A container including a shoulder portion terminating at an opening and a sidewall portion extending from the shoulder portion to a base portion. The base portion closes off an end of the container. The shoulder portion, the sidewall portion and the base portion cooperate to define a receptacle chamber within the container into which product can be filled. A barrier layer extends continuously along the base portion, the sidewall portion, and the shoulder portion to the opening and is made of a polymer based material.
