LLDPE film corona treatment
Sorun Belirtisi
Insufficient print adhesion, low dyne value.
Neden Analizi
LLDPE surface energy treatment window differs from LDPE; fast slip agent migration accelerates treatment effect decay.; During on-site troubleshooting, verify item by item according to this mechanism, avoiding blindly adjusting the machine based only on experience.
Çözüm
①Optimize corona power and speed matching; ②control slip agent dosage; ③re-test dyne value before printing; ④shorten the interval from treatment to printing.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability.
Temel Çıkarım
LLDPE surface treatment requires parameter adjustment targeting material characteristics; aging management is equally important.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence.
