Sunhope developed the FSB650 full-servo high speed flat & satchel paper bag machine using German technology for reference. The machine is suitable for paper roll, printed roll paper such as kraft paper, shiny paper, and coated paper, and is used to carry out perforating, side gluing, folding, tube forming, separating, bottom folding and gluing, and final product collection in one continuous process. According to the customer's requirements, we can also add the servo pre-creasing device. This function makes sealing the bag more convenient and efficient, and the machine itself is easy to operate, making it ideal for producing a variety of paper bags, bread bags and grocery bags.
