Abstract
A reusable adhesive closure including an adhesive strip affixed transversely across a first inner surface of a front wall of a bag at a preselected distance from the opening of the bag; and a first roughened surface strip positioned transversely across a second inner surface of a rear wall of the bag aligned on the wall opposite from the adhesive strip. The first roughened strip is an integral portion of the wall of the bag. The roughened strip is pressable against and into the adhesive strip, whereby a seal is formed by contacting the adhesive strip with the flexible flap member.
