American food service packaging specialist WNA Chattanooga is planning to increase its investment to $33m by installing new production lines.
The latest $11m investment will see the installation of high-speed thermoforming machines at a building near the company's Quintus Loop facilities.
WNA Chattanooga will also renovate the building in order to make space for the new production lines, which will produce plastic clam shells and hinged container packaging.
The company will begin operating new production lines in early 2015, which will increase its workforce by 40 people.
WNA's thermoformed containers will be supplied to customers across south-east and central US.
WNA Chattanooga operations vice-president Greg Dempsey said: "As we've noted with our last expansion, we are the primary US thermoforming operation for WNA.
"There is a strong potential for growth within the small format footprint that we will be initiating, and with this addition, we are able to greatly expand our product offering."
The Chattanooga Area Chamber of Commerce said that WNA has initially leased 40,000ft² of the building, with plans to acquire the remaining part of the building over the next three years in order to have space for 12 production lines.
WNA, a division of The Waddington Group, currently has five plants manufacturing food service and other disposable packaging across the US. The company also operates plants in Montreal, Canada, and Colorado, US.
