One hundred manufacturing jobs are being created in a £40m investment at west Belfast firm Delta Print and Packaging.
The Northern Irish-owned company was formed in 1981 and is based at Kennedy Way.
It designs and manufactures cartons and packaging for the likes of food and electronics companies, including fast food giant McDonald's.
Thirty-one of the new jobs are already in place.
The remaining 69 will see the company's workforce increase to 269.
The company's other customers include Nokia and 95% of its sales are outside Northern Ireland.
Speaking at Tuesday's jobs announcement, First Minister Peter Robinson said indigenous businesses like Delta were "the core of the economy".
"Investment such as this helps Northern Ireland to meet the challenges we have set within our economic strategy - to improve Northern Ireland's economic competitiveness through export-led growth and to increase employment opportunities and prosperity for all," he said.
Mr Robinson said it reinforced the company's 30-year commitment to west Belfast.
Deputy First Minister Martin McGuinness said: "Delta Print and Packaging generate annual wages and salaries of £8m a year to the local economy and this announcement is good news for existing and potential employees and other local businesses."
The announcement was also welcomed by West Belfast MP Paul Maskey, who said it was a good day for the area.
"The senior management and staff of Delta Print have to be commended for their commitment and dedication in attracting investment but more importantly, securing the business and customer base that it currently has," he said.
"Delta Print have already hundreds of people employed in west Belfast and around the world but this further investment from the Executive will increase the workforce by 100 in this constituency. I believe this is a good day for west Belfast."
Terry Cross, Delta's chairman and joint managing director, said: "We are making this major investment in response to opportunities to grow sales across a number of existing customer accounts, in particular with McDonald's, as well as acquiring new accounts.
"Invest NI's support has been vital in enabling us to invest in custom-built, high-technology plant and machinery, extend the factory at Kennedy Way and recruit and train 100 new staff including European sales and marketing personnel, which will give us the infrastructure to take the company to the next level."
