The punch assembly includes a housing, and a heat sink provided in and retained by the housing, where the heat sink includes a punch tip that is to provide an opening in the sealed end portion of the package. The punch assembly also includes a coil heater contacting the heat sink to provide heat to the heat sink and the punch tip, where one or more air gaps are provided between the housing and the heat sink to prevent heat transfer from the heat sink to a seal jaw assembly of the form, fill, and seal machine.
