spot is entirely adhered. An upper part of the adhesion unit is sewn by a sewing thread(14). To surround the adhesion unit and the sewing thread, a finishing sheet(12) is heat-fused by a hot melt(18).
