Seattle, WA – October 5, 2021 – Rainier Partners (“Rainier”), a private equity firm based in Seattle, WA, today announced the acquisition of JS Ag Packaging (“JS Ag”) by Calpine Containers (“Calpine”), a Rainier portfolio company. Headquartered in Bakersfield, CA, JS Ag provides packaging distribution, labeling, and design services primarily to agricultural customers throughout California.
