Multilayered plastic bottles are disclosed having oxygen scavenging capacity sufficient to maintain substantially zero or near zero (depending on product requirements) presence of oxygen in the bottle cavity for the planned shelf life of the bottled product under specified storage conditions. The bottles feature a layer comprised of oxygen scavenger copolyester and may be used for bottling beer and other products requiring nearly total absence of oxygen for the duration of the target product shelf life.
