The production team needs to reduce airborne and falling powder at the moment of jaw closure without hiding the problem by slowing the whole line unnecessarily.
What the symptom can indicate
Powder can continue falling after auger stop because of product in the tube and airborne fines.
Bag vibration or product impact can throw material upward into the open seal area.
Dust extraction placed incorrectly can disturb the dose or draw film toward the nozzle.
Buyer analysis
Separate tailing from airborne dust
Use high-speed video and clean test film to identify whether contamination is a concentrated late stream or dispersed dust. The two patterns require different corrections.
Coordinate cut-off, settling and jaw closure
Auger stop, gate action, bag support, dust extraction and seal timing should be reviewed as one sequence. A short controlled delay may improve good output more than a faster nominal cycle.
Measure the result with package tests
Track contaminated-seal rate, seal strength and leak failures at the target speed. Visual cleanliness alone is not a complete acceptance criterion.
