Abnormal Coefficient of Friction of LDPE Film
Sorun Belirtisi
If the film roll COF is too high, machine running is not smooth; if too low, stacks slip and collapse.
Neden Analizi
The blooming amount of slip agent (erucamide type) is affected by addition amount, film thickness and storage time; insufficient blooming gives high COF, excessive blooming gives too low COF and affects lamination.
Çözüm
①Adjust slip agent addition amount by application; ②control film thickness and storage aging; ③COF online/offline testing; ④select low-blooming systems for lamination applications.
Temel Çıkarım
COF relies on refined management of slip agent.
