まだヒータ線の熱による膨張。In addition, methods for changing the amount of heat between the overlapping part and other parts of the plastic sheet bag include, for example, placing heater wires concentrated only in the overlapping part, or arranging heaters in the overlapping part in a meandering manner to reduce the watt density. There are ways to raise the height, but the former increases the number of lead wires and makes handling the lead wires complicated, and the latter increases the width of the pad that presses against the plastic sheet bag because the heater wires are meandering. During the meandering of the heater, it becomes a suitable dog / kimono,
The heater wire still expands due to heat.
