The Sterling Group Completes the Acquisition of Polychem Corporation

The Sterling Group, an operationally focused middle market private equity firm, today announced the acquisition of Polychem Corporation.  Polychem is a leading manufacturer of polyester (“PET”) and polypropylene strapping in the North American securement packaging industry.  The company manufactures polyester (“PET”) and polypropylene strapping consumables, securement equipment and related products, serving the food and beverage, consumer packaged goods, and industrial industries.

Headquartered in Mentor, Ohio, Polychem has operated as a family business since the 1980s. Polychem is vertically integrated, operating a PET recycling facility which processes bales of post-consumer PET, converting them for use in Polychem’s strapping extrusion lines and for external sale to consumer packaged goods companies. Polychem also manufactures and sells a variety of securement packaging equipment to complement its consumable offering.

“We look forward to working with Polychem to continue to build on the company’s long history of successfully serving customers with quality products and innovative securement solutions,” said Gary Rosenthal, a Partner at The Sterling Group.

The Sterling Group has extensive experience in the packaging sector, including previous investments in Liqui-Box, Exopack and Saxco.
