Hedwin Corp., a generations-old industrial plastics packaging company, is under bankruptcy court protection as a sale to a long-time associate is in the works, PlasticsNews.com reported yesterday. Baltimore-based Hedwin lists debts of slightly more than $18 million and assets of $15 million, according to a chapter 11 filing this month in the U.S. Bankruptcy Court in Baltimore. Hedwin, which dates back to 1946, makes products including pail and drum liners, blow molded containers and a trademarked collapsible liquid container called the Cubitainer. But a June 13, 2013, fire at the company’s Baltimore facility helped push Hedwin to the financial brink. “The fire negatively affected the debtor’s operations, causing a shutdown in certain assembly lines,” the bankruptcy court filing states.
