LLDPE film environmental airflow isolation
Problem Phenomenon
Bubble shaking intensifies when workshop airflow changes.
Cause Analysis
The LLDPE bubble has weak disturbance resistance; door/window airflow and air conditioning wind directly interfere with bubble stability.; During on-site troubleshooting, verify item by item according to this mechanism, avoiding blindly adjusting the machine based only on experience.
Solution
①Add a wind shielding enclosure around the bubble; ②adjust the workshop airflow organization; ③close doors and windows with direct blowing; ④monitor ambient wind speed.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability.
Key Takeaway
Environmental isolation is a low-cost high-return stability measure; LLDPE lines especially need it.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence.
