    Abstract: The polypropylene film of the present invention satisfies the relationship: TM≧12.5×HST−900, wherein TM is a tensile modulus (MPa) and HST is a heat seal temperature (° C.), and is well-balanced between the tensile modulus and the heat seal temperature, less tacky, and excellent in processability, transparency and impact resistance. The polypropylene film may be produced from a propylene polymer (A) having: (1) a melting point (Tm) of from 120 to 135° C. as measured by differential scanning calorimeter (DSC); (2) a melting endotherm &Dgr;H (J/g) as measured by the DSC, satisfying the following formula: &Dgr;H≧0.45×Tm+22; (3) a peak top half-width (Th) of 5° C. or lower when measured on an elution curve by temperature rising fractionation; and (4) an intrinsic viscosity [&eegr;] of from 1 to 3 dl/g as measured at 135° C. in tetralin. A multilayered polyolefin resin laminate of the present invention comprises at least one outermost layer made of the above polypropylene film, and is well-balanced between a tensile modulus and a heat seal temperature, less tacky and excellent in slipping and anti-blocking properties.
