ABSTRACT:
The invention herein relates to a method and apparatus for forming (or cold-forming) an embossed blister from a laminated film wherein an indicia is formed on the base of the blister. In particular, the invention involves a single pass process of combining the formation of a blister and the formation of an indicia (embossing) on the blister, wherein the blister-forming pin contains a face with an indicia and is adapted to controllably stretch the laminated film during blister formation to minimize stretching of the film at the base of the blister. The invention is particularly useful in manufacturing processes which involve the formation of blisters having laminated films which contain a metal foil and polymer layer, wherein improved control in the stretching of the laminate during blister formation is desirable.
