<p>PROBLEM TO BE SOLVED: To provide a polypropylene container excellent in the balance of transparency and rigidity, therefore, suitable as a container for cosmetics and drinking water, etc., excellent in humidity resistance and low temperature impact resistance, and capable of filling a high temperature content for its excellent heat resistance. SOLUTION: This polypropylene container is manufactured by stretch blow molding of a polypropylene composition containing 0.05-0.5 wt.% nucleating agent (B) and 99.5-99.95 wt.% polypropylene (A), which is obtained by random copolymerization of a propylene and anα-olefin in the presence of a metallocene catalyst, and has an MFR of 0.5-50 g/10 min, anα-olefin content of 0.5-5 wt.%, every ratio of position irregular unit based on 2,1- and 1,3-insertion of a propylene monomer in the total propylene composition unit measured by<13> C-NMR spectrometry of not greater than 0.2%, and an Mw/Mn measured by GPC of 2.5-4.</p> |
