ABSTRACT:
The present disclosure is directed to processes for manufacturing shaped articles for unit-dose packaging with at least one formed recess (e.g., a blister), in particular for unit-dose packaging of pharmaceutical dosage forms. In certain embodiments, the first step of the process is directed to drawing the film material (e.g., metal-plastic foil) with one or more plungers to form a primary contour, the contour having a depth of at least 100% and up to 150% of the depth of the formed recess. The second stage involves shaping the primary contour with one or more plunger(s) to the desired formed recess, with a depth that is less than the depth of the primary contour, while substantially maintaining the surface area of the primary contour formed in the first stage. The formed recess may be formed using warm-forming or cold-forming techniques.
