Abstract
By securely affixing or bonding a multi-layer film to the terminating end of a closure/stopper, with the multi-layer film being constructed for promoting the transfer of all of the desirable gases, chemicals, and/or compounds while preventing the transfer of undesirable gases, chemicals, and/or compounds, a unique, closure or stopper having a sealed and/or barrier bearing terminating end is achieved. In this way, wine sealed in the wine bottle by the closure/stopper of the present invention is assured of possessing a long storage life, while also having the flavor, bouquet, taste, and quality desired for the wine fully maintained.
