The bubble for a normally hanging bubble package is thermoformed with an integral base connected with the bottom of the bubble structure by a living hinge at which the base may be pivoted to engage the bottom of the bubble body structure and provide a support for the package in stand-up rather than hanging mode. Structure is provided for fastening the base to the bubble body; such structure may be a latching device comprising male and female elements formed integrally with the bubble at the bottom thereof and in the base, respectively, or may be separately applied adhesive or mechanical fastening devices. The bubble body and flange structure only are bonded to the supporting card leaving the base free to pivot at the hinge to engage the bubble body structure in optional stand-up mode of the package.
