The polypropylene film of the present invention is produced from a propylene polymer having specific characteristics, and is well-balanced between a tensile modulus and a heat seal temperature, less tacky, and excellent in processability, transparency and impact resistance. The other polypropylene film of the present invention is produced from a propylene polymer having specific characteristics, and is less tacky and excellent in resistance to whitening due to peeling, softness and impact resistance. A multilayered polyolefin resin laminate having at least one outermost layer produced from the above propylene polymers exhibits excellent low-temperature heat sealability and sufficient interlaminar strength without the use of an adhesive. The above propylene polymers are produced by polymerizing propylene or polymerizing propylene with ethylene and/or C4-C20 alpha-olefin in the presence of a polymerization catalyst containing a transition metal compound represented by the following formula (I): wherein A1, A2, E1, E2, M, X, Y, q and r are as defined in the specification. |
