Importance of Troubleshooting
As with any machinery, issues can arise with VFFS machines that require troubleshooting. Keeping your VFFS machine in good working order is crucial to maintain production efficiency, reduce downtime, and ensure the quality of your packaged goods. In this article, we will discuss five easy steps to troubleshoot your VFFS machine effectively.
Step 1: Visual Inspection
Checking for Visible Damage
The first step in troubleshooting your VFFS machine is to conduct a thorough visual inspection. Look for any visible signs of damage or wear on the machine’s components, such as cracks, loose parts, or missing pieces. If you find any issues, address them promptly to avoid further complications.
Ensuring Proper Machine Setup
Another aspect of visual inspection is to ensure that the machine is set up correctly. Double-check the placement of the film roll, alignment of the forming tube, and other essential components. A properly set up VFFS machine can prevent many issues from occurring in the first place.
Step 2: Checking Film Tension
Importance of Proper Film Tension
Film tension is a critical aspect of VFFS machine operation. If the film tension is too loose or too tight, it can cause issues with sealing, bag formation, and product filling. Make sure to check the film tension and adjust it as needed to ensure smooth operation.
Adjusting Film Tension Settings
If the film tension is off, consult the operator’s manual for guidance on adjusting the settings. It’s also essential to use the correct film type for your specific VFFS machine and product.
Step 3: Inspect Sealing Components
Sealing Jaws and Bars
The sealing components of a VFFS machine are critical for creating airtight, secure packages. Inspect the sealing jaws and bars for signs of wear or damage, and replace them if necessary. Clean any debris or buildup that may be present on these components to ensure a proper seal.
Heater Settings
Additionally, verify that the heater settings for the sealing components are correct. Incorrect settings can result in weak or incomplete seals. Consult your operator’s manual or the manufacturer for guidance on proper heater settings.
Step 4: Examine Machine Settings
Confirming Correct Settings
Check the machine settings, such as the fill volume, speed, and sealing time, to ensure they are correct for your specific product and packaging material. Incorrect settings can lead to various issues, including underfilled or overfilled bags and poor seals.
Updating Software or Firmware
Ensure that your VFFS machine is running the most up-to-date software or firmware, as outdated versions may cause performance issues. Consult the manufacturer or your operator’s manual for guidance on updating the software or firmware.
Step 5: Consult the Operator’s Manual
Troubleshooting Guides
Your VFFS machine’s operator’s manual is an invaluable resource for troubleshooting common issues. Refer to the manual’s troubleshooting section for guidance on diagnosing and resolving specific problems. If the issue persists after following the manual’s recommendations, consider contacting the machine’s manufacturer for further assistance.
Maintenance and Cleaning
The operator’s manual should also provide information on the proper maintenance and cleaning procedures for your VFFS machine. Regular maintenance and cleaning can help prevent many issues from arising and ensure the machine’s longevity and reliability.
Conclusion
Troubleshooting your VFFS machine is crucial to maintaining its efficiency, reducing downtime, and ensuring the quality of your packaged products. By following these five easy steps, you can effectively diagnose and resolve issues with your machine. Remember to conduct visual inspections, check film tension, inspect sealing components, examine machine settings, and consult the operator’s manual for guidance. By addressing problems promptly and performing regular maintenance, you can keep your VFFS machine running smoothly and efficiently.

We have a 4 lane vertical sachet machine which worked for 15 years with little issues we sorted out. Now it’s getting stuck with the paper backing up. We readjust it and in a few minutes it’s back to backing up again. Any suggestions would help tremendously as it’s been 3 years now and it’s zero production and bills to pay.
