On April 1, 1917, Trinity Bag and Paper Company was established at 105 Hudson Street in New York City. For three years the founders of Trinity operated as mill agents and distributors of paper products. By 1920, Trinity's early success enabled them to begin operations as a converter and manufacturer of paper bags and sacks under the name Terminal Paper Bag Co. In that same year Trinity moved its headquarters to 25 West 43rd Street (home of the New Yorker magazine).
