Disclosed herein are articles comprising polymer compositions that can provide a barrier to carbon dioxide diffusion. The disclosed polymer compositions can be utilized in packaging to retard or prevent the diffusion of carbon dioxide out of a carbonated liquid, inter alia, a carbonated soft drink. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention. 2.
