Investcorp has hired investment banks Barclays Plc and Deutsche Bank AG to run a sale process for Berlin Packaging, the people said this week.
Berlin Packaging, Investcorp, Barclays and Deutsche Bank representatives declined to comment.
Investcorp acquired a majority stake in Berlin Packaging in 2007 for $410 million.
Andrew Berlin created Berlin Packaging in 1988 with the acquisition of Alco Packaging. He agreed to continue as chief executive after the deal with Investcorp. He also owns the South Bend Silver Hawks baseball team and is an investor in the Chicago White Sox baseball team.
Berlin Packaging distributes plastic, glass and metal containers and closures for the food and beverage, household, personal care and healthcare markets.
A sale of the company would be the latest in a wave of deals in the industrial and consumer packaging sectors as a modest economic recovery spurs private equity firms to seek companies with strong cash flows and high barriers to entry.
