A torque limiting mechanism used for securing fasteners is described. More specifically, the invention relates to materials and methods suitable for use as packaging materials whereby the appearance of grease, fat or oil staining on the packaging material is reduced or eliminated. A signal electrode is on a ridge on the substrate. The plunger is engaged with the inner surface of the dispensing chamber housing, is capable of sliding in the dispensing chamber housing, and is fluidly sealed to the inner surface of the dispensing chamber housing. For this purpose, an indirect extrusion press can have a maximal distance between a closure piece and an indirect punch that corresponds at least to the sum of the expanses of the tool head and of the block holder in the movement direction. The controller is adapted to progressively cause the vent valve to restrict the flow area of the gas washout vent in response to increases in the pressure of the gas supply.
