By setting like this, avoided fitting mutually because of the interior diaphragm at gas flushing pouch inflation inlet place, the inflation inlet that finds interior diaphragm that can be convenient is inflated, be provided with between the empty heat seal point in addition when annular heat-sealing line is avoided inflating and prevent that empty heat seal point from being widened by actv., influence sealing effectiveness.
Further setting of the present utility model is: be provided with an air inlet shunting in described each sealing column; Described inner membrance heat-sealing line and the setting of side heat-sealing line overlap.
Further arrange and to improve work efficiency.
Below in conjunction with accompanying drawing the utility model is further described:
