Çözüm
Air ring airflow and air temperature stable; frost line height fixed and monitored; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability; Change only one variable at a time and record parameter changes, to facilitate locating effective measures.
Temel Çıkarım
Frost line stability is a sign of LLDPE film consistency; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future.
