ABSTRACT:
The present invention is a thermoformer which produces zero scrap during the heating, forming and cutting of a blister package. In one embodiment, the thermoformer comprises a pre-cut 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 area 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. The thermoformer further comprises a forming station adapted to form each of the webs. The thermoformer further comprises a cutting station adapted to separate the webs from each other by making a cut along each of the cut areas connecting the webs.
