Ardagh Group produced aluminium bottle with the Warsteiner Art Collection range of 330ml shaped. The bottles gained the world’s most pre-eminent packaging accolade World star for their use of enhanced printing techniques to represent the work of 6 distinguished contemporary European artists. They are printed in HD dry offset with sharp screens on a metal base by Ardagh. The application of solid covering colours on brushed transparent metal effects and gold tones help to convey the brand’s approach to use modern culture to attract consumers, and particularly a younger and influential target audience, throughout the more than 60 countries where the beer is sold. WorldStars are presented only to those packages which, having already won recognition in a national competition, are compared by an expert panel of judges to similar packages from around the world. Awards are based on the judges' consensus that a package is superior in its own right and better in its class in execution or innovation by comparison.
