Temperature-sensitive fluctuation of BOPP film
Problembeschreibung
When the production temperature fluctuates, the mechanical properties, thickness, and appearance of the film fluctuate simultaneously.
Ursachenanalyse
BOPP is highly sensitive to processing temperature; fluctuations in stretching and heat-setting temperatures directly change the orientation and crystallization state, thereby affecting all properties.; during on-site investigation, verify item by item according to this mechanism to avoid blindly adjusting the machine based only on experience
Lösung
①Install a precision temperature control system across the whole line; ②stabilize the settings of each temperature zone according to the process card; ③monitor the temperature trend and set alarms; ④regularly calibrate thermocouples.; after adjustment, continuously sample and verify the effect, and resume mass production after confirming stability
Wichtigste Erkenntnis
Temperature stability is the foundation of BOPP quality consistency; the return on investment in precision temperature control is directly reflected in the qualification rate.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
