💡 What causes uneven shrinking on plastic film when using a heat seal tunnel machine?
The main issue usually stems from incorrect airflow settings or mismatched film thickness.
- Adjust the blower fan speed so hot air circulates evenly across the wrapper
- Match the shrink film gauge to the weight of your packaged items
- Verify the conveyor belt moves at a steady rate without sudden stops
- Keep the sealing blade clean to maintain consistent thermal contact
