Abstract
Abstract DEGRADABLE POLYOLEFIN FILM IS DISCLOSED. THE FILM CONTAINS A MATERIAL CAPABLE OF ADVANCING OXIDATIVE DEGRADATION OF THE POLYOLEFIN, AND A WATER-SOLUBLE STABILIZER. THE STABILIZER PREVENTS DEGRADATION OF THE FILM DURING PROCESSING, NORMAL STORAGE, AND USE, BUT IT IS LEACHED OUT OF THE FILM UPON EXPOSURE TO MOISTURE, THEREBY PERMITTING THE FILM TO DEGRADE AFTER USE AND DISPOSAL.
