Abstract
A laminated film in which a metal foil is sandwiched between two polymeric films is cold formed to define one or more blisters, and the base of the blister stamped with indicia, in two discrete stages. The blister is formed in the first stage using a standard technique of advancing a pin in a direction transverse relative to the plane of the film. According to the invention, once the blister forming stage is completed, indicia are stamped into the base of the blister in the second stage by advancing a die from one side thereof to clamp the blister base against a mold held against the other side. The direction of the die and disposition of the die and mold may be selected such that the indicia project inwardly or outwardly from the blister base.
