The production and processing methods of PVC bags are usually high-frequency hot pressing or sewing. The high-frequency hot-pressed PVC bag, that is, the PVC film, is cut into pieces after being cut, and the silk screen of the printing is required, and then the high-frequency machine is used for hot pressing. Generally, the copper mold is required to be ordered and then produced. The hot-pressed PVC bag can be pressed into PVC sleeve bag, PVC welt bag, PVC toothless zipper bag, PVC tote bag, PVC ziplock bag and other styles. After the sewn PVC bag is printed, it can be directly sewn with a sewing machine such as a flat car or a high car. Generally, there are nylon zippers and other accessories.
