Elastic properties of a polyester film have been investigated by using a nanoindentation test with a flat-ended circular indenter made for the experimental. P-h curves obtained were almost elastic in the first and subsequent cycles in contrast to that of the Berkovich indenter which exhibited a large hysterisis loop caused by the viscosity of the material. Young s modulus estimated in the loop range from 98mN to 392mN. The maximum value at a load of 392mN, 2.63GPa, is comparable to the value obtained by a tensile test, 4GPa.
