LLDPE film wrinkling
ظاهرة المشكلة
LLDPE film wrinkles during winding
تحليل الأسباب
Uneven thickness causes uneven tension distribution; when troubleshooting on site, verify item by item according to this mechanism to avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
الحل
Solve thickness uniformity first; optimize winding tension; spreader roll; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record parameter changes to facilitate locating effective measures
الخلاصة الأساسية
The root of wrinkling lies in thickness uniformity; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
