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.
