Chitosan and Algin are known as a natural polymers. Biodegradable films were prepared by solution blend method in the weight ratio of natural polymer(low, medium, high-Chitosan, Algin) for the purpose of useful bioimplants. The possibility of bioimplants, which were prepared from natural polymers as a skin substitute and food wrapping materials were evaluated by measuring biodegradability. This biodegradable films were inserted in the back of rats and their biodegradability was investigated by hematological change evaluation as a function of time to biotransformation. It was found that these values of biodegradable films give some good results with short period test.
