<p><P>PROBLEM TO BE SOLVED: To provide an engagement vessel member for storage having all of flexibility, heat resistance, transparency and cleanness. <P>SOLUTION: The engagement vessel member for storage is made by molding a propylene-based resin composition containing 50 to 100 pts.wt. of a propylene-ethylene block copolymer (α) obtained by successively polymerizing two kinds of specific propylene-ethylene random copolymer components using a metallocene-based catalyst and having a Tm of 110 to 150°C and a single peak of a tanδcurve below 0°C, and 0 to 50 pts.wt. of a thermoplastic resin component (β) having a bending modulus lower than that of the propylene-ethylene block copolymer (α), a density of 0.860 to 0.920 g/cm<SP>3</SP>and a MFR of 1.0 to 50 g/10 min. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
