Brussels gave the deal the green light after concluding the acquisition of the Dutch company would not “significantly impede competition" in the economic bloc.
The transaction will see Ireland-based Ardagh expand into the metal packaging sector on a global basis.
“This is a transformational deal for Ardagh providing us with global reach and scale. The acquisition of Impress will enable Ardagh to become a major force in world packaging,” said Ardagh chairman Paul Coulson.
The deal will see Ardagh to expand outside of Europe to North American and Australasian markets where Impress has established itself as one of the main players in food packaging. Impress is also the second largest supplier of heat processed food cans in Europe and Australasia and the largest supplier of seafood cans worldwide.
