Project Name Development of polyester film, the basic material of audio and video tapes
Year 1970 Director

Polyester film was an original technology developed after years of hard work by a KIST research team led by Nam Seok CHOI. Representing the peak of high-tech material technology, it boasted a very wide range of everyday applications from VTR and audio recording tapes to packaging material, soda bottles, and clothing. Its influence on the diversification of polyester products was tremendous. With polyester film technology transferred from KIST, SK Co., Ltd. initiated mass production of polyester film products in 1978. The money saved from imports and exports amounted to hundreds of billions of won every year. Currently SK is the fourth largest polyester film manufacturer in the world and accounts for about 10% of the global market.
