Based on advanced German and Formosan technology, we researched and designed practical model by ourselves. Since its great performance and low energy consumption, it is widely used for manufacturing compound bags, centre joint coated bags, light bags with big size, container bags, color bar waterproof bags and other relative fields. Machines of this type have many traits such as convenience in operation & maintenance, scientific structure, less quick-wear parts, lower energy consumption as well as smooth and flat woven bags etc.
