How is a spout pouch filled and sealed during production?
The manufacturing process for a spout pouch can be executed using either pre-made pouch machinery or continuous form-fill-seal equipment. In standard pre-made operations, automated machinery picks up the pouch, opens the top or spout opening, and injects liquid cleanly. The spout fitment is inserted or pre-welded into the top edge using ultrasonic or thermal heat sealing. Advanced anti-foaming nozzles prevent splashing during rapid liquid injection to maintain seal hygiene. After precise liquid volumetric dispensing, high-torque capping units secure the closure tightly to form a tamper-evident seal before final product packaging and palletizing.
