ABSTRACT:
A flexible, plastic thin film food package is provided having an elongate opening check valve with an air removal port that allows repeated opening and resealing of the package followed by removal of air and moisture by vacuuming. The top open edge of the food package is bonded to a flexible but rigid frame that fits a lid with the air removal port flat valve. The flat valve is a compressed foam sponge and a thin film housed in a rigid case that is bonded to the lid. Air is removed with a spatula attachment of the vacuum pump that is inserted into the space between the lid and the flat check valve. Once vacuum is induced in the interior of the food package, the film covering the frame is sucked against the lid thereby shutting off influx of air into the package.
