Abstract
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.
