Abstract

Feuilles thermoplastiques multicouches du type comportant une couche de polymère styrénique et une couche de polymère oléfinique réunies par une couche intemédiaire de matière polymère comportant au moins une couche de liant. Au moins une couche renfermant des chutes desdites feuilles est disposée au sein de la feuille multicouche, la couche à base de chutes consistant en un mélange desdites chutes avec un copolymères greffé d'un monomère styrénique sur un substrat polyoléfinique. Ainsi au moins une partie des chutes produites lors des opérations de formage de telles feuilles peut être réinsérée de manière satisfaisante dans la feuille multicouche.
