Packaging company Bemis has announced plans to close two plants in the US, by the end of 2012.
One plant is located in St Louis Park and another in Minneapolis. Both the twin cities plants manufacture flexible packaging for food under the Curwood brand, a division of the company.
The plants came under Bemis' control along with 21 other facilities when Alcan was acquired by the company in 2010 for $1.2bn, startribune.com reports.
The company's corporate headquarters were shifted to Neenah, Wisconsin, a Fox Valley town in 2006, and its executives were moved closer to its geographic centre.
Bemis will close the St Louis Park plant by 31 August 2012 and the Minneapolis plant between 1 October and the end of 2012.
The closings mean 158 staff will be laid off, with 96 employees at the Minneapolis plant and 62 at the St Louis Park plant losiing their jobs.
US-based Bemis produces plastic packaging and makes packaging for products ranging from diapers to grass seed to snacks, as well as pressure-sensitive packaging and sealed plastic for medical products.
The company has 45 factories in North America, as well as operations in Europe, Latin America, Australia and Asia. Bemis posted revenues of $5.3bn in 2011.
