Center Seam Bag

Product Structure

The Three-Paper-One-Film Center-Seam Paper Bag Gluing Machine is designed for continuous production of high-quality valve bags. The production process integrates automatic material feeding, multi-layer positioning, gluing, tube forming, reinforcement, die-cutting, counting, and stacking into a single automated system. Powered by a PLC touchscreen and high-precision servo control, the machine delivers stable performance, excellent bag consistency, and high production efficiency.
