Rolls with fine groove processing can add functions such as air skew effect, wrinkle removal effect, increased grip, and improved direct transportability. They are particularly effective for optical films, foils, and ultra-thin films! We have received many inquiries from customers. 【Features】 ◎ Avoidance of groove transfer scratches Due to the narrow groove width, the film is less likely to drop into the groove edges, thus avoiding the occurrence of groove transfer scratches. ◎ Air skew effect When the line speed cannot be increased due to film lift caused by air entrapment, fine grooves exhibit the air skew effect. ◎ Increased grip of the roll Rolls with a small wrap angle may slip, but when tension cannot be increased due to product quality, fine grooves enhance grip and prevent scratches.
