The major industry in Johnsonburg is paper, with the largest mill owned by the Domtar Corporation.

It was built more than a century ago, originally owned principally by the Armstrong family of Philadelphia (1888).

By 1950, it was believed to be the largest coated paper mill in the world.

[10] By the end of 1960s, Curtis Publishing filed for bankruptcy and closed the mill.

Six months later, investors, including industrialist George S. Petty, formed a group called Penntech Papers, to purchase the mill assets, and continued it in operation for the next 20 years.
