摘要： Valves useful in vacuum compression storage bags are described. The valve includes a check valve, a carrier film having adhesive on a surface thereof, and a plastic stand-off with projecting protrusions. The check valve, carrier film and stand-off each have an opening therethrough which when affixed together align to provide a passageway through the valve. When used with a vacuum compression storage bag, the valve is aligned with a hole through a wall of the bag to provide an air flow passageway through the aligned holes from the interior of the bag through the valve when vacuum force is applied over the valve and the bag sealed. The stand-off extends inside the bag to prevent contents therein from blocking air flow from inside the bag through the valve during vacuum evacuation of air from the bag. The stand-off has a rigidity to prevent collapse of the valve under vacuum force.
