The 8-Station Fully Automatic Pre-made Bag Packaging Machine is a rotary, high-efficiency solution designed for reliable filling and sealing of preformed pouches in continuous industrial production. Built to handle multiple pouch styles—including flat pouches, stand-up pouches, zipper pouches, and M-type bags—this system helps manufacturers standardize packaging quality while increasing output and reducing labor dependence. With stable pneumatic execution, servo-controlled motion, and an integrated weighing and dosing unit, it delivers repeatable bag handling, accurate portioning, and consistent sealing performance across a wide range of products and film structures. It is an ideal choice for operations that require fast changeover capability, strong format adaptability, and dependable long-run stability.
Product Introduction
This rotary pre-made bag packaging platform features an 8-station workflow that automates the core steps of pouch packaging: bag feeding, bag opening, product filling, and heat sealing. The machine is engineered to run common laminated structures such as single-layer PE, PE composite films, paper films, and other multi-layer composites, supporting both protective barrier needs and premium retail presentation. A matched weighing module covers small to mid-range dosing requirements and is suited for granular, particulate, and portioned products that require accurate fill weights. Through a robust combination of electrical control, pneumatic components, and servo drive, the machine is designed to maintain stable rhythm and minimize unplanned stops in demanding production environments.
Product Features
One Machine for Multiple Pre-made Bag Formats
The machine supports a broad selection of preformed pouch styles, allowing one platform to cover diverse SKUs without rebuilding the packaging line. Compatible formats include flat bags, stand-up pouches, zipper pouches, and M-type bags. With a maximum bag size of up to 40 cm in length and 26 cm in width, it accommodates many mainstream retail pouch specifications used across food, chemicals, and consumer goods.
8-Station Rotary Structure for High Throughput Stability
The 8 working stations are arranged in a synchronized rotary cycle that keeps each process step aligned and repeatable. This architecture is designed to sustain consistent output, especially in high-volume operations where stable bag pick-up, reliable opening, and smooth transfer between stations are essential to reducing downtime and improving overall equipment effectiveness.
Accurate Weighing and Consistent Feeding
The integrated weighing system supports a dosing range from 10 g to 1500 g with accuracy of ±0.1–1.5 g, enabling dependable portion control for products with strict weight requirements. A 1600 ml bucket capacity combined with step-motor drive helps maintain stable feeding behavior across materials with different flow characteristics, particle sizes, and densities, supporting both efficiency and product consistency.
Industrial-Grade Control and Long-Life Components
To improve reliability and service life, key electrical and automation components are selected from established brands. The machine integrates Omron relays and safety-door components, Schneider buttons and indicators, Chint circuit breakers, Yuyao temperature control, Qichuang PLC control, Kunlun Tongtai HMI touch screen, MeanWell switching power supply, Huichuan servo motor, Xinbao reducer, and AirTac pneumatic cylinders. This configuration supports stable control response, dependable safety performance, and consistent sealing temperature management in long-run production.
Sealing Performance and Material Adaptability
The system is designed for dependable sealing on common composite structures, including paper-plastic laminations and PE-based composites. Stable temperature control and synchronized sealing动作 help reduce sealing defects and support a clean, shelf-ready appearance, improving both product protection and brand presentation.
