A membrane type pressure relief valve for packaging containers. The valve comprises a plastic overlay that is formed in a way that causes the center portion of the valve to be pre-stressed when applied to a base sheet or a package wall. The forming of the overlay and its subsequent deformation after application to the base sheet or package wall causes the overlay to act as a mechanical assist to close the valve when the valve oil does not fully force the valve closed.
