The International Brotherhood of Pulp, Sulphite, and Paper Mill Workers (IBPSPMW) was a labor union representing workers involved in making paper in the United States and Canada.The union was founded on January 6, 1906, as a split from the International Brotherhood of Paper Makers.[3] In 1958, it absorbed the United Wall Paper Craftsmen of North America.[1] However, in 1964, many of its West Coast members left to form the Association of Western Pulp and Paper Workers.[4] On 9 August, 1972, the union merged with the United Papermakers and Paperworkers, to form the United Paperworkers' International Union.
