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°C, of the portion soluble in xylene and of the portion insoluble in xylene at room temperature of from 0.8 to 1.2.
