The affiliates of GS Capital Partners have closed a previously announced equity investment in Plastipak, a global supplier of plastic packaging solutions.

The investment is expected to position the US-based Plastipak to further capitalize on substantial growth opportunities across its global business platform.

Plastipak has been owned and run by the Young family, which will continue to hold a majority stake.

Plastipak designs, manufactures, and distributes plastic containers in four product categories including carbonated and non-carbonated beverages; consumer cleaning; food and processed juices; and industrial, automotive and specialty products.

The company sold about 21 billion preforms and bottles to more than 450 customers from 29 manufacturing facilities, in fiscal 2011.
