Ruizhi Machinery Unveils Three New Paper Bag Machines at All in Print China 2026

New High-Speed Paper Bag Machines Debut at All in Print China 2026

The five-day All in Print China 2026 exhibition concluded successfully at the Shanghai New International Expo Centre, with Ruizhi Machinery introducing three new paper bag making machines at Booth N3A213. The new equipment—designated CS350T, CS450T, and RZFD-250AS—emphasize high-speed production, rapid size changeovers, and integrated automation features.

CS350T: High-Speed Production with Rapid Size Changeovers

The CS350T is engineered for high-volume production, achieving speeds of up to 300 bags per minute. A key feature is its one-click automatic size changeover capability, completing transitions in just 15 minutes. The machine incorporates a multi-servo control system, German LENZE motion controller and servo system, and SICK photoelectric tracking technology to maintain stable operation and precise bag formation at elevated speeds.

CS450T: Large-Format Bag Production with Flexible Size Changeovers

The CS450T produces large-format paper bags with handles, supporting a maximum bag bottom width of 260 mm and speeds of up to 150 bags per minute. Its 25-minute size changeover process enables manufacturers to manage multiple specifications and small-batch orders while minimizing manual adjustments and production downtime.

RZFD-250AS: Integrated Visual Inspection, Automatic Stacking, and Bundling

The RZFD-250AS integrates paper bag manufacturing with visual inspection, automatic stacking, and bundling functions. An inspection system identifies and rejects defective bags, while passing units are automatically stacked and bundled, reducing manual handling and improving downstream efficiency.

Advancing Paper Bag Manufacturing Through Innovation

According to the company, the three machines collectively address diverse production requirements. The CS350T combines high-speed output with quick size changeovers to enhance mass production efficiency. The CS450T offers large-format bag manufacturing and rapid size changeovers to accommodate varied orders. The RZFD-250AS reduces manual labor in downstream operations through automated defect rejection, stacking, and bundling. The company emphasized that these machines support material compatibility, operational stability, and consistent bag quality.

Industry Engagement and Future Commitment

The exhibition provided a platform for Ruizhi Machinery to exchange insights with industry professionals on production efficiency, automation, and evolving packaging needs. While the event has concluded, Ruizhi Machinery stated its commitment to technological innovation and continued optimization of machine performance and automation technologies to support the sustainable development of the packaging industry.

Practical Implications and Verification

For manufacturers, the new machines offer potential improvements in production throughput and flexibility. The CS350T's 300 bags-per-minute capacity and 15-minute changeover time may benefit high-volume operations, while the CS450T's 25-minute changeover supports small-batch customization. The RZFD-250AS's integrated inspection system could reduce labor costs and improve quality control.
