Packaging group Bunzl said trading had been in line with expectations helped by its aggressive acquisition strategy.Third-quarter revenues were up 12%, reflecting underlying growth of 2% and the lift which a string of acquisitions has given the business. At the same time the group announced a further deal. It said it was buying Mexican business Pro Epta, which distributes catering equipment throughout Mexico and is expected to make revenues of £18m in 2013. Bunzl Chief Executive Michael Roney said: "The acquisition of Pro Epta further extends our business in Mexico into the catering equipment sector following the recent expansion into the safety sector with the acquisition of both Vicsa and Espomega."
