Hot Melt Troubleshooting - Application Issues

When a packaging line starts to struggle with weak bonds, popped flaps or inconsistent glue patterns, the root cause is often simple: insufficient adhesive being applied. But understanding why it’s happening—and how to fix it quickly—can save significant downtime and frustration.

From blocked nozzles and clogged filters to low temperatures, low pressure, tank melt levels or pump cavitation, even small deviations in your hot melt system can starve the bead and compromise performance. The good news? Most of these issues can be diagnosed and corrected rapidly once you know what to look for.

That’s why we’ve created a practical Hints & Tips Sheet dedicated to solving application-related hot melt problems. It breaks down the key causes, shows you how to identify them on the line, and gives clear corrective actions you can implement straight away.
