Heritage & History

C-Line Products was founded in 1948 in Des Plaines, Illinois, just outside Chicago, as a manufacturer of plastic office supply products. The company built its reputation on product quality that outperformed the competition: sheet protectors that didn't yellow with age, report covers with secure-but-not-destructive binding, name badge holders with professional finishes.

C-Line has maintained its Des Plaines manufacturing for over 75 years — an unusual commitment in a category where most competitors moved production to Asia in the 1990s.

All C-Line Products are manufactured in Des Plaines, Illinois, using American-sourced plastic resins and materials. The company extrudes, cuts, and assembles its sheet protectors, report covers, badge holders, and filing products entirely at the Illinois facility.
