The invention relates to a monolayer or multilayer long-life packaging containing an anethole-based alcoholic or nonalcoholic beverage, characterized in that the layer in contact with the said beverage is formed from a polymer containing condensed aromatic units. The polymer is especially polyethylene naphthalate (PEN) which has a degree of crystallinity higher than 20%. The invention also relates to a process intended to limit the degradation of anethole-based beverages with the aid of such a polymer. |
