The firm purchased Oskar Plast, which sells disposable packaging products to customers throughout the Czech Republic including retail chains, food processors and other distributors.
Revenue in the year ended 31 December 2013 was CZK284m for the business based in Prague.
The company also bought Bäumer Betriebshygiene Vertriebsgesellschaft and its related company Protemo in Germany.
Bäumer distributes cleaning, hygiene and healthcare supplies to different market sectors while Protemo focuses on healthcare related products to that sector.
Michael Roney, chief executive of Bunzl, said: “The acquisition of Bäumer and Protemo represents our first step into the cleaning and hygiene and healthcare sectors in Germany and should provide a good base for us to develop further in these markets.
“Oskar Plast is an important addition to our existing operations in the Czech Republic and will strengthen our presence there.”
