How to Troubleshoot Common Issues with Liquid Sachet Packing Machines

Liquid pouch packaging machines are ubiquitous in the food, pharmaceutical and cosmetic industries and are a key component in the efficient and reliable production of small liquid products. Just like any machine, these machines can experience problems, leading to delays, waste, and frustration.

To help you maximize packaging efficiency and avoid costly downtime, we’ve compiled this guide that addresses the most common faults in liquid pouch packaging machines and its simple troubleshooting tips.

1. Leakage or improper sealing

Cause: Seal heating element temperature is too low or seal pressure is insufficient.

Solution: Check and adjust the seal temperature setting. Check seal pressure and increase pressure if necessary.

2. The pouch is not filled or not filled enough

Cause: feed pump failure, blocked filter or insufficient liquid supply.

Solution: Check feed pump and calibrate. Clean or replace the filter. Ensure that the liquid supply is adequate and unobstructed.

3. Bag size is not correct

Cause: improper setting of molding roller or film tension is too tight.

Solution: readjust the forming roller. Check film tension and adjust as needed.

4. The bag is broken

Reason: poor film quality, sealing temperature is too high or the pouch is under excessive pressure.

Solution: Use high quality film. Adjust seal temperature to ensure proper seal strength. Reduce pressure on small bags during storage or transportation.

5. The machine cannot start

Cause: Power failure, blown fuse, or disconnected main switch.

Solution: Check the power connection. Replace the blown fuse. Check and switch on the main switch.

6. Noise or vibration

Cause: The machine is not properly aligned or the parts are loose.

Solution: Check the levelness of the machine and make necessary adjustments. Tighten any loose parts.

By following these troubleshooting tips, you can quickly and efficiently solve common problems with liquid pouch packaging machines, ensuring that your production line runs smoothly. By minimizing downtime and maintenance costs, you can increase production, reduce costs, and improve customer satisfaction.
