双向拉伸聚酯薄膜表面缺陷分析

Research on surface defects of biax-orientation polyester film

通过采用薄膜在线表面缺陷检测设备、正交偏光测试仪和电子显微镜对双向拉伸聚酯薄膜表面缺陷进行研究,分析了各种表面缺陷的形貌特征和形成原因,并提出了相应的解决方法。

Surface defects of biax-orientation polyester film （BOPET） were characterized by online surface defect tester, the orthogonal polarizer and electron microscopy. The morphological characteristics and causes of BOPET surface defects were analyzed and solutions to the defects were proposed,
