Valve Bag Tuber Machine

Multi-wall paper tubing machine for making valve bags and open-mouth bags used in the construction, chemical and food industries

Max. speed

450 tubes/min

Tube width

300-750mm

Tube length

410-1650mm

The valve bag tuber machine is capable of producing a wide variety of valve bags, including those with an internal layer of PP/PE film or tubular PE plastic film. These bags are ideal for packaging materials such as cement, multi-layer flour, pet food, dry building mixtures, mortar, tile adhesives, refractory materials, gypsum, starch adhesives, carbon black, PVC paste resin, cellulose, latex powder, and titanium dioxide. The valve bag tuber machine can also be equipped with four-color, six-color, or even eight-color printing machines, offering extensive customization for your packaging needs.

During production, the valve bag tuber machine can be seamlessly integrated with the bottomer machine through an automated conveyor system, all controlled via an easy-to-use control panel. This integration significantly boosts production efficiency and reduces labor costs. Additionally, our valve bag tuber machine can be customized based on your specific requirements, and we can tailor a fully automated valve bag production line to meet your unique production needs.

Advantages

Advanced Digital Control Technology
The tuber machine uses cutting-edge digital control, ensuring minimal cutting errors. No gear changes are required, with cutting length deviations of less than 2mm, ensuring precise production every time.

Stepped-End Cut Design
The machine features a quick diameter change design for the stepped-end cut, preventing paper breakage and knife entanglement. This design increases production output and reduces waste, while the one-click diameter adjustment allows for easy size changes.

Optimized Forming Structure
The machine’s improved forming section effectively controls the internal tightness and external looseness of the three-layer paper, ensuring seamless paper bonding.

Oil-Free Drive System
The machine operates without oil, requiring no lubrication and meeting stringent hygiene standards for pharmaceutical and food-grade environments.

Perforating Design
The perforation system prevents internal paper adhesion caused by lateral glue application, reducing defects at the opening when connecting to the bottomer machine.

Automatic Tension Control
The system automatically manages tension to prevent paper bag damage caused by uneven tension. The newly designed belt traction and tear-off system eliminate surface impressions and tearing, minimizing the risk of damaged bags and customer complaints.

European-Sourced High-Quality Components
Key parts are sourced from Europe and made from alloy steel using high-standard heat treatment processes. This ensures long-term stable and reliable performance for continuous production.
