Abstract
A process, product, and system for detecting a defective vacuum in a packaged product. The process may include providing a packaged product including a product enclosed within a packaging article. The packaging article may include a film having at least one layer containing a fluorescence-based indicator. The process may further include exposing the packaged product to incident electromagnetic energy to produce an excited fluorescence-based indicator, such that the excited fluorescence-based indicator emits fluorescent electromagnetic energy; and determining, based on the fluorescent electromagnetic energy emitted by the excited fluorescence-based indicator, that gas is present within the packaging article.
