Nature is the prime source of everythings. So, in this research we selected the plant source for the extraction of resin from acacia catechu. Raw acacia catechu was collected from the plant for the extraction of resin and preparation of film. A mixture of 60% ethanol and 40% benzene was used as solvent for the extraction of resin. After extraction, polymeric films were prepared by casting the extracted solution maintaining the thickness 1 to 3 mm. Now-a-days monomers are widely used for the improvement of properties. In this case monomer (HEMA) was used to improve the mechanical properties of prepared film. Different percentages (10, 12.5 and 15%) of monomer were used with the catechu but 12.5% showed better results than the others two. Different types of high energy radiation (gamma radiation, UV-radiation, etc.) are also widely used for the improvement of different types of properties. With the HEMA grafted catechu film different pass (15, 20 and 25) of UV radiation was applied. The highest result was obtained for the 20 UV radiation pass and the monomer concentration was 12.5% which was taken as optimum. At the optimum condition the highest TS and TM values were 4.5 MPa, and 72MPa respectively as well as the lowest elongation at break was 1.44%.
