  • Publication number: 20200354112
    Abstract: The present disclosure is directed to reclosable packages comprising a front wall, a rear wall, and a closure region proximate to an outer edge of the container opposite a bottom of the container. The closure region includes a plurality of seal regions forming a continuous seal between the front wall and the rear wall across a width of the package and at least one of the seal regions is nonlinear. The closure region further includes at least one unsealed region defined between the seal regions. In some reclosable packages, the application of an opening force proximate to the closure region is operable to break the continuous seal between the front wall and the rear wall across a width of the package. The seal geometry may be tuned to adjust the magnitude of opening force required.

  • 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.
