4 Core Advantages of the Back Seal Liquid Packaging Machine
1. High-Speed Double-Head Packaging
The SYB-IIISD uses a double-head packaging structure to improve production efficiency. With production capacity up to 134 bags/min, the machine supports high-throughput pouch packaging for liquid and semi-fluid products.
2. PLC Control and HMI Touchscreen Operation
The machine uses PLC control and an HMI touchscreen for filling volume adjustment, speed setting, production monitoring, alarm display, and recipe management. This makes operation easier and supports flexible switching between different products.
3. UV Film Sterilization and CIP Cleaning
Strong UV sterilization treats the PE film before filling, while the CIP-ready liquid circuit supports automatic circulation cleaning. These features help improve packaging hygiene and reduce manual cleaning work between production batches.
4. Stable Servo and Pneumatic Hybrid Drive
The transmission system combines servo motor control with pneumatic actuation to support stable film feeding, filling, sealing, cutting, and date coding. This structure helps improve reliability, service life, and packaging consistency during continuous production.
Applications

Workflow
First, PE roll film enters the servo film feeding system and passes through UV sterilization. The machine forms the pouch, meters the product, fills through the double-head filling system, completes back sealing, cuts the pouch, prints the date code, and discharges the finished bag automatically.
Operators can adjust packaging speed, filling volume, sealing settings, counting functions, and production parameters through the HMI touchscreen. The machine can work as a standalone packaging unit or be integrated into a complete liquid filling and packing line.
