摘要
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.
