MICHIGAN CITY, Ind. (AP) — A paper box factory that makes cotton-filled jewelry boxes for major retailers plans to expand its production line in Michigan City.

Michigan City Paper Box Co. will invest more than $353,000 in its LaPorte County facility over the next few months, after investing more than $700,000 in two new automated lines four years ago. The (Munster) Times reports that the company will add new technology and maintain 16 jobs at the plant.

The Michigan City Council approved a tax break for the company earlier this month.

Michigan City Paper Box Co. has been family-owned since 1904. It makes packages for Wal-Mart, Gap, K-Mart, Banana Republic, Kohl’s, Coldwater Creek and Lord and Taylor.
