Abstract: The present disclosure is directed to a reclosable package comprises a front wall, a rear wall, and an upper closure. At the upper closure, at least a portion of a surface of the rear wall is sealed to an exterior surface of the front wall at a first adhesion strength. According to embodiments, the application of a force greater than the first adhesion strength to the rear wall in a direction away from the front wall is operable to separate the portion of a surface of the rear wall from the exterior surface of the front wall. After, the return of the portion of the surface of the rear wall and an application of a force on the rear wall in the direction of the front wall is operable to reseal the portion of the interior surface of the rear wall to the exterior surface of the front wall.
