5-40 bags/min Vertical Packing Machine for Liquid Paste Bags

Product introduction of Vertical Packing Machine

The vertical packing machine is an automatic pouch filling and sealing system designed for packaging liquid and semi-liquid products in food-grade flexible bags. It handles pouch sizes from L100–250 mm and W30–160 mm with film thickness between 0.04–0.09 mm. The machine integrates filling, sealing, and conveying processes into one unit, reducing manual operation and improving efficiency. Built with internationally sourced components and strict manufacturing standards, it ensures stable performance, safety compliance, and low failure rates. It is suitable for food manufacturers requiring consistent, hygienic, and automated pouch packaging solutions.

Working Principle

The machine first unwinds roll film and forms it into pouch shapes through a forming system. The product is then measured and filled using a controlled dosing unit. After filling, the pouch is heat-sealed under controlled temperature and pressure. Finished pouches are discharged automatically. The system continuously synchronizes film feeding, filling, and sealing operations. Built-in diagnostic and safety modules monitor key parameters to maintain stable production and reduce operational interruptions.
