The photodegradation of a pulp mold container was investigated with ultraviolet light. The results show that the degree of polymerization of samples decreased about 50%, tensile strength decreased 20–30%, sample weight lost 10–16%, and brightness decreased about 20% after 8 weeks of UV irradiation. © 2003 Wiley Periodicals, Inc.
