PROBLEM TO BE SOLVED: To stably obtain the above film excellent in straightness of tear in the longitudinal direction and having pinhole resistance and dimensional stability in after treatment such as boiling by using a resin having at least one blocked end. SOLUTION: This film is composed of a mixture containing (A) an aliphatic polyamide and (B) a poly-meta-xylylene adipamide at (55-95) to (4-55) weight ratio, and at least one of the terminal group of at least either one resin is blocked. Furthermore, in the film, the end groups of the polyamide are preferably blocked with benzoic acid and the film exhibits preferably two peaks of melting point and, e.g., nylon 6 is preferably used as the component A and a polymamide containing a structural units produced by polycondensation reaction of meta-xylylenediamine with adipic acid is preferably used as the component B. |
