Fully automatic square bottom paper bag machine is designed for the production of paper bags with twisted handles. It is suitable for mass production of shopping bags in industries such as food and clothing. The one-line process consists of twisted handles making from paper rolls and twisted rope, delivery of handles to paste unit, pre-cutting of paper on position of rope, patch position gluing, handle pasting, and paper bag making.
The paper bag making process consists of side gluing, tube forming, cutting, creasing, bottom gluing, bottom forming and bag delivery. This machine adopts German imported high-speed motion controller (CPU), which controls the operation of servo through high-speed bus to ensure stable movement and smooth motion curve. It is the automatic square bottom paper bag equipment with handles inline preferred by the majority of printing and packaging manufacturers.
A: The machine can produce up to 150 bags per minute without handles and up to 120 bags per minute when producing bags with handles inline.
A: It utilizes a German original LENZE PC control system integrated with optical fiber and a SCHNEIDER touch screen interface for stable and high-speed operation.
A: It is ideal for mass production of shopping bags used in the food, clothing, and retail industries where high-quality square bottom bags are required.
A: Yes, it features a fully automatic one-line process including handle making, patch gluing, handle pasting, and bag forming without manual intervention.
A: The machine supports paper roll widths from 630mm to 1370mm with a maximum diameter of 1300mm and paper thickness ranging from 80-150g/㎡.
A: It uses a German original SICK photoelectric eye correction system to track printing marks accurately, ensuring every bag is cut and formed correctly.
