Abstract
A nucleonic thickness gauge measures the total electron density of a pigmented thermoplastic film from which a product density and thickness may be derived. The amount of pigment admixed with the thermoplastic film resin in an extruder is controlled in response to a comparison between the thickness measured with the nucleonic gauge and the thickness determined from the actual product weight.
