Patent

CA 2143259

The present invention provides a propylene random copolymer and film laminate therof having excellent blocking resistance and transparency and substantially maintaining favorable low-temperature heat-sealing properties after the corona discharge treatment. The invention also provides a film laminate prepared from such a propylene random copoly- mer. The propylene random copolymer of the invention in- cludes a propylene component and an .alpha.-olefin component having 4 to 10 carbon atoms, wherein the content of the .alpha.-olefin component is in a range of 6 to 40 % by weight, the intrinsic viscosity [n] measured in tetralin at 135°C is not lower than 0.45 dl/g and not higher than 5.0 dl/g, and the melting point (Tm) measured by a differential scanning calorimeter and the content of 20°C xylene soluble fraction (CXS) fulfill a relationship of Tm?140-35.693xlog10(CXS).
