The present invention relates to a band sealing device and, more specifically, to a band sealing device which thermally bonds an inlet of a packing material receiving contents after charging the inside of the packing material with gas or evacuating the inside of the packing material. The band sealing device prevents the inflow of air to the inside of the packing material or a discharge of the gas charged inside the packing unit by maintaining the closed state of the inlet when the packing material is transferred to the sealing unit after evacuating or charging gas so that the closed state of the inlet of the packing material can be maintained until the packing material is entered into the sealing unit as bands of the banding unit which are vertically arranged along a guide groove are extended to the front surface of the sealing unit. |
