Abstract: The invention is directed to a one-way valve for a flexible package which comprises a first film layer having at least one first cut line and a second film layer having at least one second cut line, wherein the lines are offset from one another. An adhesive layer is disposed between the first and second film layer, wherein the first film layer, the second film layer, and the adhesive layer define a valve area in which the first film layer and the second film layer are not permanently adhered to each other. The second cut line fluidly connects the interior of the flexible package to the valve area and the first cut line fluidly connects the valve area to the ambient atmosphere surrounding the flexible package. An adhesive pattern is disposed within the valve area and creates a gas flow channel from the second cut line toward the first cut line. An oil occupies the portions of the valve area which are not adhered via the permanent adhesive.
