Our History

The Royal Box Company, now known as The Royal Group (or TRG) was founded in 1922 by several Nerenberg siblings, including the oldest sister, Molly, who was the first member of the family to immigrate to the United States from Europe in the early part of the century.

The company began by manufacturing wooden boxes and pallets for the growing manufacturing industry in Chicago.

Throughout the early part of the 1930’s and 1940’s, Royal began investing in equipment and technology to convert corrugated sheets and in the 1950’s purchased its first corrugator. By the 1990’s Royal had acquired several other locations in the mid-western United States and celebrated its 75th anniversary.

In 2007, The Royal Group was acquired by Schwarz Partners. When the Nerenberg family decided to sell the company to the The Schwarz Family of Indianapolis, there was the hope and understanding of The Royal Group legacy continuing to thrive and grow. The Royal Group has continued to grow as intended and remains a key focus in Schwarz Partners corrugated converting operations across the country.
