WENZHOU – October 29, 2026 -- Ruizhi Machinery unveiled three paper bag making machines at All in Print China 2026, led by the CS350T, which runs at up to 300 bags per minute and completes size changeovers in 15 minutes. The company presented the CS350T, CS450T and RZFD-250AS at Booth N3A213 during the five-day show at the Shanghai New International Expo Centre.

CS350T reaches 300 bags per minute with one-click changeovers

The CS350T targets high-volume production and supports one-click automatic size changeovers. Its multi-servo control system, German LENZE motion controller and servo system, and SICK photoelectric tracking technology are designed to keep forming precise at high speeds.

CS450T produces large-format handled bags at up to 150 per minute

The CS450T makes large-format paper bags with handles and has a maximum bag bottom width of 260 mm. Size changeovers take 25 minutes, which Ruizhi says helps manufacturers handle multiple specifications and small-batch orders while cutting manual adjustments and downtime.

RZFD-250AS automates inspection, stacking and bundling

The RZFD-250AS combines bag making with visual inspection. Its inspection system identifies and rejects defective bags, and bags that pass are stacked and bundled automatically. The machine is meant to reduce manual handling and improve downstream efficiency.

Ruizhi Machinery said it will continue to optimize machine performance and advance its automation technologies.
