摘要：

Plastics are popularly regarded as an environmental hazard. Ferric stearate photoinitiated high density polyethylene (HDPE) films manufactured as supermarket shopping bags were found to rapidly photodegrade after exposure to ultraviolet (UV) and visible light irradiation. Our studies confirmed manufacturer's claims that the bags would degrade more rapidly than standard UV stabilised bags. The photodegradable bags had the potential to completely degrade and be resorbed into the biosphere without adverse effects.
