  The increasing demand for Gas Electron Multiplier (GEM) foils has been driven
by their application in many current and proposed high-energy physics
experiments. Micropack, a Bengaluru-based company, has established and
commercialized GEM foils for the first time in India. Micropack used the
double-mask etching technique to successfully produce 10 cm $\times$ 10 cm GEM
foil. In this paper, we report on the development as well as the geometrical
and electrical properties of these foils, including the size uniformity of the
holes and leakage current measurements. Our characterization studies show that
the foils are of good quality and satisfy all the necessary quality control
criteria.
