Connell Industries Inc. of Rahway, N.J., said its hot-fill testing equipment is a way to check blow molded PET bottles for potential problems — before hot filling at a customer's beverage operation.
Graham Packaging Co. LP installed one of the hot-fill bottle testing systems at its plant in Rockwell, Texas, Connell said.
Since it is impossible to test every PET bottle made by Graham Packaging, the Connell system inspects a random lot of 28 units, either every 30 minutes or every hour. Graham added the Connell hot-fill equipment to a testing operation that includes vision and leak-detection systems, according to Connell.
