LLDPE film dart impact
ظاهرة المشكلة
Dart impact strength fails the standard; heavy-duty packaging applications are limited.
تحليل الأسباب
Dart performance is related to resin comonomer type and orientation state; processing overheating degradation also loses toughness.; During on-site troubleshooting, verify item by item according to this mechanism, avoiding blindly adjusting the machine based only on experience.
الحل
①Select high-impact grades (such as hexene/octene copolymers); ②control processing temperature; ③optimize the orientation process; ④test dart impact batch by batch.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability.
الخلاصة الأساسية
Dart performance mainly depends on resin selection; process protection of molecular weight is an auxiliary means.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence.
