    First begun in 1927, Suplee Envelope Company has specialized in manufacturing and supplying mailing, filing, and indexing systems to corporations, law firms and accounting firms nationwide.

    Suplee, though now incorporated, was originally a partnership. Started by the Suplee family in 1927, the company remains a truly family owned business. Today the second and third generations of this founding family continue to provide the exemplary service for which we have become known. This same commitment to our customers has helped us to go from a small Philadelphia company to a major supplier to some of the most prestigious firms in the country. Our sales and distribution networks now include all fifty states, Puerto Rico, Canada, Europe and the Far East.

    Unlike many companies, Suplee Envelope is truly a manufacturer. Our factory is equipped with the most efficient and effective machinery for the fabrication of custom vertical file pockets, wallets and folders. The addition of an on-site print shop makes any of your printed goods look their best. While no one company can make everything that is necessary for a busy office, our partnerships with other manufacturers assure us and you of the finest quality, competitive prices and best service available today.
