5. MACHINE FEATURES

This machine is designed to produce paper bags from rolls of natural-colored or printed paper, such as kraft paper and food-grade paper, completing the entire bag-making process in a single operation. It features automatic center-line gluing, printing, and bag-forming tracking. The process includes unwinding the roll, cutting to fixed length, bottom creasing, bottom folding, bottom gluing, bag bottom forming, and final product organization—all completed seamlessly in one cycle.

This machine offers easier operation, higher efficiency, and greater stability, making it an ideal eco-friendly paper bag manufacturing solution for producing various types of paper bags, including snack food bags, bread bags, dried fruit bags, and more.

The features of machinne as follows:

1. Specially designed structure significantly expands the machine’s bag-making range, enabling the production of large-sized handle paper bags to meet diverse customer requirements.

2. The electronic control system utilizes imported original components from Japan, ensuring stable and high-speed equipment operation.

3. Material loading is handled by an automatic hydraulic lifting system, while the unwinding unit is equipped with an automatic tension control system.

4. The unwinding section adopts advanced web guiding (edge correction) technology, effectively reducing material alignment time.

5. Equipped with a servo motor control system to achieve precise and efficient operation. 6. Delivers higher production efficiency while ensuring long-term stable performance.
