Our History

Southland Envelope_5852Southland Envelope Company began in March 1970 as a family business venture. Frank Soloman, Sr. founded the Company on the idea that San Diego County would embrace the market for an envelope manufacturing plant.  Until this point, businesses in the San Diego area had to rely on Los Angeles based companies to meet their envelope requirements.

Frank Sr., along with his wife, Rita, daughters Linda and Dianne, and son Frank, Jr., began working in a small building in La Mesa, Ca. with nothing more than a few pieces of machinery, and the determination to succeed.  Southland Envelope Company was the first envelope manufacturing plant established in San Diego County.
