PROBLEM TO BE SOLVED: To provide a sealing method of a heat fusible sheet for preventing fracturing a releasable tape occuring due to the differences of a thermal expansion coefficient between a plate heater and the releasable tape, and for preventing clinging of an adhesive material layer on the plate heater. SOLUTION: The sealing method of a heat fusible sheet comprises providing a plate heater fitted in non-contact with a releasable film of a releasable tape composed of a material of excellent releasability, positioning the heat fusible sheet between the plate heater and a press bed arranged opposite to the plate heater, pressing and heating the heat fusible sheet by transferring the plate heater and the press bed in the direction coming close to each other, thereby resulting in sealing the heat fusible sheet and not working great tension on the releasable tape side when the heat surface of the plate heater expands at heating. |
