        It all depends on the punch involved. For example, many punches required oil-impregnated tape. Others did not. I also recall that it took a punch with a specially-designed block to handle the mylar stuff.

        The widths are standardized for both 5-level (Baudot) and 8-level (ASCII) code. I remember all this from my days servicing Teletype machines (boy, did I just date myself...)
