The spout pouch packing machine has emerged as a game-changer in packaging industries requiring precise liquid handling. Combining speed with hygienic design, these machines excel at filling viscous products like beverages, sauces, and detergents into resealable pouches.

Operational Breakdown

1. Pouch Feeding System

   • Robotic arms pick pre-formed pouches from magazines, positioning them under filling nozzles.

   • Vision systems verify pouch orientation to prevent misalignment.

     
     

2. Filling Mechanism

   • Servo-driven pumps ensure ±0.5% dosing accuracy for liquids ranging from 50ml to 5L.

   • Dual filling modes: Volumetric for thin liquids, piston-based for viscous products like shampoo.

     
     

3. Spout Attachment

   • Heat-sealing jaws apply 150-200°C to bond spouts to pouch films (PE/PP/PET).

   • Leak-testing stations use compressed air to detect faulty seals at 0.3 MPa pressure.

     
     

4. Secondary Packaging

   • Finished pouches are automatically counted and boxed at rates up to 60 pouches/minute.

     
     

     Industry Applications

     • Dairy: Milk pouch packaging with 7-day freshness preservation

     • Automotive: Engine oil pouches with anti-counterfeit spouts

     • Cosmetics: Airless designs for serums

       
       

     Conclusion
     By reducing material waste by 40% compared to rigid containers, spout pouch machines align with sustainable manufacturing trends while ensuring product integrity.
