Abstract:

A packaged aqueous carbonated beverage comprising a container which replaces at least a portion of COthat permeates through the container or closure. The container comprises a polyester composition including a polyester suitable for packaging aqueous carbonated beverages and a carbonating agent. The aqueous carbonated beverage is disposed in the container such that the aqueous carbonated beverage has direct contact with the container and a closure seals the beverage in the container. The carbonating agent reacts with water in the carbonated beverage forming COfor replacing at least a portion of COthat permeates through the container or closure. A corresponding method of packaging an aqueous carbonated beverage is disclosed.

Abstract:

Overmolded containers and methods of manufacture thereof are disclosed, which may provide enhanced visual and tactile characteristics, enabling innovative packaging designs, improved grippability and thermal insulation. The containers can be made cost effectively manner, with minimal impact on polymer recycling streams. The methods of making the container include the steps of providing a container preform which comprises a thermoplastic polymer, such as a PET copolymer; overmolding an elastomeric material over at least a portion of the preform to form an overmolded preform; and blow-molding the overmolded preform to form an overmolded container. In one embodiment, the overmolded container is a beverage container.
