Abstract

A liner for a high pressure gas container includes a resin composition containing a polyphenylene sulfide resin and an olefin based resin. The resin composition has a methane gas permeability coefficient of 1.7×10−16 mol·m/m2·s·Pa or smaller at 40° C., and tensile elongation of 50% or greater after fracture at 23° C. A high pressure gas container having such a liner is also provided.
