BARRIER LAMINATES FOR THE RETENTION OF ESSENTIAL OILS, VITAMINS AND FLAVORS IN CITRUS BEVERAGES AND A METHOD OF MAKING SAID LAMINATE AND LEAK-TIGHT CONTAINERS THEREFROM ABSTRACT A barrier laminate for making containers and cartons that substantially resist the absorption of essential oils and flavoring components, e.g. peel oil, as well as the oxidation of 1-ascorbic acid (vitamin C) normally found in various beverages such as fruit and citrus juices. In a particularly preferred embodiment, the present laminate comprises a substrate material having a thin layer of PET-G (glycol-modified polyethylene terephthalate) bonded to the substrate's inner and outer surfaces, said PET-G layer becoming the beverage-contacting surface of containers made from such a laminate. In other particularly preferred embodiments, the barrier laminate also inciudes one or more intermediate layers of oxygen barrier materials between the laminate's substrate and beverage-contacting layer of PET-G. Also disclosed are methods of making such barrier laminates and containers therefrom.
