Firefighters are being seen working near the 9600 block of W Wingfoot Road at the StarPak manufacturing facility. The Houston Fire Department said a hydraulic press system may have caught fire.
"They do have a containment system that contained the fire until we were able to arrive," said a firefighter on the scene.
The fire has since been extinguished, but emergency traffic remains heavy. Drivers are asked to avoid the area and plan a detour.
According to the company's website, StarPak is a supplier of plastic packaging products.
No injuries were reported.
