A polyester or copolyester container is made with a heat activated high barrier copolyester label applied to the container sidewall. The process for producing the high barrier container that is a hollow polyester or copolyester body with a barrier label effectively applied to its outer sidewall, includes forming the container by an extrusion blow method, injection blow method, orientation-blow method, or orientation blow-heat set method and applying the barrier label via an "in-mould" technique utilizing a heat-activatable high barrier copolyester resin as the adhesive.
