(54)PROCESSES AND SYSTEMS FOR IN-LINE INSPECTION OF FUNCTIONAL FILM LAYER CONTAINING DETECTABLE COMPONENT


(57) The continuity of a functional layer of a web is assessed by forwarding the web, detecting the presence of the functional layer and a discontinuity and/or a thin region in the functional layer, and generating a signal in response to the discontinuity and/or thin region. The functional layer comprises a detectable component in a thermoplastic composition. The detecting is carried out by a machine vision system capable of detecting the detectable component in the functional layer. The detectable component can be active or passive. Also included are systems for carrying out the process.
