Wrinkling during winding of EAA extruded film
Sorun Belirtisi
Transverse wrinkles and longitudinal creases appear after winding of EAA extruded film
Neden Analizi
Film tension uneven, fluctuating ±20%; uneven film thickness causes inconsistent stretching of each section; shrinkage after cooling is anisotropic
Çözüm
1) Automatic tension control system to stabilize winding tension; 2) Improve film thickness uniformity to ±5%; 3) Adjust the guide roller parallelism to <0.05mm/m; 4) Wind after the film is fully cooled to <30°C
Temel Çıkarım
Film wrinkling is caused by tension fluctuations and uneven thickness; automatic tension control and homogenization are the key
