Abstract: Disclosed is a multilayered cast film which comprises: A) at least one layer of a crystalline homopolymer of a C3-C6 alpha -olefin, or a random copolymer of propylene with ethylene and/or a C4-C10 alpha -olefin, or a composition of crystalline random copolymers of propylene with ethylene and/or a C4-C8 alpha -olefin (Component A); and B) at least one layer of a propylene homopolymer, or a propylene copolymer with ethylene or a C4-C10 alpha -olefin, or a propylene copolymer with ethylene and a C4-C10 alpha -olefin, having an elongation at break lower than 30% (Component B); said film having an elongation at break greater than 100%.
