  • 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.
