Green Bay Packaging announces leadership transition

Green Bay Packaging (GBP), a Wisconsin-based pulp and paper company, has announced that Executive Vice President Bryan Hollenbach will retire Aug. 31.

Matt Szymanski, who previously was vice president of mill operations, will be promoted to EVP and succeed Hollenbach in this role.

According to GBP, during Hollenbach’s tenure, the company experienced significant growth, investment and modernization. GBP established a new recycled paper mill; constructed two super box plants, each 500,000 square feet; updated nearly every corrugated converting facility; and completed seven acquisitions that expanded GBP’s geographic reach. This includes the recent acquisition of Southern Missouri Container in June 2024.

Hollenbach has been an active supporter of the industry, serving as chairperson of the Fiber Box Association and as chair of the kraft containerboard sector for the American Forest Products Association. He also is a board member of the International Corrugated Packaging Foundation.

Hollenbach's career spans 38 years in the paper industry, with nearly 21 years at GBP and a 16-year tenure at Hoffmaster, where he served as senior vice president of operations.
