The machine is compatible with unprinted and printed paper rolls, such as kraft paper and food grade packaging paper. It automatically completes the whole process in one continuous operation: paper unwinding, bag body pre piercing, side gluing, tube forming, servo fixed length cutting, bottom creasing and folding, bottom gluing, flat bottom shaping, and finished bag conveying. Fully automatic synchronous operation greatly saves labor and production cost.
Adopting a full servo electric control system, the machine runs stably at high speed with strong power and stable performance. Bag size can be adjusted quickly to shorten model changing time. Equipped with high precision color mark tracking and an automatic deviation correction device, it ensures accurate printing registration, smooth cutting, and a neat bag shape.
The professional pre piercing design keeps the bags well ventilated, effectively preventing bulging and deformation when packing food. The finished bags are firm, beautiful, and high in dimensional accuracy. With a solid body structure, low failure rate, and easy daily maintenance, this machine is a high efficiency and reliable piece of equipment for mass production of large size flat bottom paper bags.
