Wrinkle elimination

Wrinkle elimination

Eliminate the unevenness of the spiral pattern and resolve creases, wrinkle transfer, and curling.

At Showa Marutatsu Co., Ltd., we propose a solution for "wrinkle elimination" using M cores and G cores that have no spiral grooves. In standard paper tubes, the spiral grooves can transfer to films and sheets, causing wrinkles. Since M cores and G cores do not have spiral grooves, such wrinkles do not occur. During the winding of films, various issues can arise due to factors such as the winding core, equipment, and working environment, leading to winding troubles with the film. Kiku wrinkles are one such issue. We propose solutions for Kiku wrinkles from the perspective of the winding core. 【Features】 ■ M cores and G cores do not have spiral grooves, so wrinkles do not occur ■ Eliminates winding wrinkles, wrinkle transfer, and winding habits ■ Proposes solutions for Kiku wrinkles from the perspective of the winding core *For more details, please refer to the PDF materials or feel free to contact us.
