Title (EN) METALLIZED PROPYLENE POLYMER FILM WITH GOOD BARRIER RETENTION PROPERTIES
(FR) FILM POLYMERE DE PROPYLENE METALLISE PRESENTANT DE BONNES PROPRIETES DE RETENTION DE BARRIERE
Abstract: front page image
(EN)Multilayer polypropylene films comprising a base layer A, at least one skin layer B adhered to said base layer A and a metal layer M deposited on the surface of said skin layer, wherein said skin layer B comprises a propylene copolymer containing from 3% to 6% by weight of C4-C10 alpha-olefin units, said propylene copolymer having a xylene soluble fraction at 23°C of less than 4,0 wt %, a VICAT softening temperature higher than 135°C and an indentation value according to the VICAT test method lower than or equal to 0.05 mm at 120°C.
(FR)L'invention concerne des films polypropylène multicouches comprenant une couche de base A, au moins une couche active B collée sur la couche de base A, et une couche métallique M déposée sur la surface de la couche active. La couche active B comprend un copolymère de propylène contenant 3 % à 6 % en poids d'unités alphaoléfinique C4-C10. Ce copolymère de propylène présente une fraction soluble dans du xylène à 23 °C inférieure à 4,0 % en poids, une température de ramollissement VICAT supérieure à 135 °C et une valeur d'indentation selon la méthode de test VICAT inférieure ou égale à 0,05 mm à 120 °C.
