Biaxilly oriented polyamide film and its production process |
摘要 |
A biaxially oriented polyamide film which has not only excellent bending pinhole resistance and excellent dimensional stability but also excellent tear linearity in the longitudinal direction of the film. More specifically, the invention provides a biaxially oriented polyamide film having a tear linearity in the longitudinal direction of the film, which includes as a main material nylon 6 and an aliphatic polyamide resin mixed in a weight ratio of from 75:25 to 99:1, wherein the difference in surface tension (dyne/cm) between the nylon 6 and the polyamide other than nylon 6 satisfies the following relationship (1) 3.0</= gamma A- gamma B</=15.0 (1) wherein gamma A is a surface tension of N6 and gamma B is a surface tension of PA.
