Uses & General Descriptions

Polarizing Plate Applications
Zero-Defect Base film used for Polarizing Plate Applications such as LCD TV & LCD Monitor; mainly in the process of protection and adhesion coating.
MLCC Applications
Base film with flat thickness, illumination intensity and superb heat-resistance properties for Ceramic sheet molding process of MLCC(Multi Layer Ceramic Capacitor) Applications.
OCA Applications
Base film for Release liners with strictly managed from contamination and superb heat-resistance properties for protecting OCA(Optical Clear Adhesive) Applications.
Optical Applications
Widely used as display base, with excellent light transmittance, mechanical properties, and thermal stability.
Solar Photovoltaic Applications
Clear/White/Milky White-type base film used for protecting the back-side of Photovoltaic application modules.
DFR Applications
Base film with high UV transmittance, illumination intensity and adhesion with the Photo resistance layer, also strictly managed from contamination.
ILC(In-line coated) release liner
In-Line coated base film with release force value-added release liners with strictly managed from contaminants.
Other Industrial films
Films for industrial use provide excellent transparency, adhesion, electrical insulation, cold and hot resistance, and are widely used in PV back sheets, antistatic films, adhesive tape, silicon films, solar control films, gold/silver yarn, cable insulation, and etc.
Shrinking films
Base Films with excellent drawing properties enabled for wrapping any form of products with superb machinability used mainly for bottle wrapping and labels.
Packaging films
Packaging films provide excellent mechanical properties and thermal stability and are widely used in general packaging, printing, laminating, shrinkage labels, and coated products. With high tensile strength, optimum elongation, and workability in a wide range of temperature (-70˚C~260˚C), the products offer excellent dimensional stability. Our packaging films have high transparency, gloss, and chemical resistance, excellent gas barrier and waterproof properties without toxicity or odor, and can be thus used in food packaging.
