The fully automatic premade bag packing machine is a high-speed, eight-head rotary solution designed for expansion (stand-up) preformed pouches. Built for consistent dosing, reliable sealing, and fast format changeovers, it supports demanding beverage and food filling lines while maintaining hygienic standards and stable output.
Product Advantages
High-speed eight-head rotary operation: Delivers stable production up to 7,000 bags/hour (based on 100 ml water medium), helping increase throughput with a compact footprint.
Servo-driven volume adjustment: Servo quantitative control enables fast, digital capacity changeovers with simple operation and repeatable accuracy.
Excellent sealing performance: Independent single-point sealing temperature control supports “no bag, no fill” and “no bag, no seal” logic, with a low sealing failure rate (about 3‰) and leakage performance designed for high-efficiency lines.
Precision filling: Designed to achieve filling accuracy ≤ ±1 ml (water medium), supporting consistent product weight/volume control and improved quality stability.
Hygienic design and CIP readiness: 316-grade material is used at key product-contact points such as the filling valve/nozzle; the system supports external CIP connections for efficient cleaning and reduced downtime.
Independent pneumatic control per head: Each head sealing cylinder pressure can be adjusted independently, with digital pressure visualization for intuitive setup and process stability.
Wide pouch compatibility and fast changeover: Suitable for fixed-shape preformed bags with standardized openings; supports quick switching between bag types to fit multi-SKU production.
Robust industrial configuration: Core components are selected for durability and production stability, including quality bearings, proven pneumatics, and PLC/HMI control for reliable automation.

Application Fields
Food & beverage pouch filling: Suitable for high-speed filling and sealing of liquid and semi-liquid products in preformed expansion/stand-up bags, especially where stable dosing and low leakage sealing are required.
Dairy and protein beverages (process-dependent): Designed for hygienic operation with CIP compatibility, supporting frequent cleaning cycles and multi-product switching.
Functional drinks and flavored beverages: Servo-controlled volume adjustment enables fast capacity changes for multi-SKU production and consistent fill control.
Condiments and sauces (viscosity-dependent): Supports accurate quantitative filling for products requiring tight tolerance control and reliable sealing integrity.
OEM/ODM co-packing lines: Ideal for factories needing rapid format changeover, stable output, and automated control for contract manufacturing environments.
