Abstract
L'invention concerne les films thermorétractables. Elle se rapporte à un film thermorétractable ayant une couche externe d'un polymère tel que le polyéthylène très ramifié, une couche d'âme formée d'un adhésif thermorétractable qui peut être orientée biaxialement, et une autre couche externe formée d'un mélange de résines polymères comprenant un copolymère de propylène et d'éthylène de type très isotactique, un copolymère de buténe-1 et d'éthylène de type très isotactigue, et de élastomère thermoplastique tel qu'un copolymère d'éthylène et de propylène ou un terpolymère d'éthylène, de propylène et de diène. Le film multicouche formé a d'excellentes propriétés de thermosoudage, de retrait thermique et de résistance mécanique. Application à la fabrication de films convenant à la formation de sacs d'emballage thermorétractables.
