一种二轴延伸聚醯胺膜，其特徴系在于100℃的沸水中进行5分钟煮沸处理后，所测定之收缩率系制膜时之纵向(MD)及横向(TD)皆为2.0至5.0%，MD之收缩率与TD之收缩率之差为0.5%以下，相对于TD为45°方向与135°方向的收缩率之差为0.5%以下。 Provided is a biaxially oriented polyamide film characterized by, after a boiling treatment in 100℃ boiling water for 5 minutes, the detected shrinkage rate on a longitudinal direction (MD) and a lateral direction (TD) at the time of film-production are both 2.0% to 5.0%, the difference between the shrinkage rate on MD and the shrinkage rate on TD is 0.5% or less, the difference between the shrinkage rate on 45° and 135° |
