A pre-formed plastic shell that holds a small consumer good or pharmaceutical pill, usually sealed to a printed paperboard or foil backing. In manufacturing, these are created on high-speed thermoforming machines that heat a plastic sheet and draw it into a mold cavity. The sealing process requires precise control of heat, pressure, and dwell time.
