Huhtamaki Foodservice Delta had pre-tax profits of £3.5m for 2019, down from £4m.
However, turnover went up 13% from £55m to £62.3m, the accounts show, with staff numbers also up 20% to 428.
The business, based at Kennedy Way Industrial Estate, also makes packaging for other fast-food firms like KFC and Nando s, as well as food companies like Kellogg s.
Delta Print was set up by businessman Terry Cross in 1981. It was sold to Finnish firm Huhtamaki in 2016, and is now led by Huhtamaki Foodservice UK general manager Ciaran Doherty.
In a strategic report with the just-filed accounts, the company said the opening of a second factory with a new production line had brought additional costs early in 2019 but added more revenues later in the year. In the pandemic, the second factory was used for the production of visors in a project with Bloc Blinds, Magherafelt.
