This specialized machine is designed for manufacturing shopping bags, specifically block bottom bags, featuring either twisted rope handles or flat belt handles made from paper. It can utilize either paper rolls or printed paper rolls as its material input. The entire operation of the machine is overseen by a computer central control system with a touch screen interface and servo motor for precise cut-off length control. This machine is capable of producing paper bags in various sizes and can seamlessly attach paper handles inline, eliminating the need for manual intervention. The process includes automatic paper feeding from the roll, tube formation, cut-off, bottom formation, bottom gluing, bag formation, and final bag output. All these steps are executed in a continuous line, making it an efficient solution for the production of twist and flat handle square bottom paper bags. It represents the pinnacle of technology both domestically and internationally.
