The valve body is composed of two flat plastic films having a bent part on the lower end side and an open part on the upper end side in the fluid flow direction. It consists of a folded piece, and both side edges of the valve body are respectively glued to both side edges of the flow pipe,
The bent portion of the valve body forms a closing portion for preventing the inflow of outside air, and the fluid flows through gaps formed between both inner surfaces of the flow pipe and both outer surfaces of the valve body. is configured to enable, and
A check valve for a vacuum packaging bag, characterized in that the inside and outside of the lower end of the flow pipe are communicated only through the overbody. (2) The check valve for a vacuum packaging bag according to claim (1), wherein the overbody is provided with fine holes that allow only gas to pass through. (3) The check valve for a vacuum packaging bag according to claim (1), wherein the overbody is provided with a hole that allows only gas and liquid to pass through.
