PURPOSE: A glue gun for sealing is provided to facilitate to liquefy a wax stick when a document envelope is sealed by transferring thermal energy to the wax stick through a heating wire. CONSTITUTION: A glue gun(20) for sealing includes a main body(24), a holder unit(26), a heating wire(42), and a nozzle unit(28). The main body includes a printed circuit board(32). The printed circuit board electrically connects an outwardly protruded power switch(22) and a resister(30). The holder unit is horizontally arranged in the main body and has a dual pipe of an inner pipe(38) and an outer pipe(40). The inner pipe is formed for the insertion of a wax stick(12). The heating wire is wound between the inner pipe and the outer pipe of the holder unit and is in connection with the resister. The nozzle unit is in connection with one end of the holder unit and induces liquid from the wax stick to the outside.
