MP extruded film winding wrinkles
Sorun Belirtisi
MP extruded film shows transverse wrinkles and longitudinal creases after winding
Neden Analizi
film tension uneven, fluctuating ±20%; film thickness uneven causing inconsistent stretching of sections; shrinkage anisotropic after cooling
Çözüm
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
Temel Çıkarım
film wrinkling is caused by tension fluctuation and thickness unevenness; automatic tension control and homogenization are key
