Abstract : Feasibility, performance, and optimization studies, plus realization of the nature of the defects anticipated in package seals under actual production conditions, have shown that the infrared scanner is sensitive, versatile, and reliable. The radiometer can measure temperature changes as small as 0.5C, and with this sensitivity is able to detect seal defects as small as 3.5-mil thread in available packaging materials at rates commensurate with current package production rates. The operating principles of the scanner could be directly applied to a large variety of packaging materials with expected results similar to those found for the tri-laminate material.
