Abstract
A tamper-resistant package for an article to which access is intended only by destruction of the package has two webs of sheet material having inner surfaces securable together around their peripheries to form the package with the article lying between the webs. A solvent indicator ink is printed on one of the webs, the solvent indicator ink containing an organic dye which bleeds to a visible part of the package upon application of a readily-available common polar or non-polar solvent. A water-sensitive coating is provided on one of the webs to produce a visible indication if an attempt is made to open the package with water, and a heat-sensitive ink is printed on one of the webs to produce a visible change when an attempt is made to open the package by the use of heat.
