  • Publication number: 20200354111
    Abstract: A reclosable package (600) includes a container (602) having an elongate closure region (610) proximate to one edge (608) of the container and bounded on both ends by edge seal regions (620). The closure region includes a reclosable film (630) that seals the container proximate to the edge of the container and has an initial opening strength less than a seal strength of the edge seal regions. Application of an opening force to the reclosable film that is greater than the initial opening strength of the reclosable film may be operable to separate the reclosable film and expose a first reclose surface and a second reclose surface. Contact of the first reclose surface with the second reclose surface and application of a pressure to the reclosable film may be operable to re-adhere the first reclose surface and second reclose surface at a reclose strength.

  • Publication number: 20200216225
    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.
