Abstract

L'invention concerne un film élastique (1) ayant une couche de film élastique (3) à base de copolymères séquencés de styrène, où, dans le cas d'une structure multicouches formée par coextrusion, la couche de film élastique (3) est disposée entre des couches de recouvrement partiellement élastiques (2). La couche de film élastique (3) a une proportion supérieure à 50% en poids de copolymères séquencés de styrène choisis parmi les groupes de substances suivants : copolymères séquencés de styrène-butadiène-styrène (SBS), copolymères séquencés de styrène-éthylène-butylène-styrène (SEBS). Le rapport de l'indice de fluidité (MFI) (à 200°C et à 5 kg) selon la norme ASTM D1238 de la couche de film élastique (3) au MFI des couches de recouvrement partiellement élastiques (2) est supérieur à 0,70.
