MP extruded film winding wrinkles
ظاهرة المشكلة
MP extruded film shows transverse wrinkles and longitudinal creases after winding
تحليل الأسباب
film tension uneven, fluctuating ±20%; film thickness uneven causing inconsistent stretching of sections; shrinkage anisotropic after cooling
الحل
1) automatic tension control system to stabilize winding tension; 2) improve film thickness uniformity to ±5%; 3) adjust guide roller parallelism <0.05mm/m; 4) fully cool the film to <30°C before winding
الخلاصة الأساسية
film wrinkling is caused by tension fluctuation and thickness unevenness; automatic tension control and homogenization are key
