The fire started at 10:35 p.m. at the
Colonial Carton Company
1000 CCC Drive
, which makes boxes for medical and pharmaceutical packaging.
Employees told fire investigators that a piece of material caught fire in a baler.
About 30 employees were inside when the fire broke out. Everyone made it out safely.
The owner, Joe Elphick, of Cary, said he planned to rebuild the part of the building that was destroyed. The building is a total of 72,000 square feet and about one-third of the building was involved in the fire.
The plant employs about 90 people.
