Abstract

A preform configured to form a carbonated beverage container. The preform includes a finish defining an opening. A body portion of the preform extends from the finish. A bottom portion of the preform is at an end of the preform opposite to the finish. A longitudinal axis of the preform extends through an axial center of the bottom portion. A base layer is included with the body portion and the bottom portion. The base layer has an inner portion with an inner surface at a carbonated product side of the preform. An outer portion of the base layer has an outer surface at an outer bottle side of the preform. A passive CO2 barrier layer is between the inner portion and the outer portion of the base layer. The passive CO2 barrier layer extends along the body portion to the bottom portion, and across the bottom portion. The passive CO2 barrier layer is arranged closer to the inner surface than the outer surface to increase the shelf-life of carbonated products.
