Firefighters were called out to another Tamworth factory fire on Friday evening, just a week after an arson attack caused a massive blaze in the town.
The fire, at a factory unit in Ninian Way, was reported at around 8pm, with six fire engines attending and a fire service command unit.
Police closed off the road while the fire was brought under control.
The cause of the fire is not yet known.
It came a week after a huge fire at Boomerang Plastics, on the Lichfield Road Industrial Estate.
Police are treating that blaze as arson, and are appealing for witnesses to come forward.
