A propylene random copolymer and a film laminate thereof is described having excellent blocking resistance and transparency and substantially maintaining favorable low-temperature heat-sealing properties after corona discharge treatment. The propylene random copolymer of the invention includes a propylene component and an &agr;-olefin component having 4 to 10 carbon atoms, wherein the content of the &agr;-olefin component is in the range of about 6% to about 40% by weight, the intrinsic viscosity [&eegr;] measured in tetralin at 135° C. is not lower than about 0.45 dl/g and not higher than about 5.0 dl/g, and the melting point (Tm) measured by a differential scanning calorimeter and the content of 20° C. xylene soluble fraction (CSX) fulfill a relationship of Tm≦140−35.693 log10(CXS).
