MULTILAYER STRUCTURE

摘要

A multilayer structure including a polyolefin layer (A) and a polyamide resin composition layer (B), wherein the polyamide resin composition constituting the layer (B) contains a polyamide resin (b-1) in which a diamine constituent unit thereof contains a constituent unit derived from a xylylenediamine and a dicarboxylic acid constituent unit thereof contains a constituent unit derived from an ±,É-linear aliphatic dicarboxylic acid having from 4 to 20 carbon atoms and a modified polyolefin (b-2), and the content of the modified polyolefin (b-2) is from 5 to 30 parts by mass relative to 100 parts by mass of the polyamide resin (b-1).
