Abstract
An apparatus and associated method which detects breaks and irregularities in a sealing arrangement, especially in heat-sealed, sterile packages by providing a standardized verification bar on the package adjacent a color coded sealing area. The verification bar may indicate examples of a proper seal, an underseal, and an overseal, as well as common seal problems such as bubbles, hairline voids and regular coextensive voids. The package which is especially useful as a sterilization pouch can be visually inspected both by the user of the package contents just prior to use and by the vendor of articles in the packages post assembly of the article into the sealed and sterilized package.
