HOLLOW MOLDED ARTICLE

PROBLEM TO BE SOLVED: To make a hollow molded article excellent in flexibility or the like molded by a method wherein the hollow molded article is formed by injection blow molding of a polyamide resin composition prepared by blending a polyamide resin mixture including a specified amount of 6-66 copolymerized nylon and a modified polyolefin respectively in specified quantities. SOLUTION: On manufacturing a hollow molded article used for a container or the like for food, molding is made by injection blow molding of a polyamide resin composition made up of 50-90 wt.% of polyamide resin mixture including 6-66 copolymerized nylon at least of 70 wt.% or more and 10-50 wt.% of modified polyolefine. The 6-66 copolymerized nylon stands for a copolymerized nylon that is synthesized by using -caprolactam of a material for 6 nylon, an adipic acid of a material for 66 nylon, and salt of hexamethylenediamine as materials. For example, a graft polymerization product of α, β unsaturated carboxylic acid or anhydride thereof to a polyolefine can be given as the modified polyolefine.
