Abstract: Disclosed are films and laminates which are prepared by known filming or calendering processes using heterophasic propylene polymer compositions comprising: A) 10-60 parts by weight of homopolymer polypropylene having an isotactic index greater than 90, or crystalline copolymer of propylene with ethylene and/or other alpha-olefins containing more than 85% by weight of propylene and having an isotactic index greater than 85; B) 10-40 parts by weight of a copolymer containing prevailingly ethylene, which is insoluble in xylene at room temperature; C) 30-60 parts by weight of an amorphous ethylene-propylene copolymer, soluble in xylene at room temperature and containing 40-70% by weight of ethylene; said propylene polymer compositions having a ratio between the intrinsic viscosities, in tetrahydronaphthalene at 135 DEG C, of the portion soluble in xylene and of the portion insoluble in xylene at room temperature of from 0.8 to 1.2.
