<p>A method of making a biaxially oriented polypropylene film using a tenter-frame (40) is employed. The method includes low concentrations of a nucleating system mixed with polypropylene which allows better processability and improved tensile properties. The nucleating system comprises a blend of nucleating agents: monocarboxylic acid and dicarboxylic acid. The nucleating system is combined with the polypropylene and hot melt blended then formed into biaxially oriented film.</p> |
