BLOW MOLDING CONTAINER EXCELLENT IN HEAT RESISTANCE

摘要

PROBLEM TO BE SOLVED: To provide a blow molding container of propylene polymer having an excellent combination of flexibility necessary for drain and extrusion of the contents, heat resistance withstanding heat-sterilization or the like, transparency, and shock resistance. SOLUTION: This container 1 is molded with blow molding of a laminated body including a layer containing propylene ramdom block copolymer containing ethylene-propylene ramdom copolymer block of 20-40wt.% which contains copolymer block of 60-80wt.% chiefly composed of propylene, and etylene of 20-40wt.% and having a melt index(MI) of 0.3-15g/10min and another layer containing olefin resin having 113 deg.C or higher melting point.
