This liquid bag packing machine is designed for automatic filling, dosing, and capping of liquid and semi-liquid products such as juice, jelly, paste, and chemical fluids. It supports pouch feeding, quantitative filling, and automatic sealing with stable performance. Constructed with SUS304 stainless steel contact parts and PLC touch screen control, the system ensures consistent operation and hygienic processing. It is suitable for medium-scale liquid packaging lines requiring flexible capacity adjustment and reliable automation.
The liquid bag packing machine is an automated packaging system used for filling and sealing preformed bags with liquid or semi-liquid products. It handles materials such as juice, milk, butter, paste, and chemical liquids within a filling range of 50–500 ml, expandable up to 3L. The machine integrates automatic bag feeding, quantitative filling, air blowing, cap releasing, and locking functions. With SUS304 stainless steel contact structure and PLC control, it ensures stable operation. It is suitable for food, beverage, and chemical manufacturers requiring standardized pouch packaging solutions.
Working Principle
The machine automatically feeds preformed pouches into the working station. It first opens the bag, then performs quantitative liquid filling using a dosing system. After filling, air blowing ensures proper sealing conditions. The system then releases and locks the cap automatically before discharging the finished pouch. PLC control coordinates all steps, while sensors monitor positioning and operation status. The process ensures continuous, automated production with stable filling accuracy and consistent sealing quality.
