摘要： A reclosable package and processes for making it are disclosed. The reclosable package includes a front panel, a back panel, an upper seal region adapted to be broken to allow a first opening of the reclosable package, a lower seal opposite the upper seal region, a vertical seal extending between the upper seal region and the lower seal on the back panel between the first side edge and the opposing second side edge; and a self-mating fastener disposed adjacent the upper seal region in an interior of the reclosable package. The self-mating fastener includes first and second fastener members each having fastener elements, an open configuration to allow access to the interior volume of the reclosable package, and a closed configuration in which the fastener elements of the first and second fastener members are engaged. In the closed configuration, the self-mating fastener is up to 800 micrometers thick.
