摘要

A method of packaging, comprising the steps of disposing an article in a package and airtightly sealing an air sensitive reagent, which changes color upon contact with air, as at least part of the package for the article such that the seal must be broken to access the article and thereby cause the reagent to contact the air or another agent and change color. A semi-permeable membrane will allow the same reagent to function as a shelf-life indicator.
