Langkat Disaster Mitigation Agency (BPBD Langkat) head Irwan Syahri said the bodies of the victims, which included three children, were severely burned.
"No survivors have been found so far," Irwan added.
The fire happened in Sambirejo village, which is an hour’s drive from Medan, the capital of North Sumatra.
A local resident named Budi Zulkifli told The Jakarta Post that he heard a blast coming from the factory when he was walking to a nearby mosque for Friday prayers.
The BPBD is focusing on removing the bodies. It will investigate the cause of fire and identify the owners of the factory. Two ambulances are on standby at the site.
