Companies owned by affiliates of Sun Capital Partners Inc. - Exopack, Britton Group, Paccor, Kobusch-Sengewald GmbH and Paragon Print & Packaging - are combining into one packaging company, which will be called Exopack Holdings Sarl.

Exopack Holdings will be based in Luxembourg, and have 63 plants, 8,650 employees and revenue of more than $2.5 billion.

The five companies all manufacture plastic packaging.

Spartanburg, S.C.-based Exopack produces flexible paper and plastic packaging, often used for snack bags; Britton, headquartered in Cheshire, England, manufactures flexible plastic packaging; Bellevue, Wa.-based Paccor manufactures rigid plastic packaging, used for dairy products and detergents; Kobusch, headquartered in Warburg, Germany, produces customer flexible and rigid plastic packaging for consumer and medical products; and Paragon makes packaging for private label products.

Private equity firm Sun Capital owns all of the companies. The firm says combining the companies will allow them to operate more effectively.

Boca Raton, Fla.-based Sun Capital has been picking up the companies since 2005 when it bought Exopack. The firm invested in Paccor in December 2010, Britton Group in April 2011, Kobusch in December 2011 and Paragon in January.
