A thermoformer, which produces zero scrap during the heating, forming and cutting of a blister package uses a precut roll having a series of adjacent webs connected by a cut area. Each of the webs are defined by an overall length L, a width W, and a radius R. Each of the cut areas are defined by a cut depth D1, said cut depth D1 being in the range of about 25% to 90% of the width W of the webs. The thermoformer further comprises a heating station adapted to heat each of the webs, a forming station adapted to form each of the webs, and a cutting station adapted to separate the webs from each other, by making a cut along each of the cut areas connecting the webs.
