Abstract

There is provided a polyethylene terephthalate bottle for liquid-carbonated beverages, the bottle having an interior liquid-contacting surface containing an effective wetting amount of oleic acid to cover any microflaws present and to thereby reduce bubble nucleation and carbonation loss. There is also provided a method of reducing bubble nucleation and carbonation loss in a polyethylene terephthalate bottle by providing, preferably by coating, the interior beverage contacting surface of the bottle with an effective wetting amount of oleic acid.
