A preform configured to be blow-molded into a container. The preform includes a first layer and a second layer. The first layer is an active oxygen scavenger layer including an oxygen scavenger, a catalyst, and a first material having up to 25% recycled polymer. The second layer includes a second material having at least 25% recycled polymer.

A container including a finish, a body, and a base. The finish includes a top sealing surface, threads, and a support flange. The top sealing surface includes only a base layer. The body and the base each include an inner portion made of the base layer, an outer portion made of the base layer, and an oxygen barrier layer between the inner portion and the outer portion.

Multi-layer barrier for a container

A method for manufacturing a container including: forming a preform by injection molding, the preform having a bottom portion, a body portion, and a finish portion including a top sealing surface, threads, and a support flange; forming the preform such that the top sealing surface is made of a base layer, and such that the body portion and the bottom portion are both made of the base layer and an oxygen barrier layer; and forming the container from the preform by blow molding. The top sealing surface includes only the base layer. The body portion and the bottom portion both include an inner portion made of the base layer, an outer portion made of the base layer, and an oxygen barrier layer between the inner portion and the outer portion.

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.

A preform configured to form a container. The preform includes a finish defining an opening and a top sealing surface configured to contact a closure to seal the opening closed. A body portion extends from the finish. A bottom portion 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. An oxygen barrier layer extends along the body portion to the bottom portion and across the bottom portion. A base layer includes an outer portion and an inner portion. The oxygen barrier layer is between the outer portion and the inner portion. The oxygen barrier layer extends along the body portion and the bottom portion.

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.
