The fully automatic premade bag packing machine is a high-speed, eight-head rotary system engineered for preformed expansion/stand-up pouches. Designed to run continuously on demanding beverage and food lines, it integrates pouch handling, precise dosing, and stable heat sealing into one compact platform. With servo-based volume control, intelligent “no bag, no fill/no seal” logic, and CIP-ready hygienic architecture, the machine helps manufacturers improve output consistency, reduce leakage risk, and shorten changeover time when switching between SKUs or pouch formats.
Product Introduction
This rotary premade pouch filling and sealing machine uses an eight-station/multi-head configuration to complete bag feeding, opening, filling, and sealing in a synchronized cycle. It is optimized for fixed-shape preformed pouches with standardized openings and is particularly suitable for liquid and semi-liquid products that require repeatable filling accuracy and dependable seal integrity. Key product-contact areas employ hygienic materials, while the filling system supports external CIP connections to streamline sanitation and reduce downtime between batches.
Product Features
High-speed eight-head rotary performance: The rotary architecture delivers stable high-throughput production, reaching up to 7,000 bags/hour (based on 100 ml water medium reference), supporting capacity expansion without excessive floor-space demand.
Servo-driven quantitative adjustment: Servo control enables fast, digital volume setting with repeatable accuracy. Operators can perform capacity changeovers quickly and reliably, improving efficiency for multi-product or multi-volume production schedules.
Precision dosing for consistent quality: The filling system is designed for accuracy of ≤ ±1 ml (water medium). This helps maintain consistent net content, reduces overfill, and supports tighter process control in high-volume manufacturing.
Independent sealing temperature control: Single-point temperature regulation for sealing improves stability and supports consistent seal formation. Integrated interlocks such as “no bag, no fill” and “no bag, no seal” reduce material waste and prevent contamination events.
Low sealing failure and anti-leak design concept: With stable heat control and process logic, the sealing failure rate is designed to be low (about 3‰ under specified conditions), helping protect downstream packing, secondary packaging, and logistics performance.
Hygienic build with CIP readiness: Key product-contact components (such as filling valve/nozzle) use 316-grade material, and the system supports external CIP pipeline connection. This design supports frequent cleaning cycles, shorter sanitation time, and better compliance with hygienic production requirements.
Per-head pneumatic control for process stability: Each head’s sealing cylinder pressure can be adjusted independently, allowing fine tuning for different pouch materials and thicknesses. Digital pressure visualization improves setup efficiency and repeatability across shifts.
Wide pouch compatibility with quick changeover: Suitable for standardized preformed pouches that are flat, non-sticking, and deformation-free. The machine supports rapid switching between compatible bag types, improving responsiveness for short runs and OEM/ODM co-packing needs.
Industrial-grade automation and reliability: PLC/HMI control, proven pneumatics, and robust bearings are selected to support long-term stable operation, reducing unplanned downtime and simplifying operator management.
