Constar International Holdings LLC, a maker of plastic soda bottles, won bankruptcy court approval of three asset sales totaling about $113.6 million, including a sale of the majority of its assets to Plastipak Packaging Inc. for about $102.5 million, Bloomberg News reported yesterday. Bankruptcy Judge Christopher Sontchi yesterday granted the company permission to sell its U.S. and U.K. assets including real estate in Havre De Grace, Md., to the winners of a bankruptcy auction held last week. In 29 rounds of bidding, the sale price for the U.S. assets rose about $34 million, or almost 50 percent, from Amcor Rigid Plastics USA Inc.’s initial bid of $68.5 million.
