9 InkTec Leads New Paradigm in Printed Electronic Materials Antenna Functional film InkTec has focused on the printed antenna which can materialize the highest volume and lowest cost by flexible substrate and electronic materials. Antenna can be applied in the packaging, textiles and smart card industries and printable electronics avoids photolithographic patterning and many of its limitations. InkTec has been developing various functional films such as reflective film, EMI shielding and half conductive film etc. by our own electronic materials and roll to roll facilities. These films are applying display, signage and architectural industry as a decoration or functional parts. According to enlargement of product range, its application will be continuously extended.
