Abstract
A container including a finish at a first end of the container defining an opening. A base is at a second end of the container that is opposite to the first end. A shoulder extends from the finish. A body defines an internal volume and extends from the shoulder to the base. A single layer material portion of the container extends from the first end to form at least a portion of the finish. A multi-layer material portion of the container extends from the single layer material portion to the second end of the container and across the base. A transition area is spaced apart from the first end where the single layer material portion transitions to the multi-layer material portion.
