A high barrier container includes a barrel-shaped container body having a sealed end and an open end, and a closure member. The closure member includes a circular laminated central closure panel and a peripheral flange. The laminated central closure panel includes a top plastic layer and gas-impermeable layer bonded thereto. The closure member is spin welded to the container body such that a spin-weld interface is formed between the open-end part of the container body and the flange.

A high barrier container comprising: a barrel shaped gas-impermeable plastic container body having an open end and a closed end; a container closure member comprising a top plastic layer including a circular central closure panel covering the opening in said container body and a peripheral annular plastic flange formed as an integral component thereof; and a gas-impermeable barrier layer bonded to the bottom of said plastic central closure panel; wherein said closure member is spin-welded to said open end of said container body such that a spin-weld interface is formed directly between said container body and said peripheral flange. A method of forming a high barrier container comprising the steps of: forming a plastic closure member having a central circular closure panel and an integral peripheral annular flange; bonding a gas-impermeable barrier shield to said central closure panel; forming a barrel shaped gas-impermeable plastic container body having an open end and a closed end; and spin-welding said closure member to said container body such that a spin-weld interface is formed directly between said container body and said flange.
