Who We Are

L&M Corrugated Container Corporation was established in 1979 in Zion, Illinois by Dick Lopes, a well-versed industry executive with prior experience working at a prominent Chicago packaging firm.

Since our founding, our family-owned and operated business has experienced remarkable growth, expanding and upgrading our facilities with state-of-the-art equipment, cultivating a loyal clientele, and winning acclaim and respect along the way. Passed down through generations, Steve Lopes, the founder’s son, led the company for many years. Having played a significant role in the company while working alongside his father, Steven Lopes, Richard’s grandson now serves as the President and CEO of L&M.
