The invention discloses a paper-plastic composite woven bag and a production process thereof. The process includes the steps of firstly, coating one face of kraft paper with a polyethylene material, and coating the polyethylene material layer with a high-resistance material; secondly, selecting any mode as follows: the first mode of connecting the high-resistance material layer with the outer surface of a bag body through extrusion casting, compositing and hot sealing to form a cylinder bag, and the second mode of flat distributing the bag body on the high-resistance material layer after cutting the bag body and connecting the bag body with the high-resistance material layer through extrusion casting, compositing and hot sealing to form a composite; thirdly, when the first mode is adopted, sewing a bag sewing thread at the bag opening of the cylinder bag and attaching paper-plastic adhesive tape to the two faces of the bag sewing thread, when the second mode is adopted, connecting middle seams through hot sealing to form the cylinder bag first, sewing the bag sewing thread and attaching paper-plastic adhesive tape to the two faces of the bag sewing thread. Objects packaged in the bag can be effectively prevented from oxidization and caking and can be stored for a long time, and meanwhile the quality and storage time of the paper-plastic composite woven bag are remarkably improved and prolonged.
