ABSTRACT:
A method for forming a sheet material permeable to gas and not permeable to water includes forming the sheet material by hot pressing two materials together, and discharging static electricity to the sheet material in order to form a number of apertures in the sheet material. The apertures have a size smaller than that of water particles and larger than that of gas particles such that the sheet material is permeable to gas and not permeable to water.
