摘要: A film is formed by casting a ribbon on a support from a flow cast die while pulling said ribbon toward said support by providing a decompression area. The decompression area is divided into a middle portion, a left portion and a right portion. Degrees of decompression in these three portions satisfy the following formulae: 0

摘要: A cellulose triacetate film having a film thickness from 115 to 135 &mgr;m and a Z value of 0.3 or less wherein the Z value is a slope (g/° C.) obtained by plotting tear strength against temperature in a range between −20° C. and +23° C., and a process for producing the same characterized by drying cast film using drying wind having a temperature T° C. which satisfies T0−15
摘要翻译: 一种三乙酸纤维素薄膜,其膜厚为115至135μm,Z值为0.3或更小,其中Z值为通过将撕裂强度对温度绘制在-20℃之间而获得的斜率(g /℃) 和+ 23℃,以及其制造方法,其特征在于,使用具有温度T℃的干燥风干燥流延膜,该温度满足T0-15
