LLDPE metallocene grade
Sorun Belirtisi
Ordinary LLDPE stretch film has insufficient strength, performance leaps after switching to metallocene LLDPE
Neden Analizi
Metallocene LLDPE (mLLDPE) has narrower molecular weight distribution and more uniform branching; strength, toughness and optical properties are significantly better than ordinary LLDPE; but processing viscosity is higher and requires equipment matching
Çözüm
①Choose mLLDPE grades for high-strength needs; ②check equipment power and torque against high viscosity; ③blend with ordinary LLDPE to balance cost; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Temel Çıkarım
mLLDPE is the performance upgrade route for stretch film; the strength leap requires equipment matching as a prerequisite; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
