%X The components of one ordinary film and three types of degradable films were analysized by differential thermal analysis (DTA) technique, and the processes thermal kinetics of the films were studied. The results showed that the DTA curves of different films had much similarity, which meant that degradable films had similar components as ordinary film, but their added components were different. Pyrolysis reaction orders for each film were about 0.93.The order of pyrolysis activation energies and anaphoric factors of each film was as follows: ordinary film>photodegradable film>photo-calciumdegradable film> biodegradable film.
