Method for producing a packaging filled with tablets and one such packaging

Abstract

A process for making a pack filled with a tablet of active substance, by inserting a preformed pack-forming film integrally forming a holding cup a retaining mold, introducing a quantity of uncompressed active substance into the holding cup, compressing the active substance in the holding cup to form a compact tablet in the holding cup itself by means of a compression mold using the holder of the retaining mold as a support.
