BOPET光学薄膜收卷凹陷的原因分析及解决方法

Cause Analysis and Solution of BOPET Optical Film Winding Depression

介绍了BOPET光学薄膜生产中,在收卷时产生母卷凹陷及纵向条纹的原因,并采取针对性措施,以解决因薄膜收卷凹陷造成的质量问题,为下游客户提供质量稳定的光学级聚酯薄膜基材。

This paper introduces the causes of master roll depression and longitudinal stripe in BOPET optical film production during winding,and takes targeted measures to solve the quality problems caused by film winding depression,so as to provide stable optical grade polyester film substrate for downstream customers.
