L'invention concerne un film plastique pour récipients de liquide à usage médical comprenant un stratifié composé d'au moins trois couches qui renferment respectivement un copolymère séquencé non élastomère d'une oléfine exempte d'un anneau de benzène et de propylène. Ledit stratifié est caractérisé en ce qu'une première couche renferme principalement un homopolymère de propylène, une seconde couche renferme une résine de polypropylène, une résine de polyéthylène et un élastomère thermoplastique, et une troisième couche contient essentiellement un copolymère de propylène et un autre monomère et sert de couche étanche, les trois couches étant superposées sans intervention d'une couche d'adhérence, de telle manière que la seconde couche est une couche intermédiaire.
