PURPOSE: A sealing apparatus for plastic film is provided to prevent floating or disconnection regardless of the shape of the heating material by holding with a magnetic plate, and to increase the productivity by sealing with momentary thermal-bonding. CONSTITUTION: A sealing device is composed of a heating supporting plate(30) having a heating wire(50) heating in connecting power, a support member(31) supporting the heating wire, release cloth(32) covering the support member and the heating wire, and a press plate(40) placed on the heating supporting plate. A magnetic plate(34) mounting insulating cloth(33) is inserted between the heating wire and the support member. Floating or disconnection of the heating wire is prevented by supporting the heating wire with the magnetic plate during thermal bonding of plastic film.
