部をシールすることができるものである。As a means for changing the amount of heat between the overlapped portion and the other portion of the plastic sheet bag, for example, a method of arranging the heater wires in a concentrated manner only in the overlapped portion, or arranging the heaters in the overlapping portion in a meandering manner to reduce the watt density Although it is possible to increase the number of lead wires, the number of lead wires increases and the processing of lead wires becomes complicated in the former, and in the latter, the width of the pad pressing the plastic sheet bag is narrow because the heater wire meanders. There is a problem that the heater becomes large during meandering of the heater, and it is difficult to absorb expansion and contraction of the heater wire due to heat. Therefore, as in the embodiment of the present invention, a linear heater wire and a heater for heat sealing, a part of which is located on the back surface of the heat-resistant insulating plate, solves the above problems with a simple configuration. However, the opening of the plastic sheet bag can be sealed.
